The value of myocardial perfusion imaging with Tc-99m MIBI for the prediction of perfusion improvement after percutaneous transluminal coronary angioplasty
Introduction: Percutaneous transluminal coronary angioplasty (PTCA) is an effective method for revascularizing of stenotic coronary vessels. Lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. Introduction of a noninvasive metho...
متن کاملThe truncation artifact in a skinny patient following myocardial perfusion SPECT
Myocardial perfusion SPECT is one of the most common imaging techniques performed in nuclear medicine departments. To avoid misleading interpretation, it is necessary to address the quality control and technical problems. The truncation artifact occurs when the patient size is large relative to the field of view of the camera, causing false perfusion defects in the LV myocardium, misinterpreted...
متن کاملMyocardial Perfusion SPECT Imaging in Dextrocardia with Situs Inversus: A Case Report
Dextrocardia is a cardiac positional anomaly in which the heart is located in the right hemithorax with its base-to-apex axis directed to the right and caudad. Situs inversus is an autosomal recessive disorder that causes organs in the chest and abdomen to be positioned in a mirror image from their normal position. Dextrocardia may occur in isolation or as part of situs inversus. Similarly, sit...
متن کاملComparison of dipyridamole – induced electrocardiographic changes and myocardial perfusion imaging in diagnosis of coronary artery disease [Persian]
Introduction: This study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ECG) cahnges, comparing with myocardial perfusion imaging. Materials and Methods: 222 patinets were studied with dipyridamole infusion (based on ECG criteria) as well as Dipyridamole-myocardial perfusion imaging (MPI). Results: Abnormal dipyridamole test and abnormal MPI were noted in 1...
متن کاملCovid-19 manifestation on Tl-201 myocardial perfusion SPECT/CT
A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...
متن کاملTranslation of Methdology used in Human Myocardial Imaging to a Sheep Model of Acute Myocardial Infarction
Background: Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI) could be used for assessing sheep myocardium following an acute myocardial infarction (MI) and response to int...
