RT Journal Article SR Electronic T1 Efficacy of Administering Simultaneous Oral Perchlorate and Intravenous 99m TcO4 for Brain Scanning JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 138 OP 140 VO 3 IS 3 A1 Maxwell, Mary E. A1 Baggenstoss, Bonnie J. YR 1975 UL http://tech.snmjournals.org/content/3/3/138.abstract 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of oral perchlorate and i.v. 99mTcO4 – is an effective method of performing brain scans and should replace outdated protocols requiring treatment with perchlorate before i.v. administration of pertechnetate.
