Computed tomography scan

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

Duration: 15-30 minutes.
Anesthesia: not required.

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.
