Tanner's Diagnostic Imaging Department offers a spectrum of services including radiology (X-ray), ultrasound, nuclear medicine, fluoroscopic studies, full gastrointestinal imaging, CT scan and MRI imaging. Additional specialized imaging capabilities include cardiac imaging, coronary artery calcification screening, non-invasive imaging of arteries and veins and Women's Center imaging studies (mammography, bone density, and ultrasound).
Test Preparation
Outpatient imaging often requires some form of preparation. Physicians should provide instructions on what may be needed for a particular test. Patients with questions should call:

Bone Density Study (DEXA scan)
A bone density study is a low dose X-ray that is used to screen for osteoporosis.
CT or Computed Axial Tomography
A CT (also known as CAT scan or Computed Axial Tomography) scan is a special X-ray which shows detailed cross-sectional anatomy including major organs, soft tissue and bone. The scan can detect specific infections, cancers, embolism, aneurysms, blockages, abnormal growths, tumors, enlargements, injuries or deformities.
Gastrointestinal Imaging
An Upper GI is an X-ray exam to examine the stomach. Patients drink a contrast material called barium while the radiologist takes images using fluoroscopy. The procedure takes about 20 – 30 minutes.
A Barium Enema is an X-ray exam of the colon. Contrast material is given through an enema and the radiologist uses fluoroscopy as the colon fills. The procedure time is about 30 – 45 minutes.
Magnetic Resonance Imaging (MRI)
MRI is a highly advanced testing procedure that allows physicians to visualize inside the body without the use of surgery or exposure to X-ray radiation. Using a strong magnetic field combined with radio waves, a computer generates images of soft tissues and organs within the body.
Mammogram
A Mammogram is a low-dose X-ray of the breast that is used to identify anatomy. It is recommended that women receive a baseline mammogram at age 35 and annually after age 40.
Nuclear Medicine
Nuclear medicine involves the use of radioisotopes and special imaging equipment to diagnose a variety of diseases and disorders. Patients are given a radiopharmaceutical that is injected, inhaled or swallowed. This compound travels to the part of the body of interest and is detected by the imaging equipment.
Nuclear medicine images can assist a physician in diagnosing diseases and assessing gland function.
Ultrasound
Ultrasound is a method of testing that uses sound waves to obtain real-time pictures of the body’s internal organs. Ultrasound is a way of looking inside the body without the risks associated with surgery or radiation.
X-Ray and Fluoroscopy
X-rays and fluoroscopy use small doses of radiation to take internal images of the body. X-rays are still pictures, while fluoroscopy procedures produce live pictures on a computer screen.
