When computerized tomography,  CT scan is needed:

Computerized tomography is a sophisticated noninvasive imaging technique combining  a special equipment with x-ray to create detailed pictures of structures inside of the body, in order to obtain diagnostic information. Computerized tomography is used to investigate different parts of the body such as thorax, abdomen, pelvis, legs and can take pictures of organs such as the liver, pancreas, intestine, kidneys, adrenals, lungs, and heart. Also Computerized tomography can provide computerized  information regarding blood vessels, bones and spine.


How a computerized tomography , CT, works:

During Computerized tomography , CT, at the doctor indication , may be used a  iodized substance (contrast dye) to better visualize anatomical structures and organs investigated. This contrast  dye can be used to investigate the permeability of blood vessels ,  tumors or other diseases. The substance can be administered intravenously or orally.


Computerized tomography, CT scan side effects:

Computerized tomography is painless, but some patients may feel uncomfortable inside the cylinder. If it is necessary to administer a sedative or  a contrast substance, then it will be made an intravenous infusion. The administration of contrast  substance may cause a feeling of warmth and may be as metallic taste in the mouth. Some patients may have nausea or headaches. Regardless of sensations, the patient will have to notify the physician or technician.  The risk of problems while performing a Computerized tomography is small but the contrast  substance can cause an allergic reaction. If the patient has diabetes and is being treated with metformin, the contrast substance can cause some problems . The doctor will recommend to stop the procedure  and will be informed of the number of exposures to radiation before conducting the investigation.  Computerized tomography investigation CT  has contraindications such as pregnancy, allergy to iodinated substances, kidney failure and thyroid disease.


Computerized tomography, CT scan preparation:

If the CT examination requires intravenous administration of contrast material , do not eat 4-6 hours before examination. To examine the abdomen and pelvis, patients will be asked to drink the contrast substance or water before examination (0.5 – 2 liters) about 1-2 hours before the investigation. Patients who have kidney failure will not receive intravenous contrast substance. Patients with diabetes will have to inform the  doctor before examination. Patients with thyroid disorders, hepatitis, cirrhosis or known allergies to iodine will have to inform the radiologist about these medical conditions. The patient will empty the bladder 30-40 min before examination.  Women who have breastfeeding and perform a CT with contrast can breastfeed again at 24-48 hours after examination. Pregnant women will not be subjected to Computerized  tomography investigation unless it is absolutely necessary. In this case, the patient could perform an MRI exam as an alternative.
