Optimization of clinical target volume delineation using magnetic resonance spectroscopic imaging (MRSI) in 3D conformal radiotherapy of prostate cancer
Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...
متن کاملDosimetric and Radiobiological Evaluation of Multiparametric MRI-guided Dose Painting in radiotherapy of Prostate Cancer
Introduction: Radiotherapy is one of the treatment options for locally advanced prostate cancer, however with standard radiation doses it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study to increase tumor local control rates a new radiotherapy method, known as dose painting (DP) was investigated....
متن کاملMR-only simulation for radiotherapy planning White paper: Philips MRCAT for prostate dose calculations using only MRI data
Highly targeted treatment planning is at the foundation of successful radiotherapy. With its superb and tunable soft-tissue contrast, MRI has in recent years emerged as an imaging modality to drive delineation accuracy of targets and organs at risk. With the introduction of the fi rst commercially available MR-only simulation package, Philips continues to pave the way for the adoption and imple...
متن کاملDosimetric evaluation of synthetic CT for magnetic resonance-only based radiotherapy planning of lung cancer
BACKGROUND Interest in MR-only treatment planning for radiation therapy is growing rapidly with the emergence of integrated MRI/linear accelerator technology. The purpose of this study was to evaluate the feasibility of using synthetic CT images generated from conventional Dixon-based MRI scans for radiation treatment planning of lung cancer. METHODS Eleven patients who underwent whole-body P...
