CT scan of the joint

CT (computed tomography) is a diagnostic method that uses X-rays to create detailed, three-dimensional images of internal organs and structures. During the scanning process, the patient is positioned on a table that gently moves through a cylindrical device through which X-rays pass from multiple angles. A special program then combines the obtained images to produce a three-dimensional image of the body’s interior. CT is used in diagnosing various health problems, including detecting tumors, traumatic injuries, blood clots, and other conditions. It is important to note that CT uses X-rays, which involve a certain radiation dose, so its application must be carefully considered in relation to benefits and risks.

CT of bones or joints can be used to guide a doctor or surgeon during procedures such as biopsy. They are precise and sensitive in detecting small bone fractures, periosteal reactions (bone infections and inflammation), and degenerative bone diseases. They are important in planning certain types of therapy and surgeries, as well as in follow-up treatment to determine whether the patient’s body is responding to treatment. CT examination can be used to detect cysts or infections in the body. They can also identify bone structures within the body and precisely measure bone density. CT scanning is often used for rapid patient assessment after an accident to identify traumatic internal injuries.

A joint is an important part of the body where two or more bones meet to enable movement. Almost every bone in the body meets at least one other bone at a joint. The shape of the joint depends on its function. Generally speaking, the more movement possible through a joint, the greater the risk of injury to it. This is because a greater range of motion reduces the strength of the joint. Joints are divided into:

Immovable – two or more bones are in close contact, but no movement can occur – for example, skull bones. Skull joints are called sutures.

Slightly movable – two or more bones are held together so tightly that only limited movements are allowed – for example, vertebrae.

Freely movable – most joints in the human body are of this type. Movement is the purpose of the joint.

CT of joints at Atrium Polyclinic Sarajevo

In the Atrium Polyclinic, CT of joints is performed on a modern CT scanner Toshiba Aquilion Prime 160 slice. CT of joints on the Toshiba Aquilion 160 slice device has several advantages compared to other CT devices:

• High resolution: Toshiba Aquilion 160 slice has high image resolution.
• Scanning speed: Thanks to the large number of detectors (in this case 160 slices), scanning is faster than on devices with fewer “slices”. This reduces the risk of motion artifacts, improves image quality, and reduces patient radiation exposure.
• Low radiation dose: Advanced image processing techniques, such as iterative reconstruction and the use of low-dose protocols, reduce the radiation dose needed to obtain high-quality images.
• Accurate diagnostics: High resolution and scanning speed enable precise diagnostics.
• Patient comfort: Faster scanning reduces the time spent in the scanner, improving patient comfort and reducing anxiety.

CT joint examination, when is it needed?

While conventional X-ray imaging can capture bone structure, it does not show soft tissue clearly enough. Joints are complex structures consisting of soft tissue and bones that support body movement. Therefore, a more advanced form of imaging is needed. CT scanning is the preferred method for imaging joints because it clearly records very detailed images of bone structure. When it comes to CT examination of a joint, the position of your body will depend on whether the upper or lower joint needs to be scanned.
