Does gadolinium appear on CT?

Gadolinium, like iodine, is a heavy metal that attenuates X-rays. The atomic number of gadolinium (Z=64) is higher than that of iodine (Z=53). The k-edge of gadolinium is also closer to the peak of the CT spectrumwhich means that gadolinium absorbs more of the X-ray beam than iodine.
