Interpretation of these echoes can sometimes be quite difficult and usually requires knowledgeable and experienced specialists. There exist other methods of displaying the ultrasonic test...

Diagnosis was based on clinical probability assessment, plasma D-dimer testing, then sequential testing to include lower limb venous compression ultrasonography, ventilation perfusion lung scan, and chest multidetector CT (MDCT) imaging. METHODS We included 321 consecutive patients presentin...
