Improved Quantitative SPECT Myocardial Uniformity of Myocardial Uptake Using a Half-Time, Iterative Resolution Recovery Algorithm

Authors: James A. Case, PhD; Jessica Jensen; Staci A. Courter; Paul Helmuth; Timothy M. Bateman

Introduction: Iterative resolution recovery methods have been used for reducing patient dose and improving laboratory efficiently. Validation techniques of these methods that depend on visual inspection of the images are prone to reader bias and hard to reproduce. We examined the quantitative uniformity of the myocardial counts following reconstruction using OSEM with resolution recovery (RR-OSEM) vs filtered backprojection (FBP) at full- and half-time acquisition times. 

Methods: We examined twenty-six patients (21 male, BMI=29+/5) with a ECG-gated myocardial perfusion SPECT study acquired on a CardioMD (Philips) SPECT camera. Data was acquired in a 128×128 acquisition matrix (3.2 mm pixel size, 64 angles). Half-time data sets were created by summing only half of the gated frames. Raw datasets were reconstructed using FBP and RR-OSEM. Data sets were post-filtered using a 5th order, 0.4 Nyquist Butterworth filter. To reduce the influence of variations in perfusion uptake, the image was measured using a previously validated frequency domain masking technique. This technique performs a Fourier transform of the image and then removes the object by masking the lower frequency components. By performing an inverse Fourier transform on the masked frequency data, a “noise only” image can be made. The signal to noise ratio (SNR) was calculated as mean deviation of the myocardial ROI divided by the standard deviation (noise) in the same ROI in the frequency domain masked image. 

Results: The signal to noise is summarized in Table 1. The square of the SNR in the half-time FBP reconstructions decreased by a factor of 0.56+/-0.11 when compared to the full-time FBP reconstruction. RR-OSEM half-time reconstructions were more stable, decreasing only by a factor of 0.87+/-0.18 vs. the full-time RR-OSEM reconstruction (p<10-15 FBP vs RR-OSEM).

Conclusions:  The quantitative signal to noise was significantly higher with RR-OSEM vs conventional FBP reconstruction. Furthermore, changes in signal to noise were significantly less when going from full-time to half-time imaging.

The program will allow attendees who are interested in starting or expanding a cardiac PET program to visit St. Luke’s Mid America Heart Institute, review the work flow and instrumentation, ask questions of experienced technologists, and review a few cases, including absolute quantitation of myocardial blood flow.

Feeling unprepared to participate in Medicare’s new Merit-based Incentive Payment System?  Look no further!


The Centers for Medicare and Medicaid Services (CMS) has established 2017 as a transitional year and allow minimal reporting for clinicians to avoid a downward payment adjustment.  


The American Medical Association (AMA) has developed a number of resources including a video entitled, “One patient, one measure, no penality:  How to avoid a Medicare payment penalty with basic reporting,” to provide guidance.

Still have questions?  Contact CVIT at 816-531-2842 x 107.  We are here to help!
