A comparison of dosimetric parameters between tomotherapy and three-dimensional conformal radiotherapy in rectal cancer
PURPOSE Tomotherapy for intensity-modulated radiation has been demonstrated to reduce unnecessary irradiations to adjacent organs at risk (OARs). The purpose of this study was to compare the dosimetric parameters between Tomotherapy and three-dimensional conformal radiotherapy (3D-CRT) in rectal cancer patients. MATERIALS AND METHODS We redesigned three-dimensional conformal plans for 20 rect...
متن کاملDosimetric comparison between intensity modulated radiotherapy and three dimensional conformal radiotherapy planning in patients with locally advanced cervical carcinoma
Background: External beam radiotherapy (EBRT) is mainstay of treatment in patients with locally advanced cervical carcinoma (LACC). Three dimensional conformal radiotherapy (3DCRT) and intensity modulated radiotherapy (IMRT) are mainly used in EBRT. However which one is superior is still controversial. Materials and Methods: Forty patients of LACC treated with IMRT were selected for this study....
متن کاملComparison of Volumetric Modulated Arc Therapy and Three-Dimensional Conformal Radiotherapy in Postoperative High-Grade Glioma: A Dosimetric Comparison
Introduction: We aimed to dosimetrically compare three-dimensional conformal radiotherapy (3D-CRT) and volumetric modulated arc therapy (VMAT) in terms of planning target volume (PTV) coverage, organ at risk (OAR) sparing, and conformity index (CI). Material and Methods: Planning data of 26 high grade glioma (HGG) patients were used. Prescrib...
متن کاملDosimetric evaluation of Tomotherapy and four-box field conformal radiotherapy in locally advanced rectal cancer
PURPOSE To report the results of dosimetric comparison between intensity-modulated radiotherapy (IMRT) using Tomotherapy and four-box field conformal radiotherapy (CRT) for pelvic irradiation of locally advanced rectal cancer. MATERIALS AND METHODS Twelve patients with locally advanced rectal cancer who received a short course preoperative chemoradiotherapy (25 Gy in 5 fractions) on the pelvi...
متن کاملDosimetric Comparison between Intensity Modulated Radiotherapy and 3 Dimensional Conformal Radiotherapy in the Treatment of Rectal Cancer
Objective: To compare dosimetric parameters of 3 dimensional conformal radiotherapy (3 DCRT) and intensity modulated radiotherapy (IMRT) in terms of target coverage and doses to organs at risk (OAR) in the management of rectal carcinoma. Methods: In this prospective study, conducted between August 2014 and March 2016, all patients underwent CT simulation along with a bladder protocol and target...
