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.
Cerebral edema and venous infarction may be apparent on any modality, but for the detection of the thrombus itself, the most commonly used tests are computed tomography (CT) and magnetic resonance imaging (MRI), both using various types of radiocontrast to perform a venogram and visualise the veins around the brain.

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 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 ...
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.
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 ...
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 ...
When faced with unexpected expenses of $1,000 or more, 1 out of 5 U.S. adults (21 percent) would do the same, according to Bankrate’s 2024 Annual Emergency Savings Report. As you can see, it’s ...
