Diagnostics of this pathology might include advanced MR venography, direct microcatheter venography with manometry, 3D catheter angiographic studies, three-dimensional rotational venography (3D-RV), cone-beam rotational angiography (3D-RA), also CT venography or MRI scans with contrast with would potentially show obstruction.
Computed tomography, with radiocontrast in the venous phase (CT venography or CTV), has a detection rate that in some regards exceeds that of MRI. The test involves injection into a vein (usually in the arm) of a radioopaque substance, and time is allowed for the bloodstream to carry it to the cerebral veins – at which point the scan is ...
Post mortem CT angiography for medicolegal cases is a method initially developed by a virtopsy group. Originating from that project, both watery [16] and oily [17] solutions have been evaluated. While oily solutions [17] require special deposition equipment to collect waste water, watery [16] solutions seem to be regarded as less problematic ...
The condition can be diagnosed with testing, including a pelvic ultrasound and a type of X-ray, called a CT venogram, that shows how well blood is moving through the veins, according to the Center ...
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography—the visualization of arteries and veins—throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls ...
An MRI using flow parameters and an MR venogram are more sensitive than a CT scan and are the imaging studies of choice to diagnose cavernous sinus thrombosis. Findings may include deformity of the internal carotid artery within the cavernous sinus, and an obvious signal hyperintensity within thrombosed vascular sinuses on all pulse sequences.
The imaging of venous blood with SWI is a blood-oxygen-level dependent (BOLD) technique which is why it was (and is sometimes still) referred to as BOLD venography. Due to its sensitivity to venous blood SWI is commonly used in traumatic brain injuries (TBI) and for high resolution brain venographies but has many other clinical applications.
On CT scans, brain parenchymal hemorrhage that does not confined to specific arterial territory along with hyperdense appearance on dural venous sinuses raises the suspicion of DVST. Further evaluation with CT venography, MR venography, and post gadolinium MRI provides accurate diagnosis of venous thrombosis and follow-up after treatment.
