Abstract

The aim of the study was to compare clinical target volumes defined by CT and MRI for 3 dimensional conformal external beam radiotherapy of prostate cancer. CT and T2-weighed MRI images with 3 mm slice thickness were acquired for 13 patients with clinically organ-confined prostate cancer. Target volumes were contoured by two clinicians ("AP" and "SZ") experienced in prostate radiotherapy. Two clinical target volumes were defined: prostate (CTVpros) and prostate with a margin including the proximal 1 cm of the seminal vesicles (CTVpvs). Eight clinical target volumes were outlined for all patients: CTVprosAPCT, CTVprosAPMR, CTVpvsAPCT, CTVpvsAPMR, CTVprosSZCT, CTVprosSZMR, CTVpvsSZCT, CTVpvsSZMR. Volumes were measured in cm3. The volumes of different PTVs were compared using the Student's t-test. Mean CTVpros The aim of the study was to compare clinical target volumes defined by CT and MRI for 3 dimensional conformal external beam radiotherapy of prostate cancer.
