Do we really need a radiologist for prostate contouring in radiotherapy?

The authors report a study which aims at assessing whether the help of a radiologist in prostate contouring on a MRI would improve the variability observed between two groups of radiotherapists who were experts or not in prostatic radiotherapy. Five patients suffering from a prostate cancer had three gold grains implanted in their prostate. A dosimetric scanography and a MRI have been performed, and their data have been merged. Prostate contouring was performed by radiotherapists (experts or not in prostatic radiotherapy) with or without MRI. The obtained results show that a radiologist is required, particularly if a high precision treatment must be performed. Short communication
