OBJECTIVE The purpose of this study was to evaluate an MR sequence using half-Fourier acquisition single-shot turbo spin-echo (HASTE) imaging in the assessment of ureteric obstruction. SUBJECTS AND METHODS We prospectively evaluated 111 kidneys in 56 consecutive patients with HASTE MR urography and compared that imaging technique with excretory urography.(More)
OBJECTIVE This study aimed to perform comparisons between diffusion-weighted imaging (DWI) sequences at 3 T with 1.5 T. METHODS Thirteen healthy volunteers underwent abdominal DWI on both 3- and 1.5-T magnets using 3 sequences including breath hold without parallel imaging (PI), breath hold with PI, and free breathing with PI at b50 and b1000. Artifacts(More)
The authors have reviewed the diffusion tensor imaging (DTI) of the brain stem in 19 subjects, consisting of 15 normal volunteers and four multi-system atrophy patients. The study was performed with 1.5 T MRI scanners. DTI was correlated with an automated program allowing superposition of the structural anatomy. Axial, sagittal, and coronal images(More)
Diffusion-weighted imaging has been widely accepted as a powerful imaging technique in neuroradiology. Until recently, the inclusion of diffusion-weighted sequences in body imaging protocols has been hindered by technical limitations. However, with advances in magnetic resonance (MR) imaging technology and technique, these limitations are being overcome.(More)
PURPOSE Our goal was to evaluate biliary obstruction using a T2-weighted, turbo, SE MR sequence with half-Fourier acquisition (HASTE). METHOD A prospective evaluation of 21 consecutive patients with clinical evidence of obstructive jaundice was carried out comparing HASTE MR cholangiography (MRC) to endoscopic retrograde cholangiopancreatography and(More)
