Comparison of two different diffusion weighted imaging sequences for detection of small hepatic metastases: monopolar and bipolar DWI sequences

Comparison Between Three-Dimensional Diffusion-Weighted PSIF Technique and Routine Imaging Sequences in Evaluation of Peripheral Nerves in Healthy People

Introduction: The present study aims to evaluate the Three-Dimensional Diffusion-Weighted reversed fast imaging with steady state free precession (3D DW-PSIF) sequence with respect to imaging of the peripheral nerves; the tibial, medial, and lateral plantar nerves in the lower extremity, ulnar and median nerve in the upper extremity, sciatic nerve, brachial plexus, and lumbosacral plexus, and a...

Comparison of acquired diffusion weighted imaging and computed diffusion weighted imaging for detection of hepatic metastases.

OBJECTIVE To compare the accuracy of acquired diffusion weighted imaging (DWI) (b=1000 s/mm(2)) with that of computed DWI (b=1000 s/mm(2)) for the detection of hepatic metastases. METHODS Two hundred and sixty patients underwent abdominal magnetic resonance imaging (MRI) at 3.0 T for the evaluation of hepatic metastasis, including T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), heavil...

Echo Planar Diffusion-weighted Mri of the Abdomen and Pelvis: Comparison of Free- Breathing Monopolar and Bipolar Spin-echo Sequences in Image Quality and Geometric Distortions

Introduction: Diffusion-weighted magnetic resonance imaging (DWI) exploits the random, thermally induced displacement of water molecules in biological tissue. Most DWI applications in the abdomen and pelvis employ single-shot spin-echo echo-planar imaging (ssEPI) due to its fast acquisition times and resultant robust performance against motion artifacts. Nevertheless EPI-based DWI suffers from ...

Signal Intensity of High B-value Diffusion-weighted Imaging for the Detection of Prostate Cancer

Background: Diffusion-weighted imaging (DWI) is a main component of multiparametric MRI for prostate cancer detection. Recently, high b value DWI has gained more attention because of its capability for tumor characterization. Objective: To assess based on histopathological findings of transrectal ultrasound (TRUS)-guided prostate biopsy as a reference, an...
