Radiologists do work that patients rarely see but depend on completely. They interpret X-rays, CT scans, and MRIs to find and diagnose disease, and an accurate reading can mean catching cancer early enough to treat. A missed one can be devastating. Research continues to show that diagnostic errors in imaging are more common than most people assume, driven by inherent challenges and cognitive biases built into how humans interpret complex images. Understanding why these errors happen matters, both for improving patient care and for knowing your rights if a missed diagnosis harmed you. A Virginia Beach medical malpractice lawyer can help you understand whether an error rises to the level of negligence.
Our firm has advocated for injured patients for more than three decades, and we handle injury and malpractice cases exclusively. You can read more about our background at Shapiro, Washburn & Sharp. Here are the factors researchers have identified behind missed radiology diagnoses.
An Error Rate That Has Barely Changed in 75 Years
The problem is not new. In 1949, radiologist Leo Henry Garland, a former president of the Radiological Society of North America, found that experienced radiologists missed important findings in roughly 30 percent of chest radiographs that were positive for disease. What is striking is how little that figure has moved. Despite the invention of CT, MRI, digital imaging, and decades of advances, researchers today report a similar rate, which points squarely at human factors rather than technology.
One important clarification: that 30 percent figure comes from retrospective review of films already known to be abnormal. A radiologist’s everyday real-time error rate is considerably lower, generally estimated at 3 to 5 percent. Even so, across the enormous volume of imaging performed, those errors add up to a significant number of missed diagnoses.
Cognitive Biases
Much of the problem traces to how the human brain processes information. Radiologists, like everyone, rely on mental shortcuts that can quietly distort judgment. Several biases are particularly relevant:
- Confirmation bias, focusing on findings that support what the radiologist already expects to see
- Availability bias, leaning on the most readily recalled information rather than the full picture
- Satisfaction of search, stopping the hunt for additional abnormalities after spotting the first one
Any of these can cause a reader to overlook a second tumor, misread a subtle finding, or stop short of the full diagnosis.
Visual Perception Challenges
Radiology is intensely visual, and interpreting these images is genuinely hard. Poor image quality, normal anatomical variation, overlapping structures, and the inherent complexity of certain diseases can all make a real abnormality difficult to distinguish. For example, a subtle lung nodule can hide behind a rib or blend into surrounding tissue.
Time Pressure and Heavy Workloads
Radiologists frequently work under significant time pressure, interpreting large volumes of images to keep up with demand. Some estimates suggest that to manage their workloads, radiologists must read an image every few seconds. That pace produces cognitive overload, and the pressure to move quickly measurably raises the chance of missing something.
Experience, Systems, and Communication
Experience is also important. A less-seasoned radiologist may miss a condition they have rarely encountered, while even an expert can falter on a rare disease or an atypical presentation. Beyond the individual reader, systemic failures also contribute. Poor communication between the radiologist and the referring physician, limited access to prior imaging or patient history, and weak follow-up processes can turn a correctable observation into a harmful missed diagnosis.
When a Missed Diagnosis Becomes Malpractice
Not every diagnostic error is malpractice. In a legal claim, the question is whether the radiologist or other provider failed to meet the accepted standard of care, meaning they did something, or missed something, that a reasonably competent provider in the same situation would not have. Proving that typically requires expert testimony from another qualified physician.
Two features of Virginia law are worth knowing. First, the deadline is short and strict. Under Virginia Code § 8.01-243, a medical malpractice claim generally must be filed within two years of the date of injury, which is usually the date the malpractice occurred rather than the date the patient discovered it. In missed-diagnosis cases, where harm may not surface for years, that rule can be especially unforgiving, so acting quickly is important.
Second, Virginia caps what an injured patient can recover. Under Virginia Code § 8.01-581.15, the state limits total damages in a malpractice case, and unusually, that cap applies to all damages combined, economic and non-economic alike. For malpractice claims arising between July 1, 2026 and June 30, 2027, the cap is $2.75 million, rising by $50,000 each year toward a $3 million plateau in 2031.
How We Can Help
A missed diagnosis case turns on proving both that the error fell below the standard of care and that the delay in diagnosis caused real harm. Our approach pairs a thorough review of the imaging and medical records with testimony from qualified medical experts who can explain to a jury what should have been caught and what the consequences were. We have advocated for injured patients for more than three decades, and that experience shows in our results, including a $1.6 million jury verdict for a client who suffered a traumatic brain injury and seizures after a hospital physician failed to properly address her symptoms. Results depend on the facts of each case, but an outcome like that reflects the work these claims require.
