Blood Oxygen Level-Dependent (BOLD)-MRI was performed to evaluate myocardial oxygenation18 (link)-22 (link). Briefly, under 1-2% isoflurane anesthesia, pigs were positioned in the MRI scanner (Signa Twin Speed EXCITE 3T system, GE Healthcare, Waukeshau, WI) and BOLD images (4-5 axial-obeselique) acquired along the cardiac short axis during suspended respiration. Gated Spoiled Gradient Echo (SPGR) sequence with TR/TE/number of echoes/Matrix size/FOV/Slice thickness/Flip cardiac angle = 20.5 ms/2 ms/8/128x128/35/0.5 cm/30°. Imaging was repeated during intravenous injection of adenosine (400 μg/kg/min) through an ear vein catheter. BOLD data was processed in MATLAB 7.10 (The MathWorks Inc., Natick, MA). The BOLD index, R2*, was estimated in each voxel by fitting the MR signal intensity vs. echo time to a single exponential function and calculating the MR intensity decay rate. Myocardial R2* values were estimated from regions of interest (ROI) defined based on T2*-weighted MR images and calculating R2* weighted-average of all ROIs.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
