This study was undertaken to determine the impact of dural sinus venography and pressure measurements in the evaluation of patients with meningiomas involving the dural sinuses. Of three patients who had MR imaging, arteriography, and dural sinus venography, the latter method better delineated the site and extent of tumor invasion in all three patients. Pressure measurement in one patient refle...

Duplex ultrasound is used in many radiology departments as the first line of investigation for symptomatic deep venous thrombosis. Before changing the practice of our department from venography to duplex ultrasonography, we wanted to assess our ability to identify deep venous thrombosis on ultrasound. Thirty-eight patients were investigated for suspected deep venous thrombosis by venography and...

The purpose of this article is to review the spectrum of image-based diagnostic tools used in the investigation of suspected deep vein thrombosis (DVT). Summary of the experience gained by the author as well as relevant publications, regarding vein imaging modalities taken from a computerized database, was reviewed. The imaging modalities reviewed include phlebography, color Doppler duplex ultr...

The purpose of this paper is to present a new, possibly preferable method for cavernous sinus and orbital venography, by retrograde catheterization from the arm, With this procedure, good opacification of cavernous sinus may be offered also in patients who have heart diseases, This procedure can be tolerated with minimal discomfort. The patterns of the caverneus sinus are demonstrated in those ...

Introduction: Intravenous leiomyomatosis (IVL) is a rare histologically benign smooth muscle tumor that often originates form uterus and common iliac vein, sometimes extends to the right heart. case report: A rare case diagnosed in catheter-based contrast venography with a pathological finding is described, together with a comparative analysis of all the previous published cases. conclusion: In...

Introduction MR venography (MRv) has an important role in diagnosis of venous diseases. Unlike x-ray or CT venography, MRv produces venographic images without any ionizing radiation. Obtaining venographic image with low noise and high contrast is clinically important for diagnosis of vascular diseases based on MRv. It has been reported that the best venography can be acquired at TE=28ms for vei...

OBJECTIVE Our objectives were to ascertain whether CO2 can be used as a contrast agent in venography during percutaneous vertebroplasty and to evaluate whether it might be capable of replacing nonionic iodinated contrast agents. CONCLUSION Intraosseous venography with CO2 contrast agent was slightly inferior to iodine venography in terms of its ability to visualize the vertebral bodies and pe...

Introduction: To date, conventional venography remains the gold standard for morphologically assessing the veins of the lower extremities. The required administration of iodinated contrast is associated with complications including anaphylaxis, nephrotoxicity as well as venous thrombosis. MR-venography based on TOF techniques has thus been advocated as an attractive non-invasive alternative par...
