Flow chart of study inclusion criteria. Flow chart showing study inclusion and exclusion criteria. From May 2003 to July 2012, a total of 243 adult patients met the inclusion criteria from both institutions combined. Twenty-three patients were excluded because of undisclosed previous surgery or treatments before the MRI exam (upon re-exam), missing or inconclusive surgery and/or histopathology after the MRI exams, as well as corrupted MRI data. The final study sample for analysis was 220 patients.
