To evaluate patient acceptance of noninvasive imaging tests for detection of coronary artery disease (CAD), including single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI), stress perfusion magnetic resonance imaging (MRI), coronary CT angiography (CTA) in combination with CT myocardial stress perfusion (CTP), and conventional coronary angiography (CCA).
Intraindividual comparison of perception of 48 patients from the CORE320 multicentre multinational study who underwent rest and stress SPECT-MPI with a technetium-based tracer, combined CTA and CTP (both with contrast agent, CTP with adenosine), MRI, and CCA. The analysis was performed by using a validated questionnaire.
Patients had significantly more concern prior to CCA than before CTA/CTP (p < 0.001). CTA/CTP was also rated as more comfortable than SPECT-MPI (p = 0.001). Overall satisfaction with CT was superior to that of MRI (p = 0.007). More patients preferred CT (46 %; p < 0.001) as a future diagnostic test. Regarding combined CTA/CTP, CTP was characterised by higher pain levels and an increased frequency of angina pectoris during the examination (p < 0.001). Subgroup analysis showed a higher degree of pain during SPECT-MPI with adenosine stress compared to physical exercise (p = 0.016).
All noninvasive cardiac imaging tests are well accepted by patients, with CT being the preferred examination.
• A variety of cardiac imaging tests is available without known patient preference
• CTA/CTP shows a lower degree of concern than conventional coronary angiography
• CTA/CTP shows higher overall satisfaction compared to stress perfusion magnetic resonance imaging
• CTA/CTP is rated as more comfortable than SPECT-MPI
• CTA/CTP is the preferred cardiac imaging test

Institutional master research agreements exist with Siemens Medical Solutions, Philips Medical Systems, and Toshiba Medical Systems. The terms of these arrangements are managed by the legal department of Charité – Universitätsmedizin Berlin. The CORE-320 study has received funding from Toshiba Medical Systems. Two of the authors (FR, RR) have significant statistical expertise. Institutional review board approval was obtained. Written informed consent was obtained from all patients in this study.
The study subjects or cohorts have not been previously reported in regards to patient acceptance. The CORE-320 main study publication in regards to diagnostic accuracy has been published recently be Rochitte et al. (Eur Heart J 2014) and this is a single-centre substudy on the intraindividual patient perception of four cardiac imaging tests. Methodology: prospective, non-randomised controlled trial / intraindividual comparison, performed at one institution.
