Red Rock Radiology

Red Rock Radiology is the only facility in Nevada currently offering 3D Computer Aided Detection (CAD) mammograms. Studies have shown that using CAD can help detect breast cancer earlier, when it can be more easily treated.

Red Rock Radiology and MountainView Hospital have taken the pledge to reduce the imaging radiation dose for adults and children.

Red Rock Radiology at MountainView offers MRI, CT, nuclear medicine and X-ray services for our patients. We will be adding a bi-plane machine to treat stroke by the end of 2017.

Red Rock Radiology at MountainView offers a 64 and 256-slice CT, as well as a dedicated CT in the Emergency Department.

The advanced technology of the 256-slice CT system combines speed and high-quality images to provide you a better CT experience.

MountainView’s 256-slice CT can scan entire organs in less than one second, so you don’t have to hold your breath as long. Additionally, it reduces your radiation dose up to 82% no matter what kind of scan you are having. This also allows pediatric patients with low-dose, sedation-free exams.
