CT of the Fingers is an imaging exam focused on the detailed assessment of the bone and joint structures of the fingers of the hand or foot. It is especially useful when X-ray does not fully clarify fine fractures, joint injuries or post-traumatic changes.
What is CT of the Fingers and what is it for?
CT of the Fingers is a computed tomography scan that generates high-resolution images of the phalanges, interphalangeal joints and adjacent tissues.
This exam is often indicated when precise characterization of fracture lines, bone consolidation or surgical planning is required.

The exam lasts on average between 5 and 15 minutes.
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.

CT of the Fingers is an exam that can detect various bone and joint changes, such as:
- Occult or complex fractures of the fingers;
- Joint dislocations and subluxations;
- Degenerative changes (osteoarthritis) and inflammatory erosions;
- Ligament injuries and associated bone avulsions;
- Bone tumours and cysts;
- Signs of bone infection (osteomyelitis) or post-operative changes;
- Among others.
In which cases is it indicated?
CT of the Fingers is generally requested by the physician in situations such as:
- Trauma with suspected finger fracture not clarified by X-ray;
- Persistent pain and swelling without a defined diagnosis;
- Rheumatologic diseases with suspected erosions;
- Pre-operative assessment and planning of hand/foot surgery;
- Post-operative follow-up or assessment of bone consolidation;

CT of the Fingers with Contrast
CT of the Fingers is usually performed without contrast. In selected cases, such as suspected infection, masses or tumours, intravenous contrast may be administered. The injection may cause a transient sensation of warmth or a metallic taste. In these cases, fasting for 4 hours is usually required (you will be informed at the time of booking).
