New techniques, distinctive population, unique normal databases

Attenuation correction in multipinhole-CZT gamma camera

“…System-specific normal databases must be developed. 8 Quantitative software with normal databases developed for the multi-pinhole system has been shown to give quantitative sensitivity comparable to an experienced reader. Adding attenuation correction may help improve the quantitative specificity without loss of sensitivity.…”

Effect of reduced photon count levels and choice of normal data on semi-automated image assessment in cardiac SPECT: Doing more with fewer counts

“…Normal databases should match the study's imaging system, reconstruction software, radiopharmaceutical, and be representative of the patient population. 4,9 ASNC has provided guidance for the optimal performance of nuclear cardiology with SPECT. 10,11 A recent ASNC information statement gives recommendations on technology and imaging protocols that should be considered standard-of-care today.…”
