Some of the most painful medical malpractice cases begin with a troubling fact: the test was done.
The patient had a CT scan, MRI, X-ray, mammogram, or ultrasound. The images existed. The abnormal finding may have been visible. But somewhere in the process, something broke down.
The radiologist may have missed the finding. The report may have described it in a way that did not make the risk clear. The report may have been sent, but no one made sure the treating doctor saw it. Or the treating doctor may have failed to follow up.
By the time the problem is finally found — sometimes months or years later — the patient may be facing a later-stage cancer, a missed stroke, an untreated injury, or another serious condition that might have been treated earlier.
Radiology errors can be hard for patients and families to discover. The mistake is not always obvious at the bedside. It may be buried in a report, hidden in the images, or discovered only when a later doctor looks back and sees that the finding was there before.
Patrick Malone & Associates has long handled complex medical malpractice and misdiagnosis cases in Washington, DC, Maryland, and Virginia. Radiology error cases require the same careful approach: a close review of what the images showed, what the report said, what the treating doctors did, and how the delay affected the patient’s outcome.
When Is a Radiology Error Malpractice?
A radiology error may become malpractice when a radiologist fails to identify, report, or clearly communicate a significant finding that a reasonably careful radiologist should have found — and the delay causes serious harm. These cases usually require outside medical experts to review the original images, not just the written report. A treating doctor may also be responsible if they failed to review the results, follow up on a significant finding, or tell the patient what the imaging showed.
What Radiologists Are Responsible For
Most patients never meet the radiologist who reads their scan. They may not know the radiologist’s name. They may not even realize that a physician they have never spoken to played a major role in their diagnosis.
That can make radiology errors feel invisible. But radiologists are doctors. Their job is not simply to describe an image. They must use medical judgment, identify important findings, explain what those findings may mean, and communicate them in a way that helps the treating doctor take proper action.
This is especially important when an imaging study shows something unexpected.
For example, a patient may have a CT scan of the abdomen for stomach pain. The scan may also show part of the lower lungs. If a suspicious lung nodule is visible, the radiologist may not ignore it simply because the lungs were not the main reason for the test.
The American College of Radiology has published detailed guidance on incidental findings — unexpected findings discovered during imaging done for another reason. That guidance supports an important professional expectation: clinically significant incidental findings should be reported clearly so they can be followed up when needed. If a radiologist sees a suspicious abnormality outside the area they were asked to study, they cannot ignore it simply because it falls outside the narrow focus of the original request. The responsibility follows the significant finding, not just the referral question. External source: American College of Radiology Incidental Findings
Radiology errors often fall into two broad categories.
A perceptual error happens when the abnormality was visible on the image, but the radiologist did not see it.
An interpretive error happens when the radiologist saw something, but misunderstood what it meant.
Both types of errors can matter in a malpractice case. But they are not judged in the abstract. The key question is whether a reasonably careful radiologist, looking at the same study under similar circumstances, should have recognized and reported the finding.
Key Takeaways
- Radiologists are doctors, and their work can have a major effect on diagnosis and treatment.
- Important findings generally must be reported clearly, even when they are incidental to the reason the test was ordered.
- A missed finding may involve either a failure to see the abnormality or a failure to understand its importance.
- The legal question is not whether the radiologist was perfect. The question is whether the care fell below the accepted standard and caused harm.
Common Radiology Errors That Can Lead to Serious Harm
Radiology malpractice cases can involve many different types of imaging and many different conditions. Some patterns appear often.
Missed Lung Nodules
A small lung nodule may be visible on a chest X-ray or CT scan before a patient has symptoms of lung cancer. If the nodule is missed or not properly followed, the patient may not learn about the cancer until it has grown or spread.
Not every missed nodule is malpractice. Some findings are very subtle. Some are difficult to see because of the patient’s anatomy, image quality, or other medical issues. But when a nodule was visible and should have been reported, the delay may be legally significant.
Missed Breast Cancer on Mammography
Mammography cases are among the most common radiology malpractice claims. A delayed breast cancer diagnosis can change the patient’s treatment options, prognosis, and quality of life.
