Upgrading and expanding imaging systems are an ongoing priority and are essential to all areas of our mission: state-of-the-art equipment improves diagnostic accuracy and procedural outcomes, improves efficiencies, improves patient safety and comfort, and enhances teaching and research.
The diagnostic X-ray and fluoroscopy core, a designated Philips Healthcare "luminary site," consists of eleven exam rooms—among which are three fluoroscopy rooms, a PICC room, and two rooms with automatic image-stitching capabilities. Apart from the fluoroscopy rooms—which use Philips EasyDiagnost Eleva™ systems— the Core utilizes Philips DigitalDiagnost™ systems as standard fixed equipment; eleven older GE portable CR units are deployed as needed throughout the medical center.
The DX Core team also is responsible for imaging service in the Emergency Department, where it operates a DigitalDiagnost VM unit (which includes Philips' new wireless portable detector), and the TraumaDiagnost™ CS- 4. The CS-4 unit is mounted on an overhead-rail system designed by former Facilities Manager Paul Roy, an innovation permitting the scanner to be easily repositioned for use at any of three ED bays.
The department operates a bone densitometry scanning service, utilizing the Hologic Delphi-W DXA system.
The department utilizes six clinical MRI systems: the GE MR750 3T magnet (installed March 2010), a new GE HDX 1.5T system, an upgraded GE Signa Twin Speed 1.5T, two leased 1.5T systems on mobile platforms, and the ONI Medical Systems' MSK ExtremeTM 1.5T scanner—installed here in early 2009 as the first clinical application anywhere of this innovative system for imaging hands, arms, legs and feet. In addition, the department maintains a Philips 3T system used primarily for research purposes and housed at DHMC's Advanced Imaging Center, and several small-animal research magnets at the Vail and Rubin research laboratories.
The Ultrasound Imaging Division operates six exam rooms, and equipment consisting of five Philips HDI scanners, two Philips iU22 systems, and four Siemens Antares™ units.
The four-room angiography suite for VIR procedures includes two GE single-plane angiography systems, a GE Advantx™ LCN biplane unit, and a new (Jan. 2009) Siemens Axiom Artis zee™ biplane system that facilitates a range of interventional neuroradiology procedures.
The Nuclear Imaging Division utilizes four scanning systems: the Siemens Symbia T6™ SPECT-CT unit (Feb. 2009); the GE Infinia Hawkeye SPECT/CT; the GE Discovery ST™ PET-CT; and a Marconi IRIX Gamma Camera.
CT systems include: two GE Lightspeed 16-slice scanners, and a GE Lightspeed VCT 64- slice system. In early 2009 we expanded our capacities in CT-guided interventions with the Siemens Somatom Definition™ AS system; offering multiplanar fluoroscopic reconstruction and merged 3D/real-time imaging. This versatile 40- slice scanner is used for a range of image-guided percutaneous interventions.
Mammography screening and diagnostic studies are conducted on five Hologic Selenia™ full-field digital mammography systems. Biopsies are performed using a Selenia MultiCare™ Platinum stereotactic biopsy system. Breast-MR exams and interventions utilize a Sentinelle™ Breast MR Auxiliary Table with 8-channel coil array. A new (2009) Hologic™ tomosynthesis system is used for clinical studies.
