3D multi-planar reformat of a CCMRA in a patient with exertional chest pain on a background of hypertension and type 2 diabetes mellitus. Orthogonal views in Panel A and B, cross section views in Panel C and D. There is no significant disease in the proximal LM (green dashed line), but there is greater than 50% stenosis in the distal left main coronary artery (LM) (red arrow). These findings were confirmed during invasive coronary angiography (Panel E and Additional file 3: Video S3)
