Paramagnetic contrast agents

NMR is an important teclnhque for the study of flow and diflfiision, since the measurement may be made highly sensitive to motion without in any way influencing the motion under study. In analogy to many non-NMR-methods, mass transport can be visualized by imaging the distribution of magnetic tracers as a fiinction of time. Tracers may include paramagnetic contrast agents which, in particular, reduce the transverse... [Pg.1534]

The original work of Swift and Connick [82] paved the way for modern applications of this NMR method in paramagnetic contrast agent research. The Lausanne group of Merbach and co-workers have developed elegant applications of the method [83]. Most frequently, the difference between the transverse relaxation rates of 170 in reference buffer (1/T2A) and in solutions containing the BPCA (1/T2) are measured as a function of temperature. The analysis fits the temperature dependence of the reduced transverse relaxation rate, 1/T2R, defined as ... [Pg.226]
