“…Values of SSS, SRS and SDS on stress-rest Tl-201 gated SPECT were automatically calculated with QPS and HSV using a normal database developed for Japanese patients. 13) Reverse redistribution on a rest Tl-201 SPECT image was not reflected in the SDS, and it was considered to be zero. Regional SSS, SRS and SDS in apical, mid and basal areas were also calculated to evaluate the characteristics of each software.…”

SummaryHeart Score View (HSV) is a free software package for automated quantification of myocardial single photon emission computed tomography (SPECT) imaging using a standard Windows computer. We compared scoring results of myocardial perfusion among visual analysis, Quantitative Perfusion SPECT (QPS), and HSV in patients with known or suspected coronary artery disease.This study included 75 consecutive patients with known or suspected coronary artery disease who underwent adenosive stress-rest Tl-201 SPECT. Analysis of myocardial perfusion SPECT was performed on a standard 17-segment model visually and using QPS and HSV.There were 54 male and 21 female patients with a mean age of 70.5 ± 10.7 years. Thirteen patients (17%) had prior myocardial infarction. Summed stress score (SSS) and summed rest score (SRS) in the mid and basal areas were significantly higher on HSV than visual analysis or QPS. There was no significant difference in SDS in the whole area among the 3 methods. Similar results were found even in patients without prior myocardial infarction. Manual setting of the left ventricular cavity improved the correlations of SSS, SRS and SDS between HSV and the other methods.Our data suggested that HSV was comparable with visual analysis or QPS in scoring myocardial perfusion when manual setting of the left ventricular cavity is applied.

“…The severity of the attenuation artifact can be influenced by the energy of the incident photon [19]. Therefore attenuation of 201 Tl is more marked than for 99m Tc [8,20]. Experienced nuclear cardiologists can recognize the artifacts of the inferior wall with information of regional wall motion, differentiating attenuation artifact from myocardial scarring.…”

“…With IQ-SPECT, it is possible to perform MPI scans in one-fourth the time or using one-fourth the administered dose as compared to a standard protocol using parallel-hole collimators [6][7]. In Japan, thallium-201 ( 201 Tl) myocardial perfusion study is conducted in more than 50% of stress examinations [8]. It was reported that there was a significant difference between Japanese and Western populations and that the best diagnostic accuracy was obtained by using the populationand orbit-specific normal database [9].…”

Objective: A novel multifocal collimator, IQ-SPECT (Siemens) consists of cardio-centric and 3D iterative SPECT reconstruction and makes it possible to perform MPI scans in a short time. The aims are to delineate the normal uptake in thallium-201 ( 201 Tl) SPECT in each acquisition method and to compare the distribution between new and conventional protocol, especially in patients with normal imaging.Methods: Forty patients (eight women, mean age of seventy-five years) who underwent myocardial perfusion imaging were included in the study. All patients underwent one-day protocol perfusion scan after an adenosine-stress test and at rest after administrating 201 Tl and showed normal results. Acquisition was performed on a Symbia T6 equipped with a conventional dual-headed gamma camera system (Siemens ECAM) and with a multifocal collimator called IQ-SPECT. Imaging was performed with a conventional system followed by IQ-SPECT/computed tomography (CT).Reconstruction was performed with or without X-ray CT-derived attenuation correction (AC). Two nuclear physicians blinded to clinical information interpreted all MPI studies.A semi-quantitative myocardial perfusion was analyzed by a 17-segment model with a 5-point visual scoring. The uptake of each segment was measured and left ventricular functions were analyzed by QPS software.Results: IQ-SPECT provided good or excellent image quality. IQ-SPECT images without AC were similar to those of conventional LEHR study. Mid-inferior defect score (0.3±0.5) in conventional LEHR study was increased significantly in IQ-SPECT with AC (0±0). IQ-SPECT (AC) improved the mid-inferior decreased perfusion shown in conventional images. The apex in IQ-SPECT (AC) was decreased compared to that in LEHR (0.1±0.3 vs. 0.5±0.7, p<0.05). The left ventricular ejection fraction from IQ-SPECT was significantly higher than that from the LEHR collimator (p=0.0009). Conclusion:The images of IQ-SPECT acquired in a short time are equivalent with that of conventional LEHR. The results indicated that the IQ-SPECT system with attenuation correction is capable of correcting inferior artifacts with high image quality.(Ann Nucl Med)

“…The JSNM working group database for myocardial perfusion tracers was created in 2007, and the characteristics of the database, backgrounds of a low-likelihood of coronary artery diseases, type of tracers and acquisition conditions were described elsewhere [4]. Briefly, the perfusion databases consisted of 326 sets of short-axis images, and they were classified into male/female, 180°/360° and tracer type combinations.…”

“…In the preceding studies, although visual evaluation of extent and severity of ischemia was essential, quantitative analysis aided or enhanced a diagnostic accuracy [1][2][3]. Since appropriate normal databases matching those of the acquisition parameters, genders and types of tracers were considered indispensable, we accumulated normal databases from multiple institutions as the working group activity of the Japanese Society of Nuclear Medicine (JSNM) [4][5][6]. Our aim was to use one common standard database for multiple centers with nuclear medicine facilities.…”

Purpose. The Japanese Society of Nuclear Medicine (JSNM) working group has created a myocardial perfusion imaging database applicable to standard acquisition protocol. The aim of this study is to validate the diagnostic accuracy of the common normal database compared with the expert interpretation of each institute. Methods. Five institutions participated in this study and used different acquisition settings which included 360°/180° rotation, camera configuration and camera orbits. The software and its version used in each institution also varied. The working group database was applied to detect the culprit coronary territory from a total of 166 patients with coronary artery disease (CAD) and 145 patients with low-likelihood of CAD. Results. When summed stress score ≥4 was defined as significant abnormality, overall sensitivity, specificity and accuracy of patient-based analysis were 77%, 72% and 75%, respectively, based on quantitative analysis using the common database, whereas those by institutional visual expert reading were 72%, 79% and 75%, respectively. Conclusion. The common database, which was created by a multi-center working group and separated between male/female with 180/360° acquisitions, demonstrated comparable diagnostic accuracy to expert interpretation by each institute, and it may be applicable to multi-center studies.
