Welcome to Stanford Health Care – ValleyCare's Department of Radiology. Our highly skilled, caring staff and board-certified radiologists are dedicated to providing the highest-quality patient care. Our state-of-the-art facilities offer a broad range of imaging services in comfortable surroundings close to your home or workplace.

Diagnostic Imaging

Stanford Health Care – ValleyCare Department of Radiology offers state-of-the-art imaging services including CT, MRI and PET/CT.

Computed Tomography (CT)

CT scans are imaging tests that may be done to help diagnose tumors, investigate internal bleeding or check for other injuries or damage. If you need a CT scan, you can rest assured that Stanford Health Care – ValleyCare offers the latest advances in CT technology, including computed tomographic angiography (CTA), which is used to obtain images of blood vessels.

CT Lung Cancer Screening

Lung cancer is the most lethal cancer in America today, and the best treatment for lung cancer, as with all cancers, is early detection. The medical community is recommending through published studies that there is a significant benefit to lung cancer screening using low-dose CT. Therefore, our Imaging Department will be offering this screening test to patients who meet the criteria recommended in either the U.S. Preventive Services Task Force (USPSTF) or National Comprehensive Cancer Network (NCCN) guidelines. View an overview of this screening program, including what to expect and eligibility.

Magnetic Resonance Imaging (MRI)

MRI is an imaging test that allows physicians to look at the inside of the body using magnetic fields without the use of X-rays. The test may be done to check for medical problems such as tumors, heart or blood vessel trouble, uterine fibroids or problems affecting the abdominal organs (such as the liver), small intestine, colon, rectum or urinary tract.

PET/CT Imaging

PET/CT imaging merges the technologies of PET (positron emission tomography) and CT (computed tomography) into a single machine. PET is a test that uses special imaging cameras and a radioactive type of sugar to produce pictures of the function and metabolism of cells in the body. CT uses x-rays to generate a detailed view of the anatomy or structure of organs and tissues in the body. A CT scan can show the dimension of vessels, lymph nodes and organ systems. Combined, they are able to produce scans that provide a merged picture of both the body's metabolism and structure.

Bone Densitometry

This diagnostic test is used to check the amount of mineral in bones and to help identify a person's risk of fracture before a fracture occurs. In this 15–20-minute test, a low-dose x-ray beam scans the spine, hip or both. The scan measures the density of your bones and gives you a good picture of your bone health. Your doctor can then recommend a specific course of action if needed. There is no known risk from DXA other than minimal radiation exposure.
