We were the first hospital in Nashua to earn accreditation for CT scanning by the American College of Radiology for excellence in CT imaging and patient care. A CT scan uses specialized, rotating x-ray equipment and a digital computer to produce detailed cross-sectional and/or three-dimensional images of body tissues, bones, and organs. This type of scan is very helpful in diagnosing diseases that conventional x-rays may not see.

In the diagnosis and treatment of heart disease, cancer, stroke, lung disease and other serious conditions, the remarkably detailed images from our GE VCT-64 slice scanner provide high resolution, 3-D images in lightning-fast speed and allow your doctor to make more informed decisions about your care. In emergency traumas, quick CT results allow doctors to start life-saving measures sooner.

CT angiography also allows for imaging of the heart and blood vessels and provides the first non-invasive means to see detailed views of coronary arteries.


Speak with your doctor if you have had multiple CT scans in the past five years. CT scans involve exposure to radiation, which is cumulative in the human body. The benefit of receiving an accurate diagnosis generally outweighs the risks associated with radiation exposure. Our Radiation Protection Program serves to minimize this risk.

If you are diabetic, have asthma, a history of kidney problems, have been diagnosed with heart failure, or if you have had a past allergic reaction to contrast material, tell your doctor. There is a small risk of allergic reaction to the IV contrast material (x-ray dye) that contains iodine. If there is a chance that you may be pregnant, notify your doctor and/or x-ray technologist.

The Procedure

Most CT exams take 20 minutes or less. A technologist will position you on a table that moves slowly through a large, donut-shaped machine. You may be asked to hold still or to hold your breath at certain times. An injection of IV contrast may be required to highlight certain organs and blood vessels. You may temporarily feel a warm sensation from this injection. When the exam is over, you may be asked to wait until the images are reviewed to determine if more images are needed.
