What is the spiral computed tomography scan?
It is a highly accurate radiography method based on the ability of body tissues to absorb x-rays. During the scan, both the bed with a patient and CT scanners inside the gantry are moving. As a result, the x-ray source moves spirally around the patient.
The method is based on calculating the difference that each tissue shows when stopping X-rays. This difference is picked up by special detectors and is constantly transmitted to a computer. As a result, there is a number of image slices that can be transformed into a 3D image with the help of sophisticated computing.
Spiral computed tomography is used to diagnose a wide range of diseases. The scan is ordered when there are bone and internal organs damages, a suspicion of tumors, blood vessel abnormalities, etc.
CT with a contrast agent
A type of computed tomography that is used to scan abdominal organs, blood vessels, etc. For this test, a contrast agent is injected into the patient’s bloodstream.
CT advantages
- The possibility to scan several body parts.
- Minimal x-ray exposure.
- The ability to obtain a detailed image that helps to see the smallest changes in the structure of internal organs, tissues, and blood vessels.
- The possibility to scan complex areas of a human body – blood vessels in the brain and the structure of the bronchopulmonary system.
What is it used for?
- Head – to identify inflammatory processes, post-injury complications, hydrocephalus, tumors, blood vessel abnormalities, and other circulatory disorders.
- Small pelvis – to identify kidney stone disease, benignant and malignant tumors, injuries, bone, tissue, and blood vessel abnormalities.
- Abdominal cavity – to diagnose liver, adrenal gland, spleen, urinary tract, and other organs' diseases.
- Thorax – to diagnose the diseases of cardiovascular and respiratory systems in order to detect pneumonia, tuberculosis, cancer, as well as abnormalities in the bronchus, lungs, cardiac muscle, blood vessels.
- Neck, spine – the analysis of injuries, diseases of a spinal column, and surrounding vessels.
- Joints, bones – to identify the abnormalities of inflammatory and traumatic origin, their complications, tumors.
Indications
- Cancer diagnosis: to identify tumors of the internal organs, bones, soft tissues.
- To determine the stage of cancer, identify metastases, obtain the data on the tumor size and its spreading.
- Injuries and their consequences: bleeding, hematoma, ruptured organs, internal organs damage, bone fractures and fissures.
- Changes that are visible in x-ray, ultrasound and other diagnostic tests.
- To control the effectiveness of the treatment after beam or chemotherapy.
- To examine a body part or an organ before surgery.
- To monitor the tissues after surgery.
About the procedure
What to expect during a CT-scan?
This test is not done at Kivach Clinic. Should a patient need a CT-scan, he/she will be transported to a partner medical institution.
The patient removes all metal objects from his/her body - earrings, watches, bracelets, rings, necklaces, etc. It is possible to have a scan if the patient has a tooth crown.
A CT scanner is located in a separate room. The patient lays down on a table. Nurses provide all necessary instructions. If it is a contrast CT scan, the patient takes a special contrast material orally or has it injected.
The scan is done in motion, while the examined area passes through the scanner. As a rule, the scanning does not take longer than 30 minutes and does not produce any loud noises.
The results and a preliminary medical conclusion are ready within a couple of minutes after the scanning is over.
The information obtained by the scan will be sent to Kivach Clinic so that the doctor can analyze it and make a final diagnosis.
Contraindications
- Metal objects in the body (prostheses, fragments), pacemaker, artificial heart valves, etc.
- Hypersensitivity to contrast material (iodine allergy).
- Mental disorders.
- Body weight that exceeds 120 kg.
- Pregnancy.
- Age under 7.
Question-answer
- Is the scan safe?
-

- Is the scan painful?
-
The scan is painless.
- Are complications possible?
-
The scan is not done should there be any contraindications.
- How to prepare for the procedure?
