Does tissue edema change gadolinium-diethylenetriamine pentaacetic acid ( Gd-DTPA ) -enhanced T1 relaxation times of viable myocardium?
Tissue edema in the viable myocardium does not increase the relative distribution volume of the contrast agent. As a result, edema does not change Gd-DTPA-enhanced T1 relaxation times of the viable myocardium.
Increasing serum creatinine values are associated strongly and independently with CHD risk in men but not in women in whom the risk curve is U-shaped. The phenomenon of low creatinine levels underlies some hitherto unexplained relevant observations, and low measurements may be attributed to inassayability secondary to involvement in autoimmune activation.
