Consensus Delineation Guidelines for Pelvic Lymph Node Radiation Therapy of Prostate Cancer: On Behalf of the Francophone Group of Urological Radiation Therapy (GFRU)

Urethra contouring on computed tomography urethrogram versus magnetic resonance imaging for stereotactic body radiotherapy in prostate cancer

“…In fact, when we compare the STAPLE contours generated on CT-urethrogram dataset vs MRI dataset, there is also high variability. However, STAPLE is a well-established and commonly used methodology to generate a ‘reference’ or ‘consensus’ contour in other contouring studies [29] , [30] . A T2-weighted MRI sequence was used in this study, which may not necessarily be optimal for urethra visualisation.…”
