Three-dimensional fast spoiled gradient-echo dual echo (3D-FSPGR-DE) with water reconstruction: preliminary experience with a novel pulse sequence for gadolinium-enhanced abdominal MR imaging.
To compare three-dimensional fast spoiled gradient-echo dual-echo (3D-FSPGR-DE) with water reconstruction to conventional 3D-FSPGR for gadolinium-enhanced abdominal imaging. ⋯ Gadolinium-enhanced 3D-FSPGR-DE with water reconstruction provides volumetric abdominal imaging with superior image quality, more homogeneous fat suppression, reduced artifacts, and improved image signal and homogeneity.

Comparative StudyMagnetic resonance imaging and spectroscopy for monitoring liver steatosis.
To compare noninvasive MRI and magnetic resonance spectroscopy (MRS) methods with liver biopsy to quantify liver fat content. ⋯ These findings suggest that standard MRI protocols provide a rapid, safe, and quantitative assessment of hepatic steatosis. This is important because MRS is not available on all clinical MRI systems. This will enable noninvasive monitoring of the effects of interventions such as weight loss or pharmacotherapy in patients with fatty liver diseases.

Steady-state free-precession (SSFP) cine MRI in distinguishing normal and bicuspid aortic valves.
To assess the diagnostic sensitivity and specificity of double-oblique true fast imaging with steady-state precession (SSFP) cine MRI in distinguishing normal and bicuspid aortic valves. ⋯ Double-oblique True FISP cine MR imaging of the aortic valve is 100% sensitive and 95% specific in distinguishing normal and bicuspid aortic valves.

Perfusion-weighted magnetic resonance imaging patterns of hypoxic-ischemic encephalopathy in term neonates.
To determine whether an early magnetic resonance imaging (MRI) study using perfusion-weighted imaging (PWI) may define the pattern of brain injury in term neonatal hypoxic-ischemic (HI) encephalopathy. ⋯ PWI is technically feasible in neonates with HI encephalopathy in a reproducible way, permitting comparisons between children. It provides a practical means to identify early after birth the future definitive ischemic areas that may be shown on conventional MRI only later.
