Q: What is one simple (and probably only) advantage of impedance plethysmography over compression ultrasonography in the diagnosis and follow-up of Deep Venous Thrombosis (DVT)?


Answer:  Impedance plethysmography normalizes relatively more quickly after a previous episode of DVT, and can be more helpful in patients with recurrent DVT or in the follow-up of present DVT.
