Getting tested for deep vein thrombosis, or DVT, can disrupt a patient’s whole day. Typically, one of the first methods a clinician uses to diagnose the condition is an ultrasound in order to see the blood vessels in a patient’s legs and assess blood flow. From check in to check out, the procedure can take several hours. For rural patients, who often drive long distances to reach medical practices where the necessary equipment and personnel are available, the process is even more onerous.
