Differentiation of Pancreatic lesions using Diffusion-Weighted MRI

Differentiation between benign and malignant breast lesions using quantitative diffusion-weighted sequence on 3 T MRI.

AIM To investigate the capability and diagnostic accuracy of diffusion-weighted imaging (DWI) in differentiating benign from malignant breast lesions using 3 T magnetic resonance imaging (MRI). MATERIALS AND METHODS Women with suspicious or indeterminate breast lesions detected at MRI, mammogram and/or ultrasound were recruited for dynamic contrast-enhanced (DCE)-MRI and DWI prior to their bi...

Differentiation of prostate cancer lesions in the Transition Zone by diffusion-weighted MRI

OBJECTIVE To differentiate prostate cancer lesions in transition zone by diffusion-weighted-MRI (DW-MRI). METHODS Data from a total of 63 patients who underwent preoperative DWI (b of 0-1000 s/mm2) were prospectively collected and processed by a monoexponential (DWI) model and compared with a biexponential (IVIM) model for quantitation of apparent diffusion coefficients (ADCs), perfusion frac...

Utility of diffusion-weighted MRI in characterization of adrenal lesions.

OBJECTIVE The purpose of our study was to evaluate the utility of apparent diffusion coefficient (ADC) values for characterizing adrenal lesions and determine if diffusion-weighted imaging (DWI) can distinguish lipid-rich from lipid-poor adenomas. MATERIALS AND METHODS We retrospectively evaluated 160 adrenal lesions in 156 patients (96 women and 60 men; mean age, 63 years). ADCs and signal i...

Automatic Stroke Lesions Segmentation in Diffusion-Weighted MRI

Diffusion-Weighted Magnetic Resonance Imaging (DWI) is widely used for early cerebral infarct detection caused by ischemic stroke. Manual segmentation is done by a radiologist as a common clinical process, nonetheless, challenges of cerebral infarct segmentation come from low resolution and uncertain boundaries. Many segmentation techniques have been proposed and proved by manual segmentation a...

An analysis of compressive and non compressive vertebral lesions using diffusion weighted MRI
