Diagnositic value of dobutamine and atropine 99mTc-MIBI myocardial perfusion imaging for coronary artery disease

OBJECTIVE?To study the diagnostic value of dobutamine-atropine 99m Tc-MIBI myocardial perfusion imaging for coronary artery disease.?METHODS?The myocardial perfusion imaging was performed by intravenous injection of 99m Tc-MIBI at increasing dobutamine dose grade and intervention of dobutamine and atropine. ?RESULTS?The sensitivity of dobutamine and dobutamine-atropine 99m Tc-MIBI myocardial perfusion imaging for coronary artery disease were 81%(18/22) and 95%(21/22) respectively, and the severity adverse reaction could not be found during the whole process of examination. ?CONCLUSION? After adding atropine, the dobutamine 99m Tc-MIBI myocardial perfusion imaging can raise the sensitivity of diagnosis and that is a safety and effective method for the patients with coronary artery disease which cann't live up to advance heart rate because of different cause.
