Ultrasonographic image of a deep vein thrombosis (DVT).
Sequential images demonstrate treatment of iliofemoral deep venous thrombosis due to May-Thurner (Cockett) syndrome. Far left: View of the entire pelvis demonstrates iliac occlusion. Middle left: After 12 hours of catheter-directed thrombolysis, an obstruction at the left common iliac vein is evident. Middle right: After 24 hours of thrombolysis, a bandlike obstruction is seen; this is the impression made by the overlying right common iliac artery. Far left: After stent placement, image shows wide patency and rapid flow through the previously obstructed region. Note that the patient is in the prone position in all views. (Right and left are reversed.)
Ventilation-perfusion scan. Left image: Posterior view of normal findings on ventilation-perfusion scan. Right image: Posterior view of a perfusion scan that reveals a perfusion defect in the left upper quadrant. The defect in the middle of the image is due to the position of the heart.
Helical computed tomography scan of the pulmonary arteries. A filling defect in the right pulmonary artery is present, consistent with a pulmonary embolism.
