abstract p u rpose: this study aimed to correlation between the grading stenosis and the start back screening tool (sbst) in patients diagnosed with lumbar central canal stenosis (lccs). methods: in a prospective clinical study, a total of 269 patients with lccs were asked to respond to the questionnaire at their first visits. grading of lccs on mri was determined and also the severities of the...

background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...

background: the goal of this study was to determine the reliability of tcd in evaluation of vertebrobasilar arteries in comparison with brain mra in patients suffering from acute vertebrobasilar stroke. methods: samples were patients with definite clinical diagnosis of vertebrobasilar stroke. for all patients brain mri, mra and tcd were performed during the first 48 hours of admission. basilar ...

Introduction: Glioma is the most common type of brain malignancy among adults. Treatment for this type of tumor involves surgery, radiotherapy, and in higher grades, including chemotherapy. The precise grading of the tumor is critical for treatment planning and prognosis determining. Considering the possibility of problems such as errors in tissue sampling during surgery, as we...

BACKGROUND AND PURPOSE A grading system for experimental subarachnoid hemorrhage (SAH) that does not require animal euthanasia is currently unavailable. We proposed a new grading system based on MRI and evaluated the feasibility of this method in a mouse model of SAH. METHODS SAH was induced by endovascular perforation in adult male C57BL/6 mice. Mice underwent MRI 24 hours after SAH and were...

Background: The nuclear grading of ductal carcinoma in situ (DCIS) affects its clinical risk. aim this study was to investigate the possibility predicting DCIS, by magnetic resonance imaging (MRI)-based radiomics features. And develop a nomogram combining features and MRI semantic explore potential role radiomic assessment DCIS grading.

Objective: To assess the clinical validity of a new grading system based on T2weighted magnetic resonance imaging (MRI) for lumbar disc degeneration Study Design: Retrospective study Overview of the Literature: Various MRI classification criteria have been widely used for evaluation of intervertebral disc pathology. However, there is still considerable controversy regarding the MRI factors that...

This paper describes a fully automatic system for obtaining the standard Pfirrmann degeneration grading of individual intervertebral spinal discs in T2 MRI scans. It involves detecting and labelling all the vertebrae in the scan and then learning a regression from the disc region to the grading. In developing the regression function we investigate a spectrum of support regions which involve dif...
