Imaging & Radiology

Innovative Diagnostic and Therapeutic Procedures at MarinHealth

Radiology is an area of medicine that focuses primarily on the use of imaging technologies to diagnose disease. As technology has advanced and become more accessible, radiology and imaging are now at the center of patient care, providing the ability to diagnose, monitor, and even treat disease.

Our new central location allows radiologists to collaborate much more efficiently with the emergency, surgery, and intensive care departments.

ED patients in need of a CT, MRI, or ultrasound have immediate access due to strategic placement of the imaging department next to our emergency department.

Our team is dedicated to providing our patients with best-in-class technologies, using the most advanced X-ray, CT, MRI, molecular imaging, and ultrasound equipment, all coupled with state-of-the-art computer technology.

Request an Appointment

Need to schedule an appointment for an imaging service? You can request an appointment that works best with your schedule, utilizing our online system. A MarinHealth Representative will respond to your inquiry and confirm an appointment time with you. Please note: Patients requiring x-ray screenings do not need to schedule an appointment. X-Ray screenings are available on a first-come, first-serve basis at all of our locations.

Our Services Include:

Bone Density Testing
Bone density testing is used to diagnose and monitor osteopenia and osteoporosis (bone loss). Testing is provided using dual-energy X-ray absorptiometry, an advanced bone density test known as DEXA.

CT Scans
Computer-assisted tomography (CT) combines multiple X-ray images of the body from different angles to create a cross-section, 3D view of the scanned area. Our experts have access to two latest-generation 256-slice and 64-slice scanners.

Fluoroscopy can be described as an X-ray “movie.” This imaging technique allows the radiologist to view X-rays of a body part moving in real time.

Interventional Radiology
A medical specialty that uses sophisticated image guidance to deliver minimally invasive, precisely targeted treatments. Interventional radiology is increasingly replacing conventional surgical techniques for a wide range of conditions.

In keeping with our commitment to the early diagnosis of breast cancer, our Breast Health Center utilizes 3D digital mammography, along with computer-assisted diagnosis for ALL mammograms. Our Breast Health Center runs a high-risk breast program and provides procedural services involved in the diagnosis and management of breast cancer.

Molecular Imaging / Nuclear Medicine
Whereas other types of diagnostic imaging procedures offer detailed pictures of physical structures in the body, molecular imaging uses targeted radiopharmaceuticals to illustrate what is happening inside the body at the cellular and molecular level. PET imaging is included within this subspecialty of imaging.

Magnetic resonance imaging (MRI) produces images using a strong magnetic field and radio waves. MarinHealth is the only medical network in our region to utilize a 3 Tesla (3T) MRI system, a high field strength digital broadband MRI scanner that delivers exceptionally accurate and detailed images.

Ultrasound examinations use high-frequency sound waves that are transmitted through skin tissues to create an image.

X-ray Imaging
Small, controlled doses of ionizing radiation are used to image parts inside the body. X-ray technology has evolved considerably over the decades. We provide the highest fidelity direct digital X-ray units at our main campus and our Outpatient Imaging Centers in Greenbrae and San Rafael. This advanced technology reduces X-ray exposure to our patients.
