Comparison of MR and contrast venography of the cervical venous system in multiple sclerosis.
BACKGROUND AND PURPOSE MRV has been proposed as a possible screening method to identify chronic cerebrospinal venous insufficiency, which may play a role in MS. We report our initial experience comparing MRV and CV in MS patients to evaluate venous stenosis and collateral venous drainage. MATERIALS AND METHODS Time-of-flight and time-resolved imaging of contrast kinetics MRV and CV were perfo...
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 کاملMR 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 کاملComparison of real-time three-dimensional gadolinium-enhanced elliptic centric-ordered MR venography and two-dimensional time-of-flight MR venography of the intracranial venous system.
BACKGROUND To compare 3-dimensional gadolinium-enhanced elliptic centric-ordered (3D GEC) magnetic resonance venography (MRV) with traditional 2-dimensional time-of-flight (2D TOF) MRV for imaging of the intracranial venous system. METHODS Fifty-three patients underwent 2D and 3D MRV, whereby venous structures were evaluated by 2 neuroradiologists. RESULTS Of the 53 patients, 10 were diagno...
متن کاملComparison of leeching and heparin therapy in management of acute venous congestion of limbs in rat
Acute venous congestion leads to blood stasis in the tissue and impaired blood perfusion. Using medicinal leech is an old method for reducing tissue congestion. There are numerous factors in leech saliva and hirudin that have important roles in the leeching beneficial effect. In this study, an animal study was performed to compare leech therapy with heparin therapy in the treatment of acute ven...
