title: [Clinical evaluation of 99mTc-hexakis 2-methoxy isobutyl isonitrile (MIBI): multicenter phase III clinical trial].
abstract: Multicenter Phase III clinical trial on a new myocardial imaging agent, 99mTc-hexakis 2-methoxy isobutyl isonitrile (99mTc-MIBI), was carried out in 464 patients with various cardiac disorders. Both planar and tomographic images provided high-quality regional myocardial perfusion images which correlated well with 201TlCl images. The positive ratios of myocardial infarction and angina pectoris by the agent were as high as that of 201TlCl. In addition, ventricular function and wall motion could be assessed with first-pass and ECG gated studies. There was no serious adverse reaction which were attributed to 99mTc-MIBI in any of patients studied. A transient metallic taste was observed immediately after the injection in approximately 64% of the patients. Based on its safety and efficacy, the clinical usefulness of 99mTc-MIBI was observed in 562 (93.1%) of 604 injections. In conclusion, 99mTc-MIBI was useful as a imaging agent of myocardial blood flow.
