Computed Tomography (CT or CT Scan)
Lawrence General is equipped with two CT scanners, one located in the Radiology Department and the other in the Emergency Center.
A CT scan combines special x-ray equipment with sophisticated computers to produce multiple cross-sectional images of a specific area of the body. The test involves you lying on a table which moves in and out of a large, donut shaped circle. The final images are viewed and read by the radiologist.
While radiation dose from CT scans has been in the news lately, Lawrence General Hospital has always selected equipment that protects our patients and staff from unnecessary radiation. We utilize the ALARA principles (As Low As Reasonably Achievable) and the Siemens CareDose program to reduce radiation exposure.
Our staff is "kid friendly" and the CT protocols have been "child sized" to keep exposure to a minimum.
Types of CT Exams
- CT Angiography (images of blood vessels)
Preparation for CT Exams
Certain tests require you to drink an oral contrast agent, which will highlight the digestive tract on the CT exam. In addition, an intravenous injection of contrast may also be needed to highlight other organs, arteries and veins. Your doctor and the radiologist will determine which contrast you will need based on your symptoms and medical history.
Not all CT exams require preparation. If you are scheduled for an exam that requires an oral prep you will be asked to arrive 2 to 3 hours prior to your appointment time. The CT technologist will review your medical history and give you further instructions. It is important that you bring a written list of all medications you are taking.
Your physician will give you specific instructions regarding arrival time, scan time and whether or not you need to fast for the procedure. If you have any questions do not hesitate to call our CT Team at 978-946-8103.
CT scans are covered by most insurance companies but do require a physician's order and in most cases preauthorization from your insurer. If you have any questions regarding your co-pay and/or deductible you should consult your insurance carrier.
