From: Beyond diagnosis: is there a role for radiomics in prostate cancer management?
Sixty-nine-years old patient treated with external beam radiotherapy after MRI targeted biopsy revealed 3+4 Gleason score prostate cancer. Images from pre-biopsy (a−c) as well as post-treatment (d−f) MRI scans are presented. The index lesion (PI-RADS 5) can be appreciated on the T2-weighted images (a, lesion epicentre marked with a white star) as a homogeneous, moderately hypointense area with obscured margins in the right anterior transition zone. Corresponding marked and focal hypointensity on ADC map (b, red region of interest) and hyperintensity on high b value DWI (c, white arrow) are present. On the corresponding post-treatment sequences (d−f), no abnormalities can be detected, suggesting a good treatment response.
