研究概览
简要总结
· After all the approvals sample size screening will be executed with respect to inclusion and exclusion criteria.
· All the procedure will be explained to the patient and breath bold instructions should be given and heart rate should be monitored.
· All the demographic details will be collected.
· Scan will perform using the standard operating protocol
· The best cardiac phase with least motion artifact will be reconstructed with respect to R-R interval.
· The best Phase will be selected and reconstructed using filtered back and iterative (idose level 3) reconstruction algorithm by keeping the filter CB constant
· All the images will be then transferred to ISP server for image analysis.
· Image will be analysed qualitatively and quantitively. For quantitative analysis ROI will be placed LM, RCA, LAD, LCX and Major branch to calculate CNR, SNR and image noise.
· For qualitative analysis images will be accessed by two Radiologist without revealing the reconstruction technique to access image quality.
