Abstract

For the in vivo relaxivity of Gd-DTPA at 6.3 T in rat muscle a value of 2.7±0.5 (mM s)−1 was found, and for the in vitro value in water 3.00±0.56 (mM s)−1 at 37°C. The temperature dependence of the in vitro relaxivity was −0.087 (mM s °C)−1. The relation between1/T 1 and the tissue Gd-DTPA concentration is linear for the normally used in vivo Gd-DTPA concentration range
