Review of the current diagnostic techniques for deep vein thrombosis

The objective of this paper is to give an overview of the diagnostic techniques for Deep Vein Thrombosis (DVT) DVT is a disorder that causes blood clots to form in the deep veins. Swelling or Pain of a lower limb is a regular symptoms that affects the deep leg veins. Generally, DVT is one of the most common causes of illness and mortality in the world. It is difficult to diagnose the DVT clinically, and the commonly used laboratory screening is the D-dimer test, which has a high sensitivity with low specificity. As a result, more precise and non invasive diagnostic tools are needed to identify and properly localize DVT. Also, the painless identification of DVT is possible with noninvasive diagnostic tools. Though imaging techniques are commonly utilized to identify and localize the DVT, still they are very expensive. The study emphasizes that present diagnosis techniques and instruments are less sensitive; sensitivity is typically raised through sequential processes and the integration of additional approaches. Hence, more diagnosis methods and tools need to be developed for the accurate identification of DVT. As well, ideal properties like sensitivity, specificity, cost, and risk must be considered.
