Analysis of multiparametric microvascular MRI in tumor patients using a model-based cluster approach

چکیده
Introduction In clinical monitoring of brain tumors, Perfusion Weighted Imaging (PWI) contributes to tumor grading and to assess the response to treatment [1]. Beyond tumor perfusion, tumor hypoxia determines the response of various therapeutic approaches including radiotherapy. All these parameters may be mapped with MRI. However, the integration of several MRI maps is difficult. This wealth of information is however difficult to interpret. Moreover, there are tight physiological links between these parameters. It should thus be possible to define clusters of pixels with similar physiological characteristics. In this study, multiparametric MRI data collected on tumor patient were analyzed with a model-based cluster approach.

Dosimetric 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....

Introduction: Multiparametric MRI of different aspects of cerebral ischemic lesions may improve diagnosis of patients with cerebrovascular injury [1]. Nevertheless, spatial and temporal variations in the extent of various pathophysiological processes, complicates straightforward characterization of brain tissue status. In recent years, unsupervised algorithms have been developed to voxel-wise c...

Background: Glioma is the most common primary brain tumor, and early detection of tumors is important in the treatment planning for the patient. The precise segmentation of the tumor and intratumoral areas on the MRI by a radiologist is the first step in the diagnosis, which, in addition to the consuming time, can also receive different diagnoses from different physicians. The aim of this study...
