Files in this Data Supplement:
S2B, Cine image in arterial phase shows akinesia over infralateral wall of left ventricle.
S2E, Cine image of coronary angiography shows exactly the same coronary findings as MDCT: obstruction of distal circumflex artery and faint enhancement of terminal branch.
S5B, Four-chamber cine image shows dilated right ventricle, especially when compared with left ventricle. Note slow filling in early diastole (passive filling phase) and fast filling in late diastole (atrial kick phase), which indicate diastolic dysfunction.
S5C, Short-axis cine image shows cardiac motion on which blood volume-versus-cardiac phase plot was based. Note slow filling in early diastole (passive filling phase) and fast filling in late diastole (atrial kick phase), which indicate diastolic dysfunction.
S5D, For comparison, note this short-axis cine image in another patient of similar age (77 vs 76 years old) and ejection fraction (60.1% vs 62.3%). Also notice the fast filling in early diastole (passive filling phase) and slow filling in late diastole (atrial kick phase), which indicate normal diastolic function.
S6A, 56-year-old man with ischemic heart disease and left ventricular remodeling and dilatation. Cine image in mitral view shows mitral tethering. This condition leads to poor coaptation between the two leaflets of the mitral valve, and mitral regurgitation is expected. Rigid and limited motion of mitral valve can be clearly visualized in this cine image.
S6B, Cine image of postoperative cardiac CT in mitral view in same patient as in A shows disappearance of angle and good coaptation. With reduction of diameter of mitral annulus by mitral ring, chordae tendineae no longer tether anterior leaflet of mitral valve. Good motion of mitral valve is seen. This case shows that MDCT can be used even in visualizing valves and chordae tendineae.
S6C—21-year-old woman with exertional dyspnea who is suspected of having ischemic heart disease. Cine image in three-chamber view shows thickening and poor coaptation of aortic valve. When aortic valve looks somewhat unusual, further evaluation focusing on aortic valve should be undertaken.
S7B, Midventricular hypertrophic obstructive cardiomyopathy in 72-year-old woman with exertional dyspnea. Horizontal long-axis cine image shows “kissing” of midventricular myocardium and lumen obliteration, making only basal heart an effective chamber.
S7E, Arterial phase cine image in 42-year-old woman with lupus microangiopathy who presented with exertional dyspnea. Cine image shows akinetic motion and muscle thinning over lateral wall. Because overlying coronary artery is normal, infarction is considered to be related to capillary damage due to lupus activity. If only coronary arteries are interpreted, patient’s diagnoses might be delayed until cardiac MRI and catheter coronary angiography are performed.
