How Radiology Errors Lead to Misdiagnosis?
April 16, 2026
Modern medicine is an invisible science. When a doctor suspects an illness, they rely on the eyes of the radiologist to look beneath the skin. Whether it is a routine mammogram, an emergency CT scan after a car accident, or an MRI to investigate chronic pain, the radiologist’s report is the foundation of your treatment plan.
But what happens when those eyes fail? When a radiologist misreads an image, the entire medical process collapses. A patient with a growing tumor is sent home with a clean bill of health, while a patient with a clear scan might be subjected to invasive, unnecessary surgery.
At Lowenthal & Abrams, P.C., we understand that a radiology error is a silent catastrophe. Because our legal team includes an on-staff medical doctor and a registered nurse, we do not just take the hospital’s word for it. We review the original imaging discs (DICOM files) to see exactly what the radiologist missed.
What is a Radiology Error in Medical Malpractice?
A radiology error occurs when a medical professional fails to correctly interpret or communicate the findings of a diagnostic imaging study. In the context of a misdiagnosis, these errors generally fall into three categories:
1. Perceptual Errors
This is the most common type of mistake. The abnormality (such as a lung nodule or a hairline fracture) is clearly visible on the scan, but the radiologist simply fails to see it. Research suggests that perceptual errors account for nearly 80% of all radiology-related lawsuits.
2. Cognitive or Interpretive Errors
In this scenario, the radiologist sees the spot or abnormality, but they misidentify it. They might label a malignant tumor as a benign cyst or a shadow caused by the imaging equipment. This leads to a false sense of security for the patient.
3. Communication Failures
Sometimes the radiologist finds the problem but fails to flag it as a critical value. If the finding is not communicated urgently to the ordering physician, the report may sit in a digital inbox for weeks while the patient’s condition worsens.
Why Do Radiology Mistakes Happen?
The pressure on modern radiologists is immense. In 2026, the volume of imaging studies performed in the United States had reached an all-time high, creating a factory environment in many hospital basements.
The Volume Crisis and Fatigue
Radiologists are often required to read hundreds of images per shift. Studies published in the journal Radiology indicate that as a shift progresses, the miss rate increases significantly due to search fatigue. When a doctor spends only seconds looking at a complex MRI, the risk of overlooking a subtle malignancy skydives.
Lack of Clinical Context
A radiologist often works in a vacuum. If the ordering physician provides vague notes (such as pain instead of localized lower right quadrant pain), the radiologist may not know which specific area requires the most scrutiny.
Technical Limitations
While rare, errors can also stem from the tech performing the scan. If the patient moves or the contrast dye is not administered correctly, the resulting image may be noisy or blurred. A negligent radiologist might try to interpret a poor-quality image rather than ordering a retake.
What are the Statistics on Radiology Misdiagnosis?
The data surrounding imaging errors proves that these are not isolated slips: they are systemic failures.
- The Standard Error Rate: The baseline error rate for radiologists is estimated at 3% to 5% according to the American College of Radiology. While 5% sounds low, given the millions of scans performed, this translates to thousands of daily misdiagnoses.
- The Cancer Miss Rate: In lung cancer screenings, studies have shown that nodules are visible on previous, normal X-rays in up to 90% of cases when reviewed retrospectively after a later diagnosis.
- Malpractice Claims: Diagnostic errors (including radiology) are the leading cause of medical malpractice payouts in the U.S. According to the National Practitioner Data Bank (NPDB), these claims consistently command the highest settlement values due to the severity of the permanent harm.
- The Double Burden: A misread scan leads to a 30% to 50% increase in total healthcare costs for the patient because the eventual treatment is more invasive and expensive.
7 Most Common Conditions Misdiagnosed via Radiology
Radiology errors are most dangerous when they involve time-sensitive conditions. At Lowenthal & Abrams, P.C., we frequently see these seven conditions missed on initial scans:
- Lung Cancer: Overlooking small nodules on chest X-rays that are later revealed to be Stage III or IV cancer.
- Breast Cancer: Failing to identify micro-calcifications or architectural distortion on a screening mammogram.
- Brain Hemorrhages: Missing the early signs of a bleed or a stroke on a non-contrast CT scan in the ER.
- Aortic Aneurysms: These are often incidental findings (found while looking for something else). If a radiologist ignores a widening artery while looking at a rib fracture, the result can be a fatal rupture.
- Spinal Fractures: Subtle hairline fractures in the cervical spine are frequently missed in trauma patients, leading to permanent nerve damage.
- Appendicitis: In pediatric patients, radiologists may misinterpret abdominal ultrasounds, leading to a ruptured appendix and sepsis.
- Pulmonary Embolism: Failing to see a blood clot in the lungs on a CT pulmonary angiogram (CTPA).
The Radiology Audit: How We Uncover the Invisible Error

Proving a radiology error requires more than just showing a second opinion. It requires a forensic deep dive into the digital footprint of the original scan. At Lowenthal & Abrams, P.C., our medical-legal team uses three specific tools to hold negligent radiologists accountable.
1. Analyzing DICOM Metadata
Every digital medical image contains metadata: a digital log of how the radiologist interacted with the file. We can often see exactly how much time a radiologist spent on your specific study. If the metadata shows they spent only 40 seconds reviewing a 300-slice CT scan, it becomes a powerful piece of evidence that they rushed the interpretation and breached the standard of care.
2. The Masked Second Opinion
When we send your scans to our network of independent board-certified radiologists, we often perform a masked review. We ask the specialist to look at the scan without telling them where the cancer was eventually found. When a top-tier specialist identifies the abnormality immediately on the original clear scan, it proves the original error was inexcusable and indefensible.
3. Reviewing the Incidental Findings Log
Often, a radiologist is so focused on the reason for the scan (such as a broken bone) that they ignore a suspicious mass in the corner of the image. The law requires radiologists to report all significant findings, even if they are not what the doctor was looking for. We look for these incidentalomas that were visible but never mentioned in the final report.