Patrick Malone’s existing page on breast cancer malpractice may be useful for readers who want more information.
In these cases, outside radiology experts review the original mammogram images. They look at whether the abnormality was visible, whether it should have led to more testing, and whether earlier diagnosis likely would have changed the outcome.
Missed Stroke Findings
Stroke imaging can be complicated. Early stroke findings may be hard to see, especially on CT scans. But there are cases where signs of stroke, bleeding, or vascular problems were present and should have been recognized or communicated more clearly.
Patrick Malone’s existing page on stroke and our in-depth article on stroke misdiagnosis may be useful here.
In stroke cases, timing matters. A delay can affect whether certain treatments are available and whether brain injury can be limited. These cases often require both radiology and neurology experts.
Missed Fractures or Internal Injuries
Emergency departments are busy. Imaging may be ordered quickly after a fall, crash, or other injury. But speed does not remove the need for careful review.
A missed fracture, internal bleeding, bowel injury, or organ injury can lead to a patient being sent home when they actually need urgent care. In some cases, the harm comes not only from the missed reading but also from the lack of follow-up when symptoms continue or worsen.
Failure to Compare Prior Imaging
Sometimes the problem is not just one scan. It is the failure to compare today’s scan with earlier scans.
A spot that looks uncertain on one study may become more concerning when compared to prior imaging. If the finding is growing, changing, or appearing in a pattern, comparison may be important.
Whether a radiologist should have reviewed prior imaging depends on the facts. But in many cases, comparison with earlier studies is an important part of a careful interpretation.
Key Takeaways
- Radiology errors can involve cancer, stroke, fractures, internal injuries, vascular problems, and other serious conditions.
- The original images matter more than the written report alone.
- Prior imaging can be important because it may show that a finding was changing over time.
- A malpractice case usually turns on whether earlier recognition would likely have changed the patient’s outcome.
When the Report Exists But No One Acts on It
Some radiology cases do not involve a missed finding at all. The radiologist saw the problem and put it in the report. But the report never reached the right person in time, or no one acted on it.
That kind of communication failure can be just as dangerous as a missed read.
For example, a patient may be discharged from the hospital before the final radiology report is completed. The report later shows a serious abnormality. But if no one checks the final report, no one calls the patient, and no one arranges follow-up, the finding may sit unnoticed in the chart.
The American College of Radiology has guidance on the communication of diagnostic imaging findings. It recognizes that timely and clear communication is an important part of patient care, especially when a finding is urgent, unexpected, or clinically important.

This does not mean every imaging finding requires a phone call. But some findings are too serious to rely only on passive report filing. In the right case, the radiologist may need to take extra steps to make sure the treating doctor knows about the result.
Communication failures may happen when:
- A report is sent to the wrong doctor.
- A serious finding is buried in the body of a long report.
- The impression section does not make the concern clear.
- The patient is discharged before the final report is reviewed.
- The ordering doctor never follows up.
- No system exists to make sure abnormal results are closed out.
These cases often involve shared responsibility. The radiologist may have communication duties. The ordering doctor may have follow-up duties. The hospital may have systems that are supposed to prevent abnormal results from falling through the cracks. Families who want to understand how these failures give rise to legal claims can find broader context on our misdiagnosis resource page.
Key Takeaways
- A radiology report is not useful if the right doctor never sees it or no one acts on it.
- Serious findings may require more than simply placing a report in the electronic chart.
- Treating doctors also have a duty to review and follow up on test results.
- Communication failures can create liability for individuals and for the hospital system.
How These Cases Are Investigated
The most important evidence in a radiology malpractice case is usually the imaging itself.
The written report matters, but it does not answer the central question: what was visible on the images at the time?
To answer that question, an attorney must obtain the actual imaging studies. That includes the CT images, MRI sequences, X-rays, mammograms, ultrasounds, or other original studies. Then, qualified medical experts review those images and compare them to later studies.
In many cases, the expert review asks several questions:
- Was the abnormality visible on the earlier study?
- Should a reasonably careful radiologist have recognized it?
- Was the finding reported clearly?
