Fig. 1A. 55-year-old man with three-vessel coronary artery disease.
Arrows indicate coronary sinus. T1-weighted gradient-echo MR image shows
coronal scout image of coronary sinus. White line was set horizontally through
coronary sinus.

Fig. 1B. 55-year-old man with three-vessel coronary artery disease.
Arrows indicate coronary sinus. T1-weighted gradient-echo MR image obtained at
level indicated by white line in A shows axial scout image of coronary
sinus. White zigzagged line was set perpendicularly through coronary sinus 1-2
cm proximal to right atrium.

Fig. 2. Graph shows correlation of myocardial blood flow
(mL·g-1·min-1) when measured using MR
imaging and positron emission tomography. Both baseline and hyperemia results
are included. Relatively good agreement between measurements was found;
r=0.80, p<0.01, y=0.83 x +0.04.

Fig. 3. Graph shows correlation of global coronary flow reserve as
measured using MR imaging and positron emission tomography. Only moderate
correlation was found between coronary flow reserve measurements provided by
each modality; r = 0.50, p < 0.01, y = 1.12
x +0.06.
