Overview
CT scan is not a routine test for the diagnosis of deep vein thrombosis (DVT). CT scan venography can be considered for the diagnosis of DVT when ultrasonography is either impractical or non-diagnostic.[1]
CT
Uses
- CT scan might be used for diagnosis of DVT when compression ultrasonography is impractical in cases of excessive swelling, edema, or a leg cast, or when the ultrasound in non-diagnostic.[1]
- CT scan is preferred over contrast venography as there is no need to cannulate the foot veins.
Limitations
CT scan is not done routinely in clinical settings because of certain limitations:
- Side effects of IV contrast administration
- Expensive modality
Examples
- CT images: DVT at left leg
