Abstract

Hip prostheses are commonly encountered in the elderly population undergoing prostate magnetic resonance imaging (MRI), causing susceptibility artefacts that can severely degrade image quality especially on diffusion-weighted imaging (DWI). In this issue of European Radiology, Nakai et al specifically investigated the impact of susceptibility artefacts from hip prostheses on the diagnostic performance of MRI of the prostate [1]. The authors report the results from a large population that included three centres, for a total of 11,319 examinations, 5% of which with hip arthroplasty. Susceptibility artefacts from hip replacement graded as ‘moderate’ or ‘severe’ were reported in 57% of the cases, with a decreased cancer detection rate compared to patients without hip prostheses (74%). The reduced cancer detection rate in such patients was mainly attributed to an increased frequency of MRI-negative calls, likely due to the non-visibility of lesions with restricted diffusion. In addition, a lower pathological confirmation rate was observed for Prostate Imaging and Data Reporting System (PI-RADS) ≥ 3 lesions.
