Radiology Imaging Systems and Services

Our state-of-the-art equipment improves and enhances:

  • Diagnostic accuracy and procedural outcomes
  • Efficiencies
  • Teaching and research
  • Your safety and comfort

Some of our primary imaging systems and services are described below:

Breast imaging

We conduct mammography screening and diagnostic studies on Hologic 3Dimensions™ Mammography System units.

We perform biopsies using the Hologic Affirm® Breast Biopsy Guidance System. This advanced system allows for a faster and more comfortable experience during your core breast biopsy. While you sit comfortably, we use the tomosynthesis guidance system.

We dedicate Philips Epiq 7 high-resolution ultrasound scanners for breast imaging. Our trained technologists and radiologists perform your breast imaging scan.

Breast-MR exams and interventions use:

  • 3 Tesla MR units
  • A Sentinelle™ Breast MR Auxiliary Table with 8-channel coil array
  • Philips DynaCAD breast MR image analysis system

Computed tomography

We provide computed tomography (CT) scans to make images of your body in a cross-sectional way. You can think of a CT image as a slice that allows the radiologist to look inside your body. CT shows healthy and diseased tissues inside the head, neck, chest, abdomen, pelvis, and extremities.

Our CT systems include:

  • One GE Lightspeed 16-slice scanner with fluoro for CT-guided procedures
  • A GE Lightspeed VCT 64-slice scanner
  • A Siemens Force scanner (a dual-energy, turbo flash scanner capable of sub-second imaging)

We also offer CT-guided interventions with the Siemens Somatom Definition™ AS system.

The Siemens system offers multiplanar fluoroscopic reconstruction and merged 3D/real-time imaging. We use this versatile 40-slice scanner for a range of image-guided percutaneous procedures.

DXA scanning

We provide a bone density scan or DXA (dual energy X-ray absorptionmetry) scanning service to measure your bone mass and how tightly it is packed. The service uses a Hologic Horizon A DXA system.

DX core

Our diagnostic X-ray (DX) and fluoroscopy core services are available in eleven exam rooms:

  • A PICC (placement of peripherally inserted central catheter) room
  • Two Fuji Devo GL panels
  • Three fluoroscopy rooms (using Philips ProxiDiagnostEleva™ systems)
  • Five rooms with automatic image-stitching capabilities

The DX Core utilizes:

  • Philips DigitalDiagnost™ systems as standard fixed equipment
  • Five Philips Digital Portables
  • Two Carestream Digital Portables deployed as needed throughout the medical center

The DX Core team also handles imaging services in the Emergency Department, where it operates a:

  • DigitalDiagnost VM unit
  • TraumaDiagnost™ CS-4 (easily repositioned from a mounted overhead rail system for use at any of the three Emergency Department bays)

Interventional radiology/angiography

We provide diagnostic imaging and interventional therapeutic services to both inpatients and outpatients.

Our imaging systems include:

  • Five fluoroscopic procedure rooms
  • An ultrasound-guided procedure room

The fluoroscopic rooms consist of:

  • A GE Innova 4100 single plane
  • A Siemens Axiom Artis Zee biplane
  • A Siemens Axiom Artis Zee single plane
  • A single plane Philips Azurion
  • An OEC c-arm

Magnetic resonance imaging

Magnetic resonance imaging (MRI) is a technique that allows us to view cross-sectional pictures of your body. Your doctor may order this test to view images and to verify a specific disease. MRIs use a magnetic field and radio waves to generate images and presents no risk to patients.

Our department utilizes 5 clinical MRI systems:

  • The GE MR750 3T magnet
  • A new upgraded GE Explorer 1.5T system
  • A large-bore Siemens Aera 1.5T system
  • Two large-bore Siemens Skyra 3T magnets

We also maintain systems for research purposes:

  • A Siemens Prizma 3T system at Dartmouth Hitchcock Medical Center's Advanced Imaging Center
  • Several small-animal research magnets at the Vail and Rubin research laboratories

Nuclear imaging

Nuclear medicine is a type of medical imaging that uses radioactive materials to diagnose or treat various diseases, such as:

  • Heart disease
  • Many types of cancers
  • Other abnormalities within the body

Our Nuclear Imaging division utilizes five scanning systems:

  • BiodexAtomlab 960 Thyroid uptake probe and well count
  • GE Infinia Hawkeye SPECT/CT
  • Siemens Biograph Vision PET-CT
  • Siemens Symbia T6™ SPECT-CT unit
  • Siemens SymbiaIntevo Excel SPECT-CT

PET scanning

A positron emission tomography (PET) scan can detect abnormal metabolism of cells and assist with diagnosing cancer, cardiac disease, and neurologic disorders.

The PET scan:

  • Uses molecular scanning techniques to measure glucose metabolism in cells
  • Can determine the exact size, shape, and location of diseased tissues

Ultrasound is the use of sound waves to make pictures of organs and tissues in the body. It is painless and safe. Sound waves do not damage tissue, even when used to examine a baby before it is born.

An ultrasound can help your doctor make a quick and accurate diagnosis by:

  • Detecting damaged tissue
  • Identifying a wide variety of conditions
  • Locating abnormal growths

Our Ultrasound imaging section operates six exam rooms at the Ultrasound/Mammography (3S) location and two in the OB/GYN (5M) clinic. We offer the most state-of-the-art imaging available on Philips EPIQ & GE Voluson systems.
