Abstract：
:Serious adverse reactions following the IV administration of Gd-DTPA (Magnevist, gadopenetate dimeglumine, Berlex Laboratories, Wayne, NJ), although extremely rare, can occur. As yet, there has been no published case of a severe anaphylactoid-type reaction to Gd-DTPA.

杂志文章abstract：:The fast Fourier flow technique offers a convenient way for extremely exact flow measurements. In combination with ECG gating, arterial flow can be studied. The total acquisition time for a single measurement is about 10 s, an ECG-gated cine sequence can be acquired in about 4 min. Fast Fourier flow can, therefore, be...
