Diagnostic Imaging Center

Mid Ohio Oncology/Hematology Inc. offers diagnostic radiology services. Computed tomography (CT) combines the latest computer technology with the use of general X-rays. Using a thin beam of radiation, the CT scanner creates a cross-sectional image of the area being imaged and is repeated throughout the specified body region. The computer then reconstructs the “slice” to create the actual image being viewed.

Frequently Asked Questions:

Why do I need a CT scan?
With greater imaging detail than conventional X-rays, your doctor may recommend this type of diagnostic procedure when there is a need to evaluate soft tissue or organ function. Being imaged in cross-sectional format, your doctor has a better advantage to the size, shape and location of the structures being scanned.

What should I expect during the scan?

• For most individuals, scanning takes only a few seconds. However, depending on the exam and placement of the IV, the total times will vary.
• Depending on the exam, you may be asked to change into a gown to prevent your clothing from obstructing the X-ray beam.
• Once you are positioned on the couch or “table” you will then be placed into a doughnut-shaped gantry. This unit houses everything it needs to create the invisible X-ray beams.
• Very little noise is created by the CT’s gantry. There is a mild humming generated by the mechanical rotation of the gantry.
• During the scan, you may receive an IV contrast agent along with drinking an oral barium contrast prior to the exam.
• While scanning, you will be required to lie very still. The technologist may instruct you to hold your breath for a short time.

Does the exam require contrast media?
95 percent of the CT scans performed at Mid Ohio Oncology/Hematology, Inc. will require you to have two types of contrast media (X-ray dye).

• Barium contrast is taken orally prior to the exam to allow better definition of the bowel structure.
• Ultavist 300, an IV contrast is administered during the exam. This may cause a slight warming sensation throughout the body and may leave a metallic taste in your mouth just for the length of the injection.

WARNING
Although IV contrast is not harmful, it is commonly iodine-based, which can trigger an allergic reaction in some patients.

Those persons allergic to iodine should notify their doctor prior to any CT exam.
