Rest … WebPatient motion during myocardial perfusion SPECT is a common source of errors. The extent and severity of motion artifacts have been described for filtered backprojection (FBP) reconstruction. In recent years, iterative reconstruction has been used increasingly in reconstruction of myocardial perfusion SPECT images and has been shown to be more …

WebJun 7, 2024 · Cardiac gated SPECT in both 16 and 8 framing simultaneously and both stress and rest phases at one-day protocol was performed for 50 patients. Data have been reconstructed by filter back projection (FBP) method and left ventricular (LV) systolic parameters were calculated by using QGS software. WebMar 12, 2013 · Our quantitative analysis showed that the scores for SSS, SRS, stress and rest TPD, stress and rest EDV, and stress and rest ESV were higher with the AS processing method than with the FBP processing method; however, this was not the case for SDS, TID, or EF for the full-dose group or half-dose group. fiber labs tests
Interpretation of SPECT/CT Myocardial Perfusion Images …
WebThe FBP images were created with a 10th-order Butterworth filter, using different cutoff frequencies for the ungated (0.4 cycles/cm) and gated (0.35 cycles/cm) data. The OSEM iterative reconstruction (2 iterations, 10 subsets) was done both with CT-based AC … WebJun 23, 2009 · Ninety (82%) of the half-time 16-frame-gated acquisitions were scored as excellent or good in quality, compared to 93 (85%) of the stress FBP-gated acquisition images (P = . 59). The major cause (80%) of fair or poor quality of the 20 half-time-gated images was suboptimal count statistics. Interpretive Certainty WebBackground: The aim of this study was to analyze different prognoses in women and men with normal myocardial perfusion gated SPECT, according to stress test results. Results: Four hundred and seven patients (16.9%) (15.9% women and 17.5% men) had a … derbyshire oatcakes by post
