123-Iodine: a new isotope for functional renal scanning

The results are presented of functional renal scanning in 11 urological patients using 123-iodine labelled Hippuran--a new radiopharmaceutical. The 123-iodine isotope possesses distinct advantages over existing isotopes, permitting high resolution imaging whilst delivering a low integrated radiation dose. It is hoped that the expense of this cyclotron-produced isotope will not mitigate against full evaluation of its promising potential.
