Deep Vein Thrombosis DVT Scan
A deep vein thrombosis (DVT) scan is the most common and effective method for detecting blood clots in the deep leg veins. This ultrasound is designed to assess the deep veins and their junctions with superficial veins in the affected leg to check for DVT.
Veins that are usually assessed with a DVT scan include:
- Femoral vein
- Saphenofemoral junction
- Saphenopopliteal junction
- Popliteal vein
- Deep calf veins, including anterior tibial vein, posterior tibial vein, and peroneal veins.
What Can a DVT Scan Detect?
A DVT ultrasound scan helps identify deep vein thrombosis —a blood clot forming in the deep veins, typically in the legs. It also helps in:
- Detecting blockages in blood circulation due to a clot
- Confirming DVT presence in the leg
- Assessing symptoms such as leg pain, inflammation, or discolouration
Ultrasound is the primary imaging technique for visualising blood flow and detecting clots. However, in certain situations, advanced imaging techniques, including CT scans or venography, could be required for more assessment.
What Does the DVT Scan Involve?
You will need to uncover the area being examined during the procedure. Therefore, we recommend wearing loose, comfortable clothing.
To improve image clarity, some ultrasound gel will be applied to your skin, and a handheld ultrasound probe will be placed over the area and moved around. This produces real-time images displayed on the ultrasound monitor, which will then be analysed so as to determine if there is any problem.
The DVT scan is entirely painless and normally lasts 10 to 15 minutes. Once it is completed, you will receive a report of the findings and have the chance to discuss them with our specialist.
