Imaging the ischaemic penumbra with T2* weighted MRI.

Identifying the ischaemic penumbra using pH-weighted magnetic resonance imaging

The original concept of the ischaemic penumbra suggested imaging of regional cerebral blood flow and metabolism would be required to identify tissue that may benefit from intervention. Amide proton transfer magnetic resonance imaging, a chemical exchange saturation transfer technique, has been used to derive cerebral intracellular pH in preclinical stroke models and has been proposed as a metab...

T2-Weighted Liver MRI Using the MultiVane Technique at 3T: Comparison with Conventional T2-Weighted MRI

OBJECTIVE To assess the value of applying MultiVane to liver T2-weighted imaging (T2WI) compared with conventional T2WIs with emphasis on detection of focal liver lesions. MATERIALS AND METHODS Seventy-eight patients (43 men and 35 women) with 86 hepatic lesions and 20 pancreatico-biliary diseases underwent MRI including T2WIs acquired using breath-hold (BH), respiratory-triggered (RT), and M...

Cardiac and Hepatic T2*-Weighted Magnetic Resonance Imaging

Abstract Background Iron overload is the main transfusion related side effects in patients with transfusion dependent hemoglobinopathies. Severe iron deposition in tissues leads to organ dysfunction. Many organs can be affected such as heart, liver, and endocrine organs. Cardiac failure and liver fibrosis are the consequent of Iron overload in transfusion dependent hemoglobinopathy. Magne...

Functional Mri of the Uterus with Quantitative T2, Diffusion-weighted, and Magnetization-transfer Contrast Imaging

Introduction: Current pelvic MRI protocols rely predominantly on anatomic sequences for evaluation of the uterus. Functional MR sequences may provide imaging biomarkers with added value for the detection, characterization, and follow-up of treatment response of benign and malignant uterine pathology. Examples of functional MR parameters that have been explored within the uterus in separate stud...
