How high is D dimer in DVT?
High plasma D-dimer level >2.0 μg/ml was found in 68% of patients with DVT and 45% without DVT (P < 0.05). Therefore, high D-dimer level greater than 2.0 μg/ml showed 68% sensitivity, 55% specificity, 60% accuracy, 50% positive predictive rate and 72% negative predictive rate in the detection of early DVT after TKA.
Are venous dopplers accurate?
It can also show the movement of blood within blood vessels. Compared to venography, which requires injecting contrast material into a vein, venous ultrasound is accurate for detecting blood clots in the veins of the thigh down to the knee. In the calf, because the veins become very small, ultrasound is less accurate.
Will a CT scan show a blood clot in the leg?
CT scan or computed tomography scan is a great way to detect these kinds of dangerous blood clots in our body. There are different types of CT scans. The CT venography allows doctors to have a clear image of veins, especially the veins in the legs.

How is DVT diagnosed?

What is the difference between an ultrasound and a Doppler?
How the Test is Performed. A duplex ultrasound combines: Traditional ultrasound: This uses sound waves that bounce off blood vessels to create pictures. Doppler ultrasound: This records sound waves reflecting off moving objects, such as blood, to measure their speed and other aspects of how they flow.
