MR venography of multiple sclerosis.
BACKGROUND AND PURPOSE The distribution of multiple sclerosis (MS) lesions in the brain follows a specific pattern, with most lesions in the periventricular regions and in the deep white matter; histopathologic studies have shown a perivenous distribution. The aim of this study was to illustrate these distribution patterns in vivo using high-resolution MR venography. METHODS Seventeen MS pati...
متن کاملSubtraction MR Venography Acquired from Time-Resolved Contrast-Enhanced MR Angiography: Comparison with Phase-Contrast MR Venography and Single-Phase Contrast-Enhanced MR Venography
OBJECTIVE To evaluate the image characteristics of subtraction magnetic resonance venography (SMRV) from time-resolved contrast-enhanced MR angiography (TRMRA) compared with phase-contrast MR venography (PCMRV) and single-phase contrast-enhanced MR venography (CEMRV). MATERIALS AND METHODS Twenty-one patients who underwent brain MR venography (MRV) using standard protocols (PCMRV, CEMRV, and ...
متن کاملPartially recanalized chronic dural sinus thrombosis: findings on MR imaging, time-of-flight MR venography, and contrast-enhanced MR venography.
BACKGROUND AND PURPOSE The imaging appearance of chronic, partially recanalized dural sinus thrombosis has been incompletely described. We sought to more fully characterize the imaging findings of this entity on MR imaging, time-of-flight MR venography (TOF-MRV), and elliptic centric-ordered contrast-enhanced MR venography (CE-MRV). MATERIALS AND METHODS From a data base of patients with cere...
متن کاملMR venography in the pediatric patient.
BACKGROUND AND PURPOSE Little is known about age-related changes in posterior fossa venous anatomy on 2D time-of-flight MR venography (MRV) or about artifacts that limit its accuracy in diagnosing venous occlusive disease. We evaluated pediatric appearances of posterior fossa venous drainage. METHODS One hundred and eight children with normal MR imaging or minimal congenital anomalies underwe...
متن کاملHigh-resolution MR venography at 3.0 Tesla.
PURPOSE The aim of this study was to investigate the visualization of small venous vessels in the normal human brain at a field strength of 3 Tesla. METHODS T2*-weighted, three-dimensional gradient-echo images were acquired by exploiting the magnetic susceptibility difference between oxygenated and deoxygenated hemoglobin in the vasculature and microvasculature. The spatial resolution was 0.5...
