MRIs, X-rays and Other Tests

At Sierra Vista Regional Medical Center, we offer a wide range of diagnostic imaging tests and screenings to diagnose, treat and prevent illness and injuries. Here’s a look at some of our imaging services and examples of how they’re used. Call (805) 546-7676 to make an appointment.

Bone Densitometry

Uses low-energy X-rays to scan the lower back, hip or forearm. This helps to diagnose osteoporosis, a disease that weakens bones and makes them more brittle and susceptible to fracture.

CT Scan

Combines X-rays and computer scans to create images of the body. The result is a detailed image that can show problems with soft tissues, organs and bones. This unit has the ability to produce CTA studies (angiography) of the aorta and pulmonary arteries, and the multi-detector accelerates patient throughput. Additionally, this CT system has an independent workstation for 3-D multi-format imaging.

Digital Mammography

Uses X-rays to visualize abnormalities in the breast tissue. This equipment is used to detect breast cancer as early as possible, which generally improves the effectiveness of treatment.

3D Mammography

3D mammography uses multiple low-dose images to create a 3-dimensional view of the breast.  This procedure allows the doctor to examine the 3D breast layer by layer.  Fine details are more clearly visible because they are no longer hidden by the tissue above and below.


Provides detailed pictures of the inside of the body using strong magnets and radio waves. This unit is notable for its ability to provide greater spatial resolution of images.

Stereotactic Breast Biopsy

A breast cancer imaging option that produces stereo images—images of the same area from different angles. This helps to determine the exact location for the biopsy where a sample of breast tissue is then removed with a needle.


Our ultrasound technology uses sound waves to produced 3D/4D images of the body's interior. (Expectant parents will delight in seeing detailed pictures of their baby in utero produced by this system.)


Uses a small amount of radiation to create images of bones and organs.
