CT Scans

A CT scan (Computerized Axial Tomography) is a diagnostic test that combines the use of X-rays with computer technology.  A series of X-ray beams from many different angles are used to create cross-sectional images of the patientís body.  These images are assembled in a computer into a three-dimensional picture that can display organs, bones and tissues in great detail.  Because of the acquisition of an extremely large number of thin slices quickly obtained, this multi-slice detector system allows for multi planar and 3D reconstruction images on our computer workstations.  This greatly aids the diagnosis of tumors, kidney stones, appendicitis, and coronary artery as well as other vascular calcifications.


CT scan of your abdomen and/or pelvis allows precise visualization of the organs and structures within your abdominal and/or pelvic cavity. A series of images will be obtained at various angles allowing for detailed examination of the abdominal organs.

*Oral Contrast: You will be asked to pick up a container of oral contrast from the Radiology Department. You will need to drink this contrast before coming to the office for your CT scan. Therefore, it is important that you pick up the oral contrast no later than the day before your scan. During the CT scan, you may also be given contrast media intravenously.


A Chest CT scan takes many pictures, called slices, of the lungs and the inside of the chest. A computer processes these pictures; they can be viewed on a screen or printed on film. The computer also can stack the pictures to create a very detailed, three-dimensional (3D) model of organs.  Sometimes, a substance called contrast dye is injected into a vein in your arm for the CT scan. This contrast highlights areas in your chest, which helps create clearer images.

Head & Neck

CT of the Head is fast and readily available, which makes it a great choice for trauma evaluation, sudden onset of headaches, and sinus disease. CT is also alternative to MRI when patients cannot have an MRI exam due to pacemakers, aneurysm clips, pain stimulators and metal implants. 

CT of the neck is the preferred exam when evaluating the soft tissue structures of the neck. The scan includes the orbits through the top of the lungs and is used extensively to evaluate the glands and lymph nodes of the neck.

IV contrast media is often indicated for an accurate evaluation of the vasculature and/or disease. The need for IV contrast is determined by the physicians requesting or performing the scan.


A CT IVP is an x-ray examination of the urinary system. The urinary system consists of the kidneys, bladder, ureters (tubes that carry urine from kidneys to bladder) and urethra (tube through which urine passes from the bladder to the outside of the body). A CT IVP requires the use of a contrast material (dye) to enhance the x-ray images. This material contains iodine, so it is important that your healthcare provider be aware of any allergies you may have. The contrast material is injected into your venous system through a vein and as it progresses through the urinary tract, pictures are taken. This allows the radiologist to review the anatomy and function of the kidneys and urinary tract. A small amount of radiation is used with a CT IVP to capture the images, but the benefits of the procedure far outweigh any risks of radiation exposure.
