Nucl. Med. Technol.1975 Sep 01; 3 AB - Brain scans were performed using the following methods: (A) oral administration of perchlorate at least 30 min before i.v. injection of 99mTc-pertechnetate (99mTcO4 –) and (B) simultaneous administration of oral perchlorate and i.v. 99mTcO4 –. The scans were retrospectively reviewed for choroid plexus uptake of technetium and scan quality. The simultaneous administration of oral perchlorate and i.v. 99mTcO4 – is an effective method of performing brain scans and should replace outdated protocols requiring treatment with perchlorate before i.v. administration of pertechnetate.
