Computerized Axial Tomograghy (CT) scans generate computer-enhanced
x-ray cross sectional views, as well as 3 dimensional images, of the internal structures/organs of the body. CT exams are performed to analyze various parts of the body for abnormalities such as tumors or infections.
Community Medical Center currently has a total of three CT units offering state-of-the-art applications such as:
CT coronary angiography is a scanning method that produces outstanding images of the coronary blood vessels, as well as structure and function of the heart without the need for invasive catheterization. This technique uses an intravenous injection of contrast material, followed by thin section scanning through the area of interest. The computer generates a 3-D image of the delicate blood vessels.
A CT guided biopsy is a procedure performed by an interventional radiologist with staff from radiology nursing and the CT Department. Using the CT, the radiologist is guided to the precise area of interest for the biopsy. Patients receive a local anesthetic. The procedure can be performed on an outpatient basis and usually eliminates the need for a more invasive surgical biopsy. All the arrangements for a CT guided biopsy are made by the patient’s primary care physician.
Patients with certain allergies may have an adverse reaction to the intravenous contrast material. This may result in a rash, hives or a feeling of warmth throughout the body. Rarely, more serious allergic reactions may occur. All allergies should be discussed with your physician prior to scheduling a CT exam. Pre-medication may be necessary.
Patients with active asthma should discuss their condition with their physician prior to scheduling a CT exam. Pre-medication may be necessary.
Patients who receive intravenous contrast material before their CT scan will be given instructions by the radiology nurse not to take their glucophage for 48 hours after their CT exam.
In some individuals the contrast material may affect kidney function. The use of contrast material is determined by the patient’s attending physician in consultation with the radiologist.
For many CT exams, patients are asked not to eat or drink anything for several hours prior to their exam.
Instructions for preparation are given when the exam is scheduled.
When you arrive you will be asked to complete our Patient History Questionnaire. If you would like to review and complete the form prior to your arrival please click here (pdf).
Prior to the CT exam the technologist will explain the procedure. Depending on the type of exam your physician ordered, you might be given oral contrast material one hour before your scan. The radiology nurse may start an intravenous line needed to administer the contrast material.
The average CT exam takes between 15 and 30 minutes. The technologist will be in constant contact with you throughout the exam.
