Intracranial MR venography in children: normal anatomy and variations.
BACKGROUND AND PURPOSE Little information is available regarding the anatomy of the intracranial veins and sinuses that can be shown on MR venograms of children. The aim of this study was to determine the normal venous anatomy and anatomic variants. METHODS Fifty children who were referred for investigation of developmental delay and who had normal results of MR imaging of the brain were recr...
متن کاملCerebral MR venography: normal anatomy and potential diagnostic pitfalls.
BACKGROUND AND PURPOSE MR venography is often used to examine the intracranial venous system, particularly in the evaluation of dural sinus thrombosis. The purpose of this study was to evaluate the use of MR venography in the depiction of the normal intracranial venous anatomy and its variants, to assess its potential pitfalls in the diagnosis of dural venous sinus thrombosis, and to compare th...
متن کاملMR venography in idiopathic intracranial hypertension: unappreciated and misunderstood.
BACKGROUND Venous sinus disease must be excluded before diagnosing idiopathic intracranial hypertension but is found only rarely in typical cases. Magnetic resonance venography (MRV) is the technique of choice for investigating this, and provides images that are diagnostic and easy to interpret. However, recent work using more invasive techniques has documented pressure gradients and stenoses i...
متن کاملHigh-Field MR Venography using Adiabatic T2 Magnetization Preparation
Introduction Highlighting the lumen of veins while attenuating arterial signal in MRI can be of use for several clinical purposes such as guiding the placement of pacemaker leads [1] or the diagnosis of venous thrombi [2]. At a magnetic field strength of 1.5 T, coronary venography has successfully been implemented with magnetization transfer contrast (MTC) [3] prepulses. Unfortunately this appr...
متن کاملAnatomical Variations of Cerebral MR Venography: Is Gender Matter?
PURPOSE Knowledge of variations in the cerebral dural venous sinus anatomy seen on magnetic resonance (MR) venography is essential to avoid over-diagnosis of cerebral venous sinus thrombosis (CVST). Very limited data is available on gender difference of the cerebral dural venous sinus anatomy variations. MATERIALS AND METHODS A retrospective study was conducted to study the normal anatomy of ...
