Low Dose CT Available for Safer Scans
Bayhealth offers the world's first high-definition, low-dose Computed Tomography (CT) system with ASiR™ - the CT750 high definition (HD) system from GE Healthcare. This advanced technology reduces radiation exposure up to 50% compared to other existing CT technology.
With more 64-slice CT units than any other health system in our area, Bayhealth Diagnostic Imaging Services provide more effective diagnostics to move to treatment more efficiently.
Accredited by ACR for Expertise in CT Imaging
Computed Tomography (CT) diagnostic imaging at Bayhealth is accredited by the American College of Radiology, a national accrediting organization that mandates diagnostic quality and safety standards. CT accreditation at Bayhealth is a result of excellence in imaging, dose measurements and scanning protocols.
What is a CT scan?
With computed tomography, our specially trained diagnostic physicians can determine greater detail about internal organs and other structures than with traditional X-rays. With computed tomography scans (also called CT or CAT scan), the X-ray beam moves in a circle around the body to allow for many different views for a more informed and advanced diagnosis.
CT scans may be done with or without contrast. Contrast refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue being studied to be seen more clearly.
Before a CT Scan
If your procedure involves the use of contrast dye, you will be asked to sign a permission or consent form. Please read the form carefully and ask questions if something is not clear.
Generally, there is no fasting requirement prior to a CT scan, unless a contrast dye is to be used. Your doctor will give you special instructions ahead of time if contrast is to be used and if you will need to withhold food and drink.
Notify the technologist:
- If you have ever had a reaction to any contrast dye, or if you are allergic to iodine
- If you are pregnant or suspect you may be pregnant
- If you have any body piercing on your chest and/or abdomen
What to Expect During a CT Scan
CT scans may be performed on an outpatient basis or as part of your stay in a hospital. Generally, a CT scan of the bones, joints, and soft tissue follows this process:
- You will be given a gown and asked to remove any clothing, jewelry, or other objects that may interfere with the procedure.
- If you are scheduled to have a procedure done with contrast, either an oral medication will be given to swallow, or an intravenous (IV) line will be started in the hand or arm for injection of the contrast dye. You may feel some effects when the dye is injected into the IV line, including a flushing sensation, a salty or metallic taste in the mouth, a brief headache, or nausea. These effects usually last for just a few moments.
- You will lie on a scan table that slides into a large, circular opening of the scanning machine.
- The technologist will be in another room where the scanner controls are located. However, you will be in constant sight of the technologist through a window and speakers inside the scanner will enable the technologist to communicate with and hear you. You will have a call button so that you can let the technologist know if
- you have any problems during the procedure.
- The scanner will begin to rotate around you and scans will be recorded. You will hear clicking sounds, which are normal.
- It will be important for you to remain very still during the procedure. You may be asked to hold your breath at various times during the procedure.
- You should notify the technologist if you feel any breathing difficulties or any other unusual symptoms such as sweating, numbness, or heart palpitations.
- If an IV line was inserted for contrast administration, the line will be removed.
After a CT Scan
If contrast dye was used during your procedure, you may be monitored for a period of time for any side effects or reactions to the contrast dye, such as itching, swelling, rash, or difficulty breathing. If you notice any pain, redness, and/or swelling at the IV site after you return home following your procedure, you should notify your doctor as this could indicate a reaction.
