Advances in SPECT camera software and hardware: Currently available and new on the horizon

  • E. Gordon DePueyEmail author
Review Article

Introduction

A long-standing limitation of radionuclide myocardial perfusion SPECT is its relatively lengthy acquisition time, as compared to stress echocardiography and cardiac CT. The American Society of Nuclear Cardiology (ASNC) and the Intersocietal Commission for the Accreditation of Nuclear Medicine Laboratories (ICANL) have rightfully insisted that acquisition times not be decreased below those set forth in the ASNC Guidelines so that adequate image counting statistics are maintained, thereby maintaining test sensitivity and minimizing artifacts associated with low count density studies. New software methods and new innovative hardware described below, however, now allow for significantly shortened SPECT acquisition times without a decrease in image quality.

More recently, the media, the public, and the medical community have drawn attention to patient radiation exposure associated with radiographic, nuclear medicine, and nuclear cardiology procedures and the...
