Myocardial perfusion imaging with SPECT remains critically important for diagnosing,
assessing, and evaluating treatment of coronary artery disease. However, conventional …

Investigators in nuclear medicine have long been in search of a practical method to increase
the number of detected events in cardiac SPECT. A clinically practical method requires a …

Siemens has developed a new IQ-SPECT™ product to improve the efficiency of myocardial
perfusion imaging (MPI) using conventional large-field-of-view SPECT and SPECT/CT …

Background We have recently validated a quarter-time protocol in Myocardial Perfusion
Imaging named IQ-SPECT, whose basic principle is to implement a multifocal collimator; …

Background High-resolution single photon emission computed tomography (SPECT) with a
pinhole collimator is a new method for evaluating the regional properties of …

The IQ· SPECT system was introduced by Siemens in 2010 to significantly improve the
efficiency of myocardial perfusion imaging (MPI) using conventional, large field-of-view …

A triple-detector, multipinhole SPECT system was optimally configured to perform
simultaneous 201Tl (stress)/99mTc (rest) myocardial perfusion imaging (MPI) using a …
