Indications for the CT scan
The decision on the type of examination to be undertaken, in cases of both private examinations and those reimbursed by the NFZ, is made by the referring physician after the patient’s physical examination and after taking the patient’s medical history. The method of examination is selected each time by the radiologist on the basis of a referral letter submitted by the patient, taking into account the current medical standards, and on the basis of the latest knowledge relating to the selected diagnostic issue and an analysis of the test results to date.
The radiologist performing the scan may, at the patient’s request, provide information on the procedure, possible modification (on the basis of the obtained medical history) and possible side effects. As a matter of routine, information on the procedure is passed to the patients by the electro-radiology technician just before the start of the procedure. The radiologist conducting the procedure decides on the intravenous administration of the contrast medium. The decision is made individually on the basis of medical knowledge on the side effects of the use of intravenous contrast media, including information on diagnostic problems as well as the patient’s current health status.
Current guidelines concerning the application of intravenous contrast media in imaging diagnostics are available on the ESUR (European Society of Urogenital Radiology) website.
