Usefulness of CT-MRI fusion in radiotherapy planning for localized prostate cancer.
We compared the prostate volumes and rectal doses calculated by CT and CT-MRI fusion, and verified the usefulness of CT-MRI fusion in three-dimensional (3D) radiotherapy planning for localized prostate cancer. Three observers contoured the prostate and rectum of 13 patients with CT and CT-MRI fusion. Prostate delineations were classified into three sub-parts, and the volumes and distances to th...
متن کاملUrethrogram-Directed Stereotactic Body Radiation Therapy for Clinically Localized Prostate Cancer in Patients with Contraindications to Magnetic Resonance Imaging
PURPOSE Magnetic resonance imaging (MRI)-directed stereotactic body radiation therapy (SBRT) has been established as a safe and effective treatment for prostate cancer. For patients with contraindications to MRI, CT-urethrogram is an alternative imaging approach to identify the location of the prostatic apex to guide treatment. This study sought to evaluate the safety of urethrogram-directed SB...
متن کامل[Prognostic impact of tumors localized at the prostatic apex].
OBJECTIVE The apex is a particular region of the prostate in its surgical dissection and pathological analysis. We sought to evaluate the prognostic value of the apical localization of prostate tumors. METHOD From 1988 to 2010, data pre- (age, clinical stage, preoperative PSA, biopsy Gleason score) and postoperative (prostate weight, pathologic stage TNM 2010, Gleason score, margin status) of...
متن کاملMRI and CT Image Fusion Based on Wavelet Transform
The objective of Image fusion is to combine information from multiple images of the same scene in to a single image retaining the important and required features from each of the original image. Nowadays, with the rapid development in high-technology and modern instrumentations, medical imaging has become a vital component of a large number of applications, including diagnosis, research, and tr...
متن کاملCT-MRI image fusion for delineation of volumes in three-dimensional conformal radiation therapy in the treatment of localized prostate cancer.
The objective of this study was to assess the utility of CT-MRI image fusion software and compare both prostate volume and localization with CT and MRI studies. We evaluated the differences in clinical volumes in patients undergoing three-dimensional conformal radiation therapy for localized prostate cancer. After several tests performed to ensure the quality of image fusion software, eight pat...
