Imaging Services

Medical Imaging is one of the most important tools the doctor has for diagnosing and treating your medical condition. Queen of the Valley Medical Center Imaging Services provides the highest standards of imaging for every patient. We support the Mission and Vision of Queen of the Valley Medical Center and apply our Core Values of Dignity, Service, Excellence and Justice by identifying and meeting each patient’s physiological, spiritual, and sociological needs.

QVMC Awarded Three-Year Accreditation in Mammography by the American College of Radiology

Remarkable advances in imaging technology have been made in just the past few years. Napa Valley Imaging Center, our outpatient imaging facility (view virtual tour), offers the latest and most effective imaging options available. Our high field MRI scanner produces more precise images than ever before. The larger opening of our scanner also increases comfort and reduces discomfort for our patients. This technology makes it possible for us to create remarkably clear three-dimensional cardiovascular, vascular, and musculoskeletal images. We now have the ability to see, evaluate, and recommend preventative treatments more quickly and accurately than ever before.

Our new PET/CT scanner incorporates PET (Positron Emission Tomography) and CT (Computed Tomography), combining two state-of-the-art technologies to help physicians more accurately diagnose and identify cancer and other disease processes.

To schedule a MRI, CT or PET/CT scan contact the Napa Valley Imaging Center Scheduling Department at (707) 251-1700.

Images created by our leading edge equipment are stored in our digital Picture Archive and Communication System (PACS). Because PACS stores scanned results as secured digital images instead of on film, it allows your physician to access those images and reports on-line, 24 hours a day. Imaging Services offered by Queen of the Valley Medical Center include Diagnostic Radiology, Interventional Radiology, Nuclear Medicine, CT, Ultrasound, and Echocardiography.

To schedule an appointment in one of these areas please contact Central Scheduling at (707) 257-4036.


Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) uses a strong magnetic field and radio waves to image the body. MRI is commonly used to examine the brain, spine, joints, abdomen and pelvis. A special kind of MRI exam, called magnetic resonance angiography (MRA), examines blood vessels throughout the body.

MRI is an incredibly accurate diagnostic tool that quickly and non-invasively provides accurate diagnostic images for your physician. In some situations MRI can reduce the need for exploratory surgery or other diagnostic procedures that often have greater risks.

PET / CT (Positron Emission Tomography and Computed Tomography)

A Positron emission tomography (PET) scan combines the advantages of computed tomography (CT) and nuclear scanning. During a PET scan, a radioactive substance called a tracer is combined with an inert chemical (such as glucose). This “traceable” solution is then injected into a patient’s vein in the arm or hand. The PET/CT scanner simultaneously applies two powerful imaging technologies - the functional images of PET and the anatomical images of CT - to allow physicians to "see" clear pictures of not only complex body structures but also dynamic metabolic processes as they are occurring. Hailed as one of the most significant advances in modern cancer treatment, PET/CT helps doctors detect and treat very small malignancies.

Tomography (CT)
CT scans were developed originally to diagnose brain disorders. They are now used to collect images of tissues throughout the entire body. The clarity and detail provided by a scan often make it unnecessary for patients to undergo exploratory surgery. Modern CT scanners create only an ultra-thin, low dose X-ray beam, so radiation exposure is minimized. CT scans provide greater detail than standard x-rays and can provide a more detailed visualization of the internal organs and soft tissues. We have a Siemens Dual Source scanner located in the medical center’s imaging department on the lower level. We also offer a state-of-the-art PET/CT scanner at the Napa Valley Imaging Center.

Diagnostic Radiology

The Diagnostic Radiology Department performs standard radiographic and fluoroscopic imaging studies including procedures such as x-rays to detect broken bones, evaluate lung function and gastrointestinal disease processes. Diagnostic Radiology also performs exams during surgical procedures.

Interventional Radiology

The hospital’s Vascular Interventional Lab (VIL) provides diagnostic and treatment options such as angiograms for diseases of the vascular system and visceral organs. They use fluoroscopy (X-rays) to perform minimally invasive procedures in treating such problems as clogged arteries in areas of the body other than the heart such as the arms, legs and kidneys. The latest addition to our Vascular Interventional Lab capabilities is the use of lasers to directly remove the plaques and blood clots that threaten blood flow to the legs and feet. This exciting, new device can reduce the need for amputation in patients with severe peripheral vascular disease and improve the quality of life for those with less severe disease.

Diagnostic Ultrasound and Echocardiography

Ultrasound or Sonography uses sound waves to detect abnormalities in many parts the body. Internal organs and structures reflect the sound waves. Special instruments create an image of the desired area then interpret the reflections. Echocardiographic testing uses sound waves to create an image of the heart. This non-invasive test is particularly useful in detecting and managing heart disease and is one of the standard tools applied by cardiologists.

Nuclear Medicine

Nuclear medicine uses a camera (detector) to create an image of certain tissues and organs in the body after a radioactive tracer (radionuclide or radioisotope) accumulates in the tissues. The radioactive tracer, usually injected into a vein, allows images to show how organs and tissues are functioning. Our Imaging Department has two nuclear medicine camera systems, both with two detectors for faster imaging. Nuclear Medicine exams include bone scans, thyroid uptake and scans, myocardial perfusion imaging (Cardiolite Stress Tests), hepatobiliary imaging, white blood cell imaging, parathyroid imaging, and kidney imaging.
