Dilon Molecular Imaging System

mis-banner

The Dilon Molecular Imaging System is a general-use molecular imaging camera that is designed to image various organs, but has been optimized to perform Molecular Breast Imaging (MBI), providing a vital diagnostic adjunct to mammography and ultrasound. The Dilon MBI procedure is an excellent problem-solving tool when faced with a difficult-to-diagnose patient, especially those with dense breasts. More information on general nuclear medicine imaging capabilities with the Dilon system.

Compact Digital Detectordilon-(2)

  • Available in two sizes;
    • The standard Dilon 6800®: 6” x 8” (15 x 20 cm), and
    • The Dilon 6800 Acella®: 8” x 10” (20 x 25 cm)
  • Allows imaging close to the chest wall, thus minimizing dead space.
  • Portable gantry eliminating the need for installation or a dedicated exam room and allowing use at several points of care.
  • Movable detector head allows imaging in all mammographic positions, plus selective study of hard-to-reach areas such as the axilla.
  • May be located in or near the breast center for same-day diagnostic imaging.

Digital Detector Technology

  • Lightning-Bright multi-crystal, wave-shifting array
  • Light Guide – proprietary light concentrating optics
  • Dilon Maxis high-density, high-resolution detector data point sampling system
  • Smart-Logic – patented digital signal processing algorithm CLEARSHIELD

Proprietary Breast Positioning – Clear Shield

  • Proprietary breast imaging paddle allows “see through” for easy positioning.
  • The breast shield insert decreases scatter radiation from nearby organs improving image quality
  • Stabilizes the breast without painful compression

Collimator options

  • Low Energy General Purpose (LEGP) Collimator: Optimized to perform Molecular Breast Imaging including lymphatic imaging  (lymphoscintigraphy).
  • Slant 15 Collimator: This 15-degree slanted collimator minimizes dead space along the edge of the detector, improving visualization of lesions near the chest wall.
  • Low Energy High-Resolution (LEHR) Collimator: Enhances thyroid imaging without the need of the pinhole collimator. Can also be used for other general molecular imaging applications.

The Dilon MBI Procedure

With MBI, the patient receives a pharmaceutical tracing agent that is absorbed by all the cells in the body. Due to their increased rate of metabolic activity, cancerous cells in the breast absorb a greater amount of the tracing agent than normal, healthy cells.  Therefore, malignant cells generally appear as “dark spots” on the MBI image.

A small amount of Sestamibi is injected into the patient, and within minutes the scan can begin. Each breast is immobilized using minimal pressure applied by the Clearshield and imaging is conducted in the standard mammography positions. Patients find the exam to be very comfortable as they are seated throughout the process. The high quality images are immediately available for the physician’s interpretation.
