Computed tomography CT
Computed tomography is a high-technology imaging method. Digital images obtained by multislice CT are more detailed than conventional radiography. The modern Siemens multislice computed tomography scanner is characterized by high scanning speed, and its advanced software capabilities allow for three-dimensional multiplanar and volumetric image reconstruction.
CT enables the detection of pathological processes in the brain, abdominal and thoracic organs, retroperitoneal space, pelvic vessels, paranasal sinuses, skeletal bones and joints, spine, and numerous other structures. It also allows for determining the nature, extent, and vascularization of these processes.
Intravenous bolus CT angiography is performed to detect tumors, and vascular anomalies, and assess the nature of blood supply to already identified tumors and their relationship with major vessels, in cases of portal hypertension, and for dangerous complications such as pulmonary embolism.
Non-bolus intravenous contrast enhancement is used for examining diseases of the kidneys, ureters, bladder, tumors, and urinary flow disorders.
Oral contrast administration is used as a necessary preparation for small and large intestine examinations and pelvic organ studies.
Virtual colonoscopy with intestinal contrast enhancement is performed for colon examination using an enema technique.
CT scans can be performed for the following anatomical regions and structures:
- Orbital region
- Brain
- Paranasal sinuses
- Maxillofacial area
- Neck organs
- Cervical spine
- Thoracic organs (lungs, mediastinum)
- Retroperitoneal organs
- Pelvic organs
- Thoracic spine
- Lumbosacral spine
- Upper extremities (including joints)
- Lower extremities (including joints)
- Small and large intestines
