Siemens ECAT EXACT 47


Siemens ECAT HR+


New Developments in Nuclear Imaging

Nuclear Imaging Services is proud to offer quality refurbished PET systems. The systems selected by NIS for refurbishment are inspected piece-by-piece, refurbished in-house to OEM specifications, and meticulously tested to ensure the highest quality equipment is put into service. Every refurbished unit is fully warranted and supported.

Utilizing state of the art electronics upgrades and current releases of PET perfusion software, NIS provides high quality refurbished units that are equipped to acquire and process images with Medical Imaging Electronics’ ECAT Scintron, the first and only upgrade path available to the Siemens ECAT 47, ECAT HR+, and ECAT Accel PET systems.

Advantages of Cardiac PET Perfusion Imaging vs. Traditional Myocardial Perfusion Imaging

PET has better spatial resolution than SPECT Theoretical tomographic in-plane spatial resolution of PET is 2 to 4 mm, as compared with 6 to 8 mm for TC-99m SPECT.

  • Improved efficiency(complete study takes approximately 35 min vs. 3.5hrs)
  • Improved resolution(imaging with 511 kev vs. 140 kev)
  • Fewer attenuation artifacts1
  • Greater sensitivity and specificity (fewer false positives and false negative results)
  • Increased detection of patients with triple vessel disease
  • Shorter half life of isotope (75 seconds vs. 6 hrs)
  • Lower radiation exposure(0.26 rem vs. 1.44 rem per Oak Ridge Institute for Science & Education)
  • Stress method (pharmacologic vs. treadmill)
  • Increased detection of patients with triple vessel disease
  • Radiopharmaceutical availability (onsite generator vs. delivery of unit doses)
  • Now reimbursed for similar ICD-9 codes as general MPI studies with approximately double the reimbursement (reimbursement varies depending on region: CPT codes used 78492, A9555 (x2/patient), 78499 or (78478 & 78480), 93015)
