This test may be recommended to evaluate blood vessels, bones, and soft tissue of the lower extremities for any abnormalities or signs of disease, such as tumors, infections, blood clots, or vascular disease.
When this test is required
CT Lower Limb with and without contrast may be requested by a doctor or other healthcare provider when a patient is experiencing symptoms or has an abnormality that requires further evaluation.
What the Test Detects
CT Lower Limb with and without contrast uses X-rays and a contrast dye to produce detailed images of the lower extremities, including bones, muscles, blood vessels, and soft tissue. The contrast dye helps to highlight the blood vessels and allows the radiologist to better evaluate the blood flow and detect any abnormalities.
Preparation for the Test
Before the procedure, patients may be asked to avoid eating or drinking for a few hours. They should inform their doctor if they have any allergies or are taking any medications. Patients may also be asked to remove any metal objects, such as jewelry or clothing with metal fasteners, as these can interfere with the imaging.
Sample Requirements
No sample is required for CT Lower Limb with and without contrast.
Additional Notes
CT Lower Limb with and without contrast is considered a safe and relatively non-invasive procedure. However, it does involve exposure to radiation and the contrast dye, which may cause an allergic reaction in some patients. Patients should inform their doctor if they are pregnant or may be pregnant.
