RT Journal Article SR Electronic T1 123I-MIBG Imaging: Patient Preparation and Technologist’s Role JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 82 OP 86 DO 10.2967/jnmt.115.158394 VO 43 IS 2 A1 S. Seth Van Vickle A1 Randall C. Thompson YR 2015 UL http://tech.snmjournals.org/content/43/2/82.abstract AB The radiopharmaceutical 123I-metaiodobenzylguanidine (MIBG) was approved by the Food and Drug Administration in March 2013 for the assessment of myocardial sympathetic innervation in the evaluation of patients with heart failure and an ejection fraction of no more than 35%. Almost any well-equipped nuclear medicine or nuclear cardiology laboratory can perform this test, although there is a need for special attention to patient preparation, dose calibration, and proper timing of the image acquisition. This article reviews the role of the nuclear medicine technologist and some practical aspects of cardiac sympathetic 123I-MIBG imaging of which the laboratory team needs to be mindful.
