Optimal Imaging: Mandarin

CT scans use an X-ray generating device that rotates around your body and a powerful computer to create cross-sectional images. When you arrive for your test, you will change into a gown and lie on a table that slides in and out of a large tube called a CT. It is a painless imaging test that takes only minutes to complete.

DEXA scans are most commonly used to diagnose bone thinning, such as osteoporosis. Loss of bone density may be caused by rheumatoid arthritis, eating disorders, aging and having cancer treatment. They may also be used to measure your overall body composition, including fat and lean tissue. Before the scan, you will be asked to wear comfortable, loose fitting clothes or change into a gown. During the scan, you will lay flat and still on a table. The scan typically lasts about 15-20 minutes.

A digital mammogram is a low-dose X-ray system that takes electronic pictures of the breasts to screen for disease and diagnose cysts and breast cancer.

On the day of your mammogram, do not use deodorant, powder or lotions. We also recommended wearing a top that is easy to remove, since you will be asked to undress from the waist up and wear a gown. During the procedure, the technologist will position your breast to get the clearest test results. Then, each of your breasts will be compressed one at a time. This helps get a high-quality X-ray image. Your breasts will be repositioned to get at least two separate views of each breast. The entire procedure is about 20 minutes, but the actual breast compression is only a few seconds.

An MRI uses strong magnetic fields to create detailed images of organs and other structures in your body. During your appointment, you will be asked to change into a gown and remove all jewelry, glasses, and hearing aids. You will lie flat in a tube that is open on both ends. The tube then slides into the MRI machine. For some MRI tests, a contrast dye is inserted through an IV. The scan may last anywhere from a few minutes to over an hour, depending on what images are needed.

Ultrasound uses sound waves to produce sonogram pictures or videos of structures inside of your body. There are several different types of ultrasounds. Your care team will explain how to prepare for your ultrasound and what to expect during it.
