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 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
