Answer

MRI has increasingly been investigated for evaluation of suspected DVT. Limited studies suggest the accuracy approaches that of contrast venography. MRI is the diagnostic test of choice for suspected iliac vein or inferior vena caval thrombosis when CT venography is contraindicated or technically inadequate. Radiolabeled peptides that bind to various components of a thrombus have been investigated. The cost of the tests and the inability to visualize the anatomy of the area of involvement (which many clinicians prefer) has lead to the underuse of scintigraphy.

Additionally, note that imaging modalities, techniques, and findings may be specific to the upper extremities and lower extremities.
