Computed tomography / CT scan

Computed tomography (CT) is a diagnostic method that uses X-rays to obtain cross-sectional images of the inside of the body.

The main components of a CT scanner are an X-ray tube and detectors mounted on opposite sides of a circular gantry. The X-ray tube generates radiation that passes through the body of the patient lying inside the scanner and is received by the detectors. The X-ray beam passing through the body is absorbed to different degrees by different tissues. The detectors measure the level of X-ray absorption, and on this basis a cross-sectional image of the body is created. Bones, which absorb radiation most strongly, appear white, while other tissues appear in various shades of grey.

Computed tomography is characterised by high spatial resolution. Two- and three-dimensional images of the examined structures can be obtained.

Scope of computed tomography examinations

Computed tomography is used to diagnose complex bone injuries that are difficult to detect on X-ray, such as:

• visualisation and detailed assessment of complex fractures prior to planned surgery,
• assessment of post-operative complications (e.g. evaluation of bone union disorders, inflammatory changes, destabilisation of osteosynthesis),
• evaluation of completed bone osteosyntheses,
• assessment of the correct alignment of bone structures,
• assessment of acquired or congenital bone deformities,
• assessment of extra-articular calcifications,
• assessment of limb/bone rotation,
• assessment of changes in bone structure – inflammation, tumours,
• assessment of intra-articular structures after intra-articular administration of contrast medium – CT arthrography.

CT examinations are also performed on patients with contraindications to MRI (e.g. patients with metal implants, cardiac pacemakers, etc.).

We also perform CT arthrography examinations.
