Abstract:
PURPOSE:To evaluate the adherence rate to Prostate Imaging-Reporting and Data System version 2 (PI-RADS v2) minimum technical standards of prostate magnetic resonance imaging (MRI) in Korean medical institutions.
MATERIALS AND METHODS:This study included 103 prostate MRI examinations from 85 outside medical institutions performed from March 2015 to January 2018. The difference in adherence rate to minimal technical standards of PI-RADS v2 was compared using a Fisher's exact test between subgroups divided by the magnetic strength of MRI machine, type of medical institution and presence of genitourinary radiologist.
RESULTS:Diffusion-weighted imaging (DWI) was obtained frequently in examinations performed in a 3-T machine, in university hospitals and in medical institutions where genitourinary radiologist work in than the others (p < 0.001, p < 0.001, p = 0.003). Many minimum technical standards of PI-RADS v2 showed significantly lower adherence rate in a 1.5-T machine, in a non-university hospital and in a medical institution without genitourinary radiologist than the others.
CONCLUSION:The frequency of obtaining DWI and the adherent rate to some of the PI-RADS v2 minimum technical standards were significantly higher in 3-T machines, university hospitals and medical institutions with a genitourinary radiologist.
