PURPOSE To assess the utility of dynamic MR pancreatography in the evaluation of the behavior of the pancreatic duct after secretin stimulation and to estimate pancreatic exocrine reserve in patients suspected of having acute recurrent or chronic pancreatitis. MATERIALS AND METHODS Ten healthy volunteers and 13 patients suspected of having pancreatic(More)
PURPOSE To study the correlation between apparent diffusion coefficient (ADC) and pathology in patients with undefined breast lesion, to validate how accurately ADC is related to histology, and to define a threshold value of ADC to distinguish malignant from benign lesions. MATERIALS AND METHODS Seventy-eight patients (110 lesions) were referred for(More)
PURPOSE To plot normal fetal lung volume (FLV) obtained with fast spin-echo magnetic resonance (MR) images against gestational age; to investigate the correlation between lung growth and fetal presentation, sex, and ultrasonographic (US) biometric measurements; and to investigate its potential application in fetuses with thoracoabdominal malformations.

BACKGROUND AND PURPOSE This study aimed to investigate brain maturation along gestational age with diffusion tensor imaging in healthy preterm and term neonates. Therefore, a voxel-based study of fractional anisotropy (FA) and mean diffusivity (D(av)) was performed to reveal the brain regions experiencing microstructural changes with age. With tractography,(More)
The articulation of the four French nasal vowels and their oral counterparts has been investigated for four speakers, using magnetic resonance images of the three-dimensional oral and nasal tracts and the cross-sectional velar opening areas. The analysis suggests that the subjects’ anatomy in the oral and nasal tracts influences the articulation, with(More)
PURPOSE To determine the accuracy of 3.0-T pelvic magnetic resonance (MR) imaging in the preoperative assessment of endometriosis and to evaluate colon wall involvement after intrarectal gel administration. MATERIALS AND METHODS Institutional review board approval for this study was obtained, and each patient gave written informed consent. Forty-one(More)
PURPOSE To assess the clinical utility and accuracy of contrast material-enhanced dynamic three-dimensional (3D) T1-weighted magnetic resonance (MR) angiography in the detection of unruptured intracranial aneurysms. MATERIALS AND METHODS A prospective blinded comparison of 3D contrast-enhanced T1-weighted MR angiography with 3D inflow magnetization(More)
PURPOSE To compare duodenal filling seen at magnetic resonance (MR) pancreatography after secretin stimulation and biochemical parameters determined with the intraductal secretin test (IDST) for evaluation of pancreatic exocrine function. MATERIALS AND METHODS MR pancreatography after secretin stimulation and IDST were performed in 41 patients with(More)
Objective. To determine whether MR imaging, including MR urography, is able to assess complicated duplex kidneys and to determine the possible role of MRI compared to other imaging techniques in such uropathies. Material and methods. Twenty consecutive patients (age 1 month– 11 years) presenting with a suspicion of a complicated duplex kidney were(More)
To determine an optimal b value to visualise prostate cancer using diffusion-weighted magnetic resonance imaging at 3 T. Forty one patients with biopsy proven prostate cancer underwent 3 T diffusion-weighted MRI performed with 5 b values (0, 1,000, 1,500, 2,000, 2,500 s/mm2) using a 16-channel coil. Best lesion visibility, the central gland-lesion (CG-L)(More)
