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.
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 ...
Nutcracker syndrome is diagnosed through imaging such as doppler ultrasound (DUS), computed tomography (CT), magnetic resonance imaging (MRI), and venography. [12] The selection of the imaging modality is a step-wise process. DUS is the initial choice after clinical suspicion based on symptoms.
Venography (also called phlebography or ascending phlebography) is a procedure in which an X-ray of the veins, a venogram, is taken after a special dye is injected into the bone marrow or veins. The dye has to be injected constantly via a catheter, making it an invasive procedure.
