Computed Tomography (CT Scan)

State-of-the-art computed tomography (CT) services are available at both the LMH Health Main Campus and the West Campus. CT technology allows radiologists to produce high-quality images, reduce patient exposure to X-rays and provide accurate diagnoses.

CT scans are generally used to determine the condition of organs and bone structures. Targeted CT scans help diagnose various cancers, including lung, liver and pancreatic cancer, as well as heart disease.

CT Scans and Services

A CT scanner uses a minimal amount of radiation, and it processes information digitally to allow radiologists to see very clearly inside the patient's body. The following CT scans are available at LMH Health:

• Chest CT
• Head and Orbits CT
• Myelogram/Spines with contrast
• Sinuses-Facial Bones CT
• Soft Tissue Neck CT
• Abdomen and pelvis CT, including liver, spleen, gallbladder, kidneys, aorta and pelvic organs
• CT Angiograms
• Aspirations/drainages

What to Expect During a CT Scan

CT scanning causes no pain, and spiral CT technology reduces the need to lie still for a particular length of time. Preparation varies according to the body part being scanned. You may be asked to swallow a positive contrast material, a liquid that allows the radiologist to better see the stomach, small bowel and colon. (Some patients find the taste of the contrast material mildly unpleasant, but most can tolerate it with ease. After taking the contrast, you may briefly experience a sense of abdominal fullness that goes away quickly.)

For some patients, a contrast material is injected into a vein to better define the blood vessels and kidneys, and to accentuate the appearance between normal and abnormal tissue in organs like the liver and spleen. Some people report feeling a flush of heat and sometimes a metallic taste in the back of the mouth. These sensations usually disappear within a minute or two.

During the scan, you will be alone in the room, yet the CT technologist can see, hear and speak with you at all times. For pediatric patients, a parent may be allowed in the room to alleviate fear. For safety purposes, the parent is required to wear a lead apron to prevent radiation exposure.
