Overview
A number of invasive and non-invasive approaches are possible. Duplex Ultrasonography, due to its high sensitivity, specificity and reproducibility, has replaced venography as the most widely used test in the evaluation of the disease.
Imaging the leg veins
- Impedance plethysmography[1]
- Doppler ultrasonography
- Compression ultrasound scanning of the leg veins, combined with duplex measurements (to determine blood flow)
can reveal a blood clot and its extent (i.e. whether it is below or above the knee).
Examples
- Example #1: CT images: DVT at left leg
- Example #2: 2D TOF GRE MRV images: Bilateral deep vein thromboses