- Should the report have recommended follow-up?
- Did the treating doctor act on the report?
- Would earlier diagnosis or treatment likely have made a meaningful difference?
Sometimes, later medical records include a phrase like, “in retrospect, the prior study showed…” That kind of note can be important. It may suggest that the finding was visible earlier. But it does not replace independent expert review.
Radiology cases often require more than one expert. A radiologist may explain what the imaging showed. A cancer specialist, neurologist, surgeon, or other medical expert may explain whether the delay changed the outcome.
A Note on Hindsight Bias — and How It Is Managed in Case Review
One challenge in every radiology malpractice case is the problem of hindsight. When an expert reviews earlier imaging and knows that the patient later developed cancer, suffered a stroke, or required emergency surgery, it can be arguably difficult to assess whether the finding should have been caught or whether it only looks obvious in retrospect, knowing what eventually happened.
Courts and attorneys are aware of this problem, and there are different approaches to managing it.
In some cases, an outside expert will conduct what is sometimes called a “blind” review — deliberately avoiding learning the outcome before examining the images, in the hope of replicating more closely the conditions under which the original radiologist read the study. The idea is to ask: what should a careful radiologist have seen and reported, looking at this study fresh?
In practice, true blinding is difficult. When a lawyer hires a radiologist to review a study in the context of a malpractice case, the expert knows, without being told the specifics, that something went wrong. A legal referral for case review is itself a signal that a bad outcome occurred. That context cannot be fully removed.
A more rigorous approach — used more often in defense cases because of the expense — involves a reviewing service that inserts the target study into a broader flow of cases the expert is reading, mixing legal and non-legal studies together. The goal is to simulate a realistic reading environment, where the expert does not know in advance which study is under scrutiny. This method is expensive and logistically complex, which is why it is not standard practice for plaintiffs’ attorneys.
These are not reasons to avoid investigating a possible radiology error. They are simply important context for understanding how expert review works, and why the legal evaluation of a missed imaging finding is more nuanced than it might appear.
Key Takeaways
- The images themselves are central evidence.
- A later doctor’s “in retrospect” comment may be helpful, but it is not enough by itself.
- These cases often require both a radiology expert and a specialist who can address causation.
- Hindsight bias is a recognized challenge in radiology case review, and different methods exist to manage it — though none eliminate it entirely.
- Careful timeline work is essential.
Frequently Asked Questions About Radiology Malpractice
How do I know if a radiology error contributed to a delayed diagnosis?
The first step is getting the complete medical records, including the actual imaging studies. A malpractice attorney can work with qualified radiology experts to review the images and determine whether a significant finding was visible earlier. The review also looks at whether earlier diagnosis likely would have changed the patient’s treatment or outcome.
Can there be a claim if the radiologist reported the finding, but the doctor never followed up?
Yes, depending on the facts. If the radiologist clearly reported the finding and communicated it properly, the responsibility may fall more heavily on the treating doctor. But if the finding was serious and the radiologist did not communicate it in a way that reasonably alerted the treating team, the radiologist may also be part of the case.
What if the missed finding was from years ago?
Radiology errors are often discovered long after they happen. That creates important statute of limitations questions. The rules are different in Washington, DC, Maryland, and Virginia, and the timing may depend on when the patient knew or should have known about the injury. Families should speak with a malpractice attorney as soon as they suspect an error.
Is the treating doctor responsible for following up on imaging results?
Often, yes. The doctor who orders the imaging usually has a responsibility to review the results and take appropriate action. If the report shows a serious finding and the doctor does nothing, that may be a separate failure from any mistake made by the radiologist, and it may support a claim depending on the facts.
In Closing
Radiology malpractice cases are often complex because the mistake is not always obvious when it happens. The image may have been taken. The finding may have been visible. The report may have existed. But if the finding was missed, poorly explained, or never followed up, the patient may lose the chance for earlier treatment.
These cases require careful review of the images, the reports, the communication trail, and the medical timeline. When a missed or delayed diagnosis causes serious harm, patients and families deserve a clear answer about what should have happened and whether the standard of care was met.
