(Redirected from Blood/Venous imaging)
- Superficial femoral vein is a deep vein
- Venograph is the gold standard, but doppler ultrasound is what is used.
- Above-knee is more useful than below knee imaging, since below-knee occlusions are not usually treated
- Fibrinogen scanning is less useful because it is most sensitive/specific below knee
- Westermarks sign (Westermark described focal oligaemia distal to the occluded vessel)
- Hamptons hump (When focal consolidation occurs in the costophrenic angle, this is deemed a Hampton's hump.)
- For PE, the gold standard is pulmonary angiography
