CT of the Foot allows a detailed evaluation of the bones, joints, alignment and adjacent structures of the hindfoot, midfoot and forefoot. It is valuable in trauma, sports medicine and in the study of arthropathies.
What is CT of the Foot and what is it for?
CT of the Foot is a computed tomography scan that provides thin slices and 3D reconstructions of the calcaneus, talus, tarsal bones, metatarsals and phalanges. It is often requested when X-ray and ultrasound are not sufficient to clarify complex injuries.
How much does CT of the Foot cost?
The price of CT of the Foot when performed on a private basis is €100.

How is it performed?
CT of the Foot is performed with the patient lying on a table that slides into the scanner (open at both ends), with the foot immobilised in an appropriate position. The exam lasts about 5 to 15 minutes and generates high-definition images for detailed analysis.
NRD has a latest-generation Philips 128-slice scanner, which provides sharp images with a low radiation dose, ensuring safety and effectiveness in every exam.
What does it detect?
CT of the Foot is an exam that can detect structural and traumatic changes in the feet, such as:
- Occult fractures (e.g. calcaneus, Lisfranc) and complex fracture lines;
- Osteoarthritis, osteophytes and degenerative changes;
- Post-traumatic injuries of the hindfoot and midfoot;
- Bone cysts and tumours;
- Signs of osteomyelitis or infectious complications;
- Deformities and structural misalignments;
- Among others.
In which cases is it indicated?
CT of the Foot is generally requested by the physician in situations such as:
- Trauma with persistent pain and inconclusive X-ray;
- Assessment of complex fractures for surgical planning;
- Study of degenerative or inflammatory arthropathies;
- Suspected bone infection or post-operative complications;
- Monitoring of bone healing and surgical outcomes;
- Assessment of flatfoot/high-arched foot deformities and alignment;
- Among others.
CT of the Foot with Contrast
CT of the Foot is, in most cases, performed without contrast. In suspected infection, tumours or inflammatory processes, intravenous contrast may be used. The injection can cause a transient sensation of warmth or metallic taste. Fasting for 4 hours is usually required (you will be informed at the time of booking).
Preparing for CT of the Foot
| Topic | Guidance |
| Exam prescription (paper copy) | You should bring the exam prescription in paper format. |
| Fasting | If the exam is performed with contrast, you must fast for 4 hours. When the exam is performed without contrast, fasting is not required. |
| Arriving early | Generally, you only need to arrive 15 minutes before the exam, except in cases where oral contrast will be used. In that case, you should arrive 1 to 2 hours before the exam (you will be informed at the time of booking). |
| Previous exams | You should bring any relevant previous exams. |
| Previous medical history | Keep in mind your previous medical history regarding allergies, cardio-respiratory and kidney diseases, and usual medication. |
| Water | If necessary or if you wish, you may drink water. |
NRD will provide you with all the necessary instructions at the time of booking.
Remain still to avoid artefacts on the images.
When and how do you receive the results?
You will receive the CT scan results within up to 7 days after the exam, by email or in paper form at the clinic. On the day of the exam, you will take the CD with the images with you.
