2. Angiography - Wikipedia

   en.wikipedia.org/wiki/Angiography

   Additionally, damage to blood vessels can occur at the site of puncture/injection, and anywhere along the vessel during passage of the catheter. If digital subtraction angiography is used instead, the risks are considerably reduced because the catheter does not need to be passed as far into the blood vessels; thus lessening the chances of ...

3. Serum-ascites albumin gradient - Wikipedia

   en.wikipedia.org/wiki/Serum-ascites_albumin_gradient

   A high gradient (> 1.1 g/dL, >11 g/L) indicates the ascites is due to portal hypertension, either liver related or non-liver related, with approximately 97% accuracy. [2] This is due to increased hydrostatic pressure within the blood vessels of the hepatic portal system , which in turn forces water into the peritoneal cavity but leaves proteins ...

4. Computed tomography angiography - Wikipedia

   en.wikipedia.org/wiki/Computed_tomography...

   CTA can be used in the chest and abdomen to identify aneurysms in the aorta or other major blood vessels. These areas of weakened blood vessel walls that bulge out can life-threatening if they rupture. CTA is the test of choice when assessing aneurysm before and after endovascular stenting due to the ability to detect calcium within the wall. [3]

5. Vein matching - Wikipedia

   en.wikipedia.org/wiki/Vein_matching

   Unlike some biometric systems, blood vessel patterns are almost impossible to counterfeit because they are located beneath the skin's surface. Biometric systems based on fingerprints can be fooled with a dummy finger fitted with a copied fingerprint ; voice and facial characteristic-based systems can be fooled by recordings and high-resolution ...

6. Intravascular imaging - Wikipedia

   en.wikipedia.org/wiki/Intravascular_imaging

   Intravascular imaging is a catheter based system that allows physicians such as interventional cardiologists to acquire images of diseased vessels from inside the artery. . Intravascular imaging provides detailed and accurate measurements of vessel lumen morphology, vessel size, extension of diseased artery segments, vessel size and plaque characteristi

7. Susceptibility weighted imaging - Wikipedia

   en.wikipedia.org/wiki/Susceptibility_weighted...

   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 ...

9. Magnetic resonance angiography - Wikipedia

   en.wikipedia.org/wiki/Magnetic_resonance_angiography

   Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
