Diffusion-weighted MR in chronic periaortitis, a new technique has entered the clinical arena

Diffusion-Weighted MR Imaging of Pancreatic Cancer and Chronic Pancreatitis

Diffusion-weighted MR imaging of the brain.

Diffusion-weighted magnetic resonance (MR) imaging provides image contrast that is different from that provided by conventional MR techniques. It is particularly sensitive for detection of acute ischemic stroke and differentiation of acute stroke from other processes that manifest with sudden neurologic deficits. Diffusion-weighted MR imaging also provides adjunctive information for other cereb...

Diffusion-Weighted MR Imaging in Brain Tumor

Primary neoplasms of the central nervous system (CNS) have a prevalence of between 15,000 and 17,000 new cases annually in the United States and are estimated to cause the deaths of 13,000 patients. Gliomas are the leading cause of primary CNS tumors, accounting for 40–50% of cases and 2–3% of all cancers4. Despite new treatment techniques, patients’ survival still remains very low, varying bet...

Diffusion-weighted MR imaging in gynecologic cancers

Diffusion-weighted imaging (DWI) reflects changes in proton mobility caused by pathological alterations of tissue cellularity, cellular membrane integrity, extracellular space perfusion, and fluid viscosity. Functional imaging is becoming increasingly important in the evaluation of cancer patients because of the limitations of morphologic imaging. DWI is being applied to the detection and chara...

Cardiac diffusion-weighted MR imaging in recent, subacute and chronic myocardial infarction: a pilot study

PURPOSE To investigate the clinical feasibility of diffusion-weighted imaging (DWI) to detect recent myocardial infarction (MI) and to differentiate it from subacute and chronic MI, with late-gadolinium enhancement (LGE) sequence as reference. Furthermore, to measure variation of the myocardial apparent diffusion coefficient (ADC) according to the age of MI. MATERIALS AND METHODS Seventy-four...
