Advanced diagnostic imaging and Radiology services are offered at Molecular Diagnostics and Therapy, a NABL & NABH-accredited diagnostic centre, including CT Lower Limb Angiography. This is a specialised test that utilises the power of the contrast dye to help doctors evaluate the blood vessels that feed the legs, which might narrow or block, decreasing circulation, or may develop an aneurysm or be damaged. The scan is used to create detailed pictures of lower limb arteries to aid in assessment, planning of treatment, and further vascular investigations as clinically indicated.

About CT Lower Limb Angiography

In some cases (depending on the scan protocol), the procedure is a complex imaging test where the doctor can get information from different blood vessels. Depending on the scan protocol, the examination may cover the pelvic arteries and arteries of the thighs, knees, lower legs, and feet. It can assist in identifying blockages, narrowing, abnormal widening, or damage to the legs that occurs when the blood flow decreases in patients reporting leg pain on walking; in individuals with a low pulse (carotid or peripheral); cases in which wounds do not heal well; patients with a possible peripheral arterial disease; and when there has been an unusual decrease in blood flow.

What is CT Lower Limb Angiography?

CT Lower Limb Angiography is a CT imaging technique that also involves an injection of a material into the blood vessels in order to obtain detailed imaging of the blood vessels that supply blood to the lower limbs. The requested protocol may be used to examine the pelvic and leg arteries (femoral, popliteal and/or tibial). It will enable the doctor to see if the blood vessels are being narrowed either by trauma or some deposition of blood. The scan can help identify arterial narrowing due to atherosclerotic plaque, arterial occlusion, traumatic injury, and selected vascular abnormalities.

Common Reasons for CT Lower Limb Angiography

• Leg pain while walking: Evaluation of symptoms that may indicate reduced arterial blood flow.
• Suspected peripheral arterial disease: Assessment of narrowing or blockage in the arteries supplying the legs.
• Poor circulation: Investigation of reduced blood supply, cold feet, or diminished peripheral pulses.
• Non-healing wounds or ulcers: Evaluation of arterial circulation when impaired blood flow may affect wound healing.
• Sudden limb pain or suspected arterial blockage: Assessment of possible acute vascular obstruction when clinically indicated.
• Vascular injury: Evaluation of suspected arterial damage following trauma or an accident.
• Suspected aneurysm: Examination of abnormal widening of an artery.
• Pre-procedure planning: Mapping of arterial anatomy before selected vascular interventions or surgery.
• Post-treatment assessment: Evaluation of treated arteries, stents, or bypass grafts when requested by the treating clinician.
• Suspected vascular abnormalities: Investigation of congenital or acquired abnormalities involving the arteries of the lower limbs.

Conditions Evaluated

Arterial Stenosis and Occlusion

The scan can be employed to pinpoint the location of narrowed or even perhaps blocked arteries. The results might provide clues to symptoms of insufficient circulation to the legs and feet.

Aneurysms

Additionally, CT imaging shows if the arteries in the legs are enlarged and can help identify blood vessel anatomy and size in the vicinity of these arteries.

Acute Vascular Injury

Examination of the trauma can search for some indications of disruption, narrowing, blockage, or leakage of the dye in the artery (depending on the type of trauma and when it occurred).

Vascular Abnormalities

It can be useful to evaluate the source of disorders of the lower limb artery in congenital and acquired abnormalities where normal anatomy is absent, and there are a few abnormal vascular connections.

Book Your CT Lower Limb Angiography

If your doctor suggested you might want to have an appointment for CT Lower Limb Angiography, then come to Molecular Diagnostics and Therapy. Bring any medicines, previous medical photos, and medical history, including any previous vascular surgery, stents, bypass surgery, etc. Tell the radiology personnel if you have had any reactions to the IV material in the past, kidney or thyroid disease, or are using any medicine that could have an impact on the scan. Clinically appropriate, renal function testing may be ordered.
