Flow chart showing the patient selection strategy for comparison of diagnostic performance and radiation dose of MSR and HSR of myocardial CTP imaging datasets in patients with suspected or known CAD. The study population for intraindividual comparison of diagnostic performance consisted of 93 of 134 patients with multisegment acquisition of stress CTP allowing both HSR and MSR. The remaining 41 of 134 patients had predefined single-segment acquisition due to heart rates < 65 bpm, and only HSR was possible. These patients served as a control group for interindividual radiation dose comparison. bpm Beats per minute, CAD Coronary artery disease, CTP Computed tomography perfusion, HSR Halfscan reconstruction, MSR Multisegment reconstruction
