A CT (computed tomography) scan is a type of medical imaging test that uses X-rays and advanced computer technology to create detailed images of the bones, muscles, and other tissues in the foot. A foot CT scan can help doctors diagnose a wide range of foot and ankle conditions, such as fractures, tumours, arthritis, and deformities.
During a foot CT scan, the patient lies on a table that slides into a machine that takes multiple X-ray images of the foot from different angles. The X-ray images are then processed by a computer to create detailed cross-sectional images of the foot that can be viewed on a monitor or printed out.
Foot CT scans are typically performed on an outpatient basis and can take anywhere from 15 to 45 minutes, depending on the complexity of the scan. Before the scan, the patient may be required to remove any metal objects from their body and change into a hospital gown. After the scan, the patient can usually resume normal activities immediately. The results of the scan are typically available within a few days and will be reviewed by a doctor or radiologist.
