Cerebral angiography and venography for evaluation of cerebral venous thrombosis.
Cerebral venous thrombosis is an uncommon, but important cause of stroke due to its high morbidity. Though conventional catheter based angiography is becoming replaced by newer, noninvasive imaging modalities, it still plays an important role in the evaluation of patients with suspected sinus or venous thrombosis. Techniques of angiography, normal anatomy and variants, and pathological drainage...
متن کاملCerebral venous thrombosis: diagnostic accuracy of combined, dynamic and static, contrast-enhanced 4D MR venography.
BACKGROUND AND PURPOSE MR including MRV is an established method to diagnose CVT. However, it remains unsettled which MR imaging modalities offer the highest diagnostic accuracy. We evaluated the accuracy of a combined, dynamic (1.5 seconds per dataset) and static (voxel size, 1.1 x 0.9 x 1.5 mm), contrast-enhanced MRV method (combo-4D MRV) relative to other established MR/MRV modalities. MAT...
متن کاملRadionuclide plethysmography and Tc-99m red blood cell venography in venous thrombosis: comparison with contrast venography.
Radionuclide plethysmography (RPG) is a new technique that uses Tc-99m labelled red blood cells to ascertain changes in venous volumes by detecting the change in counts in response to the inflation and deflation of proximal thigh cuffs. Diagnosis of ileofemoral venous occlusion is possible using this technique, which also provides kinetic data of venous outflow. A range of normal values was def...
متن کاملProspective comparison of emergency physician-performed venous ultrasound and CT venography for deep venous thrombosis.
BACKGROUND Venous thromboembolic disease is a major cause of mortality and morbidity. OBJECTIVES The aim of this study is to compare emergency physician-performed ultrasound (EPPU) of the lower extremities with CT venography (CTV) in emergency department (ED) patients undergoing workup for pulmonary embolism (PE). METHODS This was a prospective study performed at a busy academic ED. Adult p...
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...
