Purpose of the Test

A CT scan of the lower limb without contrast is typically done to diagnose or evaluate conditions that affect the bones, joints, and soft tissues of the leg, foot, or ankle. Some of the conditions that may require this test include fractures, tumors, arthritis, infections, or circulation problems.

When this test is required

A CT lower limb without contrast (single region) may be requested by a doctor or specialist when a patient is experiencing symptoms such as pain, swelling, or limited range of motion in the lower extremities. It may also be ordered as part of a routine screening for certain conditions, such as osteoporosis.

What the Test Detects

A CT lower limb without contrast (single region) is a medical imaging test that uses X-rays and computer technology to create detailed images of the bones, muscles, and tissues of the lower extremities (including the hips, thighs, knees, calves, and ankles) without using any contrast material.

Preparation for the Test

Generally, no specific preparation is required for a CT scan of the lower limb without contrast. However, patients may be advised to wear loose and comfortable clothing and avoid wearing metal objects or jewelry on the legs, as these can interfere with the scan results. Patients may also be asked to remove any clothing or objects that could interfere with the scan, such as belts, piercings, or hearing aids. It is important for patients to inform their healthcare provider if they have any allergies, medical conditions, or are pregnant before undergoing a CT scan.

Sample Requirements

The sample required for this test is simply the patient’s body. No additional samples such as blood or urine are necessary.

Additional Notes

It is important to inform your doctor and the radiology staff if you have any allergies or previous reactions to contrast material or iodine, as this test does not use contrast but may require it if the doctor decides so. Additionally, pregnant women or patients with kidney disease may not be good candidates for this type of imaging and may require a different imaging modality.
