Overview
A number of invasive and non-invasive approaches are possible.[1] Doppler 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 Techniques
- Impedance plethysmography[2]
- 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
