NEMA Updates Performance Parameters for SPECT Scanners

Press Release Summary:

NEMA Published NEMA NU 1-2018 (SPECT), a grade which provides a uniform and consistent method for measuring and reporting performance parameters of SPECT scanners. Updates have been done for pixelated detectors, image quality metrics and co-registration accuracy between the CT and SPECT components of a hybrid SPECT/CT scanner.


Original Press Release:

Standard Defines Measurement Methods for Performance Parameters of SPECT Scanners

Revisions include new tests in response to updated technology

ROSSLYN, Va., June 24, 2019—The National Electrical Manufacturers Association (NEMA) published NEMA NU 1-2018 Performance Measurements of Single Photon Emission Computed Tomograph (SPECT), a Standard that provides a uniform and consistent method for measuring and reporting performance parameters of SPECT scanners. Included are updates for SPECT/CT system, pixelated detectors, and a general edit of the entire document to improve readability.

The document has been updated in response to developments in the technology of the scanners, including:

  • A measurement of detector characterization for pixelated detectors
  • Image quality metrics updated to accommodate iterative reconstruction
  • The co-registration accuracy between the CT and SPECT components of a hybrid SPECT/CT scanner

“NU 1-2018 addresses new technology in the SPECT arena, with objective comparisons for SPECT/CT systems and pixelated detectors, such as CZT,” said Jean-Paul Bouhnik, Chief Physicist, Molecular Imaging for GE Healthcare. “Hopefully, this will facilitate the task to objectively compare scanners during the purchasing decision process and after delivery. It defines tests that ensure that a quality system has been delivered.”

NEMA NU 1-2018 is available in hard copy and as an electronic download for $144 on the NEMA website.
