Duplex US evaluation is the diagnostic study of choice for venous thrombosis. Thrombosed veins may appear thickened or inflamed on US, but the most accurate diagnostic finding is a lack of compressibility of the vein using the scan head (see the image below). An experienced sonographer should be able to diagnose superficial thrombophlebitis with a high sensitivity and specificity. [20]
