BACKGROUND AND PURPOSE: MR venography is often used to examine the intracranial venous system, particularly in the evaluation of dural sinus thrombosis. It is considered as accurate as MR venography to detect cerebral venous thrombosis. MRV is an excellent method of visualizing the dural venous sinuses and larger cerebral veins. Hypertension which is thus a different site is the collateral veins. A thorough medical history is taken to make sure the procedure will be safe and that the patient is not allergic to the dye. • Direct cerebral venography can identify venous hypertension. 29. the doctor said she will do the procedure through the groin. You lie on an x-ray table. This procedure was performed with an anesthesiologist who monitored and anesthetized the patient. This test is also used when trying to locate and select a vein for bypass graft surgery.
