What is a CT scan?
A CT scan is a modern X-ray procedure that captures images of the body layer by layer. While conventional X-rays provide only a two-dimensional image, computed tomography scans produce numerous cross-sectional images that are then combined to form a detailed picture.
This high image resolution makes it possible to accurately assess even deep-seated structures. Bones, internal organs, lungs, and blood vessels in particular, can be visualized exceptionally well with a CT scan.
Modern CT systems operate extremely quickly and provide a large amount of diagnostically relevant information in a short amount of time. This makes it possible to reliably diagnose even complex conditions.
For which areas of the body is a CT scan appropriate?
Computed tomography scans are used in nearly all medical specialties. The following are particularly common areas of examination:
-
Skull and brain -
Spine
-
Chest and lungs
-
Abdomen and pelvis
-
Bones and joints
-
Blood vessels as part of a CT angiography
Depending on the symptoms, the examination can be focused on a single area of the body or on several areas at the same time.
In what cases is a CT scan performed?
A CT scan is often recommended when medical conditions or injuries need to be diagnosed as quickly as possible and/or when particularly detailed images are required.
Reasons for a CT scan may include:
-
Fractures
-
Spinal injuries
-
Lung diseases
-
Abdominal symptoms
-
Vascular diseases
-
Tumor diagnosis
-
Surgical planning
-
Follow-up care after treatment
Which imaging modality provides the best diagnostic results in each individual case always depends on your symptoms and the clinical question at hand.
