The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

Capitol's Vintage Collections CD is the best single-disc overview of Jackson's most essential rockabilly and country recordings for Capitol from 1956 through 1961, surveying Jackson in a variety of modes, from full-throttle rock ("Let's Have a Party," originally recorded by Elvis Presley and featured in the film Loving You) to rockabilly to traditional country (the weeper "Why I'm Walkin'" gets over via a vocal imbued with the profound sadness so characteristic of Patsy Cline's great tearjerkers).
