This study hypothesizes that renal transplantation candidates are diagnosed with significant Coronary Artery Disease (CAD) equal with non-invasive modalities as with invasive modalities. Therefore the investigators are investigating the ability of coronary computed tomographic angiography (cCTA), myocardial perfusion scintigraphy (MPS), acoustic CAD Patch and combination hereof to detect CAD as defined by invasive Coronary angiography (CAG).
