Please explain in simple but detailed terms how to safely rule out dvt.

Depends: Dvt can be asymptomatic. Normal d- dimer suggests no active clotting. Duplex ultrasound of lower extremities has generally replaced x-ray- venogram and is quite effective. There are some other isotope studies which are rarely done.

Hi, Venous ultrasound is the standard imaging test for anyone suspected of having deep venous thrombosis (DVT)/blood clot. This exam can be performed at almost any radiology office or department. An US tech will perform the exam for you. A radiologist will interpret the results. The duplex ultrasound is very reliable especially for proximal (thigh) clots.
