Key result
Noninvasive tests like ultrasonography and impedance plethysmography can guide clinical management in 75% to 80% of patients suspected of having deep vein thrombosis, replacing venography.

May reduce venography use in most suspected DVT cases; leaves open prospective validation against modern standards.
What is the clinical utility and accuracy of noninvasive diagnostic tests compared to venography in patients suspected of having deep vein thrombosis?
Ultrasonography should be considered the diagnostic standard for symptomatic DVT, with impedance plethysmography as an acceptable alternative, reducing the need for venography.
H. Brownell Wheeler (1994) conducted a review in Deep vein thrombosis (DVT). Noninvasive diagnostic tests (ultrasonography, impedance plethysmography) vs. Venography was evaluated. Noninvasive tests like ultrasonography and impedance plethysmography can guide clinical management in 75% to 80% of patients suspected of having deep vein thrombosis, replacing venography.
