评价了二亚乙基三胺五乙酸钆（DTPA）对磁共振（MR）成像后进行的计算机断层扫描（CT）研究的影响。两种Gd-DTPA溶液的CT扫描显示实质性衰减。2例Gd-DTPA增强后行CT检查的患者，在膀胱和肾集合系统可见高密度Gd-DTPA。然而，在目前用于MR成像的浓度下，Gd-DTPA仅导致肾皮质轻微增强。
An evaluation was done of the effect of gadolinium diethylenetriaminepentaacetic acid (DTPA) on computed tomographic (CT) studies performed after magnetic resonance (MR) imaging. CT scans of two solutions of Gd-DTPA demonstrated substantial attenuation. In two patients who underwent CT after Gd-DTPA-enhanced MR imaging, the high attenuation of concentrated Gd-DTPA was seen in the urinary bladder and renal collecting system. However, in the concentration presently used in MR imaging, Gd-DTPA results in only minor enhancement of renal cortex.
