Problematic Body MRI Discrepancy Rates And Errors

Problematic Body MRI Discrepancy Rates and Errors

2020-10-26 14:55:50

Previous studies have outlined disagreement between radiologists and inconsistent secondary interpretations of MRI scans. Researchers at the University of Vermont and the University of Southern California Medical Center have recently published the first study to focus on secondary interpretations of body MRI evaluated by type of likely error. According to the journal article, up to 70 percent of body MRI interpretations have at least one discrepancy. Since most of these errors are cognitive, a push for sub-specialty trained providers to read these studies is crucial. Interpretation errors, especially those in radiology, are particularly common with MRI scans. Pelvic and abdominal imaging are the most easily misread. These mistakes commonly lead to delayed or improper treatment plans. Discrepancy rates can range from two percent to six percent. Secondary interpretations can be as high as 56 percent, according to existing research.

Researchers retrospectively reviewed 357 secondary body MRI reports captured between January 2015 and December 2018 to determine the actual discrepancy rate. Initial reports were analyzed, and those with discrepancies were divided.

At least one discrepancy was identified in 246 cases, or 68.9 percent. A secondary discrepancy was found in 54 of those cases. Most differences were attributed to cognitive errors (68.8 percent), and secondary discrepancies, considered perceptual errors, accounted for 59.3 percent. To thoroughly examine the reasons behind these discrepancies, researchers found that faulty reasoning (misclassification of the abnormality) was responsible for 34.3 percent of all instances, including 37.8 percent of primary discrepancies. Additionally, search satisfaction occurred with 37 percent of second discrepancies and 15 percent of overall discrepancies.

The team hypothesized that MRI scans were ordered to answer a specific question. Once that question was answered, the radiologist likely did not examine the rest of the scan for other abnormalities. The discrepancy rates are higher than what was previously reported due to several factors. General radiologists might be unaware of the MRI's high sensitivity and ability to determine specific diagnoses. Body imaging frequently has the highest error rates, and double-reading by sub-specialists also increases the discrepancy rate.
