Overview
Venous thrombosis in the proximal deep veins is responsible for more than 90% of the pulmonary embolisms. Some of the investigators have suggested combined use of CT PE protocol and CT scan venography in cases of suspected DVT and PE.[1] However, it is not done routinely in clinical settings because of certain limitations:
- Side effects of IV contrast administration
- Expensive modality
Uses
It may be considered and is preferred over contrast venography as there is no need to cannulate the foot veins, in the following setting:
- Compression ultrasonography is impractical because of excessive swelling, edema or leg cast, or nondiagnositc.
