Purpose Deep learning methods (DLMs) have recently been proposed to generate pseudo-CT (pCT) for magnetic resonance imaging (MRI) based dose planning. This study aims to evaluate and compare DLMs (U-Net and generative adversarial network [GAN]) using various loss functions (L2, single-scale perceptual loss [PL], multiscale PL, weighted multiscale PL) and a patch-based method (PBM). Methods and Materials Thirty-nine patients received a volumetric modulated arc therapy for prostate cancer (78 Gy)....

Prostate cancer radiotherapy unavoidably involves the irradiation not only of the target volume, but also of healthy organs-at-risk, neighboring the prostate, likely causing adverse, toxicity-related side-effects. Specifically, in the case of urinary toxicity, these side effects might be associated with a variety of dosimetric, clinical and genetic factors, making its prediction particularly challenging. Given the inconsistency of available data concerning radiation-induced toxicity, it is cruci...

Introduction et but de l’etude Pour la prediction de la toxicite, les organes a risque sont consideres classiquement en totalite. L’objectif etait d’identifier d’eventuelles sous-regions dans le rectum et la vessie particulierement a risque de toxicite en cas d’irradiation prostatique. Materiel et methodes Une serie prospective multicentrique de 272 patients recevant une radiotherapie conformationnelle avec modulation d’intensite guidee par l’image a ete analysee. Les matrices de dose de chaque ...

Purpose To apply a voxel-based analysis to identify urethrovesical symptom-related subregions (SRSs) associated with acute and late urinary toxicity in prostate cancer radiation therapy. Methods and Materials Two hundred seventy-two patients with prostate cancer treated with intensity-modulated radiation therapy/image-guided radiation therapy were analyzed prospectively. Each patient's computed tomography imaging was spatially normalized to a common coordinate system via nonrigid registration. T...

Background and purpose Segmentation of intra-prostatic urethra for dose assessment from planning CT may help explaining urinary toxicity in prostate cancer radiotherapy. This work sought to: i) propose an automatic method for urethra segmentation in CT, ii) compare it with previously proposed surrogate models and iii) quantify the dose received by the urethra in patients treated with IMRT. Materials and methods A weighted multi-atlas-based urethra segmentation method was devised from a training ...

Objectif de l’etude La toxicite urinaire apres radiotherapie prostatique est liee a la dose recue par la vessie et probablement par l’uretre. L’uretre n’est cependant pas visible sur une imagerie tomodensitometrque. Les objectifs etaient de proposer une segmentation uretrale automatique sur la tomodensitometrie de planification et de comparer les doses recues par l’uretre et la prostate. Materiel et methode L’algorithme de segmentation uretrale se basait sur 55 tomodensitometries de patients pri...
