‏‎despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...

BACKGROUND Although pharmacologic stress myocardial perfusion imaging (MPI) and exercise stress MPI have comparable diagnostic accuracy, their comparative value for risk stratification of patients with known or suspected coronary disease is not known. METHODS AND RESULTS The data of 14,918 patients were combined from 24 studies evaluating prognosis in patients undergoing either pharmacologic ...

Background False positive nuclear stress myocardial perfusion imaging(MPI) findings are known to occur in obese patients and women with large breasts due to attenuation artifact. A false positive MPI study may lead to unnecessary coronary arteriography(Cath). CMR stress perfusion imaging is not affected by obesity and has better spatial resolution than MPI, without radiation exposure. The CE-MA...

BACKGROUND American College of Cardiology/American Heart Association appropriate use criteria recommend performing stress myocardial perfusion imaging (MPI) for intermediate- to high-risk patients presenting with syncope but not for low-risk patients. However, there are limited data to support these recommendations. We investigated the yield of stress MPI for the evaluation of syncope in patien...

Background—ACC/AHA Appropriate Use Criteria recommend performing stress MPI for intermediate to high-risk patients presenting with syncope, but not for low-risk patients. However, there are limited data to support these recommendations. We investigated the yield of stress MPI for the evaluation of syncope in patients at risk but without known CAD Methods and Results—From the Cleveland Clinic IR...

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...

BACKGROUND The myocardial performance index (MPI) first described by Chuwa Tei in 1995 is a relatively new echocardiographic variable used for assessment of overall cardiac function. Previous studies have demonstrated the MPI to be a sum representation of both left ventricular systolic and diastolic function with prognostic value in patients with coronary artery disease as well as symptomatic h...

OBJECTIVE To determine the outcomes of patients with chest pain (CP) and prior history of coronary artery disease (CAD) managed with observation followed by outpatient stress myocardial perfusion imaging (MPI). METHODS Retrospective analysis of patients with CP managed with observation followed by outpatient stress MPI, comparing cardiovascular (CV) event rates stratified by CAD history. RE...

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...

This document from the American Society of Nuclear Cardiology represents an updated consensus statement on the evidence base of stress myocardial perfusion imaging (MPI), emphasizing new developments in single-photon emission tomography (SPECT) and positron emission tomography (PET) in the clinical evaluation of women presenting with symptoms of stable ischemic heart disease (SIHD). The clinica...
