We use a range of techniques to view what’s going on inside your body. Some of the most common imaging options we use include: CT: Using a combination of X-rays and a computer to create detailed images of the inside of your body, Dual-energy X-ray absorptiometry (DEXA): Using small doses of radiation to measure your bone mineral density (the quality and strength of your bones), Diagnostic ultrasounds: Also called sonography, using high-frequency sound waves to view the structures inside your body, Fluoroscopy: Using X-rays with a video screen to create a “movie” of the inside of your body, and Mammography: Using low-dose X-rays to examine breast tissue to detect and diagnose breast cancer.
