Crucial stenosis affected the left anterior descending (LAD) artery in 14 cases, the left circumflex (LCX) artery in 11 cases as well as the right coronary artery (RCA) in ten circumstances. There were no findings of critical stenosis within the coronary arteries from the remaining 34 patients. The time span in between MPI and coronary angiography didn’t exceed 3 months.J. Pers. Med. 2021, 11,3 of2.1. Patient Preparation and Information Acquisition Before the study, each and every patient followed the routine protocol of preparation for the MPI performed with all the dipyridamole strain test. Therapy with drugs that may well interfere using the MPI was suspended for an acceptable period prior to the study. Calcium antagonists and nitrates had been discontinued 2 days prior to the studies, and trimetazidine and its derivatives had been discontinued for 7 days. Additionally, sufferers had been advisable to discontinue medication and prevent beverages and foods containing methyloxnatines (for instance caffeine or theophylline) for two days prior to the dipyridamole pharmacological test. Patients have been also asked to consume a sandwich with cheese or maybe a hard-boiled egg right away prior to the study, to accelerate hepatic clearance on the radiopharmaceutical agent. MFR was assessed applying a CZT Discovery NM530c camera (GE Healthcare, Chicago, IL, USA) inside a two-day protocol–at rest and soon after the pharmacological test with dipyridamole. Each time the patient was first administered intravenously 37 MBq of 99m Tc-MIBI (for positioning around the camera, with all the heart within the center in the field of view of detectors) followed by 550 MBq inside a rapid bolus injection, carried out at the same time as the get started of image acquisition. dynamic image acquisition continued for 8 min. The stress part of the study consisted of a pharmacological test with dipyridamole, administered intravenously (dose: 0.56 mg/kg), right after positioning the patient around the camera. The radiopharmaceutical bolus was administered 3 min just after the injection of dipyridamole. 2.two. Information Processing Information acquired making use of the gamma camera incorporated dynamic pictures in listmode format, without having attenuation correction.
