DVT: It woulld be very unusual for 3 us to miss dvt. Venous us is quite sensitive and specific for diagnosis of both DVT and superficial thrombosis. Why do you need to repeat three us of leg. Do you have any symtoms such as leg swelling/pain? Hopely radiologist agrees with me. I haven't seen any.

Very unlikely: Ultrasounds of the lower extremity are fairly sensitive in picking up dvt's. It is highly unlikely that one would have a DVT that is not showing up after 3 ultrasounds.

Ultrasound and DVT: A venous duplex ultrasound is the most accurate test to evaluate for DVT between the lower calf and the groin. The accuracy of the test usually depends on the machine used and the expertise of the ultrasonographer and the interpreter of the exam. 3 negative ultrasounds is certainly strong evidence that no clot would exist between the areas examined. Clots, however, can occur in other areas.
