Demonstration of Non-Gaussian Restricted Diffusion in Tumor Cells Using Diffusion Time-Dependent Diffusion-Weighted Magnetic Resonance Imaging Contrast

The diffusion-weighted magnetic resonance imaging (DWI) technique enables quantification of water mobility for probing microstructural properties of biological tissue and has become an effective tool for collecting information about the underlying pathology of cancerous tissue. Measurements using multiple b-values have indicated biexponential signal attenuation, ascribed to "fast" (high ADC) an...

Clinical Significance of Diffusion Weighted Magnetic Resonance Imaging on Treatment Efficacy in MS Patients With Acute Attacks

Background: Despite the existence of various imaging methods, the accurate diagnosis of many neurodegenerative diseases is still controversial. The use of advanced imaging techniques, such as the diffusion weighted imaging can be help the early detection of MS and evaluation of the treatment efficacy in these patients. Materials and method: 24 MS patients with acute attack and thirty healthy s...

Diffusion-weighted magnetic resonance imaging in evaluation of gastric cancer.

OBJECTIVE To investigate the role of diffusion-weighted magnetic resonance imaging (DW-MRI) in the diagnosis of gastric tumors and discuss the diagnostic importance and potential use of apparent diffusion coefficient (ADC) measurements. MATERIALS AND METHODS Beginning in March 2009, DW-MRI was added to the routine abdominal and pelvic MR examination for all patients imaged at our institution....
