Background and Purpose—Multiparametric MRI generates different zones within the lesion that may reflect heterogeneity of tissue damage in cerebral ischemia. This study presents the application of a novel model of tissue characterization based on an angular separation between tissues obtained with the use of an objective (unsupervised) computer.
Methods —A vector tissue signature model is presented that uses multiparametric MRI for segmentation and characterization of tissue. An objective (unsupervised) computer segmentation algorithm was incorporated into this model with the use of a modified version of the Iterative Self-Organizing Data Analysis Technique (ISODATA).Preliminary results demonstrate that this multiparametric tissue characterization helps to better differentiate among neoplasm, edema, and healthy tissue, and to identify tissue that is likely to progress to neoplasm in the future.Multiparametric MRI Tissue Characterization In Clinical Stroke With Correlation to Clinical Outcome: Part 2.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Rationale and Objectives. Treatment of brain neoplasms can greatly benefit from better delineation of bulk neoplasm boundary and the extent and degree of more subtle neoplastic infiltration. Magnetic resonance imaging (MRI) is the primary imaging modality for evaluation before and after therapy, typically combining.
Multiparametric Volumetric MR Characterization of Intracranial Lesions.. MRI acquisitions that map parameters reflecting tissue metabolism and physiology offer considerable potential for improving the yield of diagnostic imaging studies of intra-cranial brain lesions, including better characterization of the type of lesion and increased.

Multiparametric prostate MRI. The role of MRI for the investigation of prostate cancer has radically changed with the advent of multiparametric MRI (mpMRI). It is hoped that mpMRI can help address two of the problems in prostate cancer management: overtreatment and understaging.
Multiparametric MRI with its best soft tissue resolution plays an important role in the management of patients with prostate cancer. It is the recommended imaging modality for patients with an assumed or definitive diagnosis of prostate cancer.
Multiparametric imaging with different functional MRI parameters (mpMRI) visualizes and quantifies the functional processes of cancer development and progression at multiple levels, and provides.
This work demonstrates the potential to use multiparametric MRI to retrieve important information on the tumour microenvironment after radiotherapy. The non-invasiveness of the method also allows longitudinal tumour tissue characterization. Further investigation is warranted to evaluate the parameters highlighted in this study longitudinally.
Pall Mall Medical is working with Consultant Urologic Radiologist, Dr Sanjay Agarwal, who is able to offer the Multi-Parametric MRI scan using our high specification MRI scan. Dr Agarwal will provide a full interpretation of the results and will work with Pall Mall Medical’s Consultant Urologists to arrange treatment plans, where necessary.
