OBJECTIVES The purpose of this study was to evaluate the prognostic value of community-based myocardial perfusion imaging (MPI) and to assess the incremental value of individual components of (99m)Tc-sestamibi single photon emission computed tomography (SPECT). BACKGROUND Although the most rapid growth of MPI has been in community outpatient laboratories, its prognostic value has not been val...

Emergency room evaluations of patients presenting with chest pain continue to rise, and these evaluations which often include cardiac imaging, are an increasing area of resource utilization in the current health system. Myocardial perfusion imaging from the emergency department remains a vital component of the diagnosis or exclusion of coronary artery disease as the etiology of chest pain. Rece...

BACKGROUND We wanted to evaluate the presense of myocardial ischaemia in asymptomatic patients with high cardiovascular risk, the influencing clinical and laboratory factors and the impact of ischaemia on final management decision. MATERIAL AND METHODS We evaluated 60 asymptomatic patients with high CV risk, who underwent SPECT myocardial perfusion imaging (MPI) for detection of suspected CAD...

background & aim : primary dysmenorrhea (pd) is the most common genital disease among adults which can disrupt daily activities and reduce quality of life. acupressure was recommended for relief of pd and the aim of this study was to compare the maximum pain intensity (mpi) and duration of pd after acupressure on third liver (liv3) and placebo points. methods & materials : students who were suf...

Background In myocardial perfusion imaging (MPI), highly accelerated acquisition can be used towards reducing the compromises in the image quality (spatio-temporal resolutions, volume coverage, SNR) routinely observed with the current clinical protocols. In this study, we demonstrate the feasibility of a recent accelerated dynamic MRI scheme, k-t SLR (based on sparse and low rank properties) (L...

PURPOSE Several studies have suggested that a combined approach of stress myocardial perfusion imaging (MPI) and coronary computed tomography angiography (CCTA) can provide diagnostic results with excellent accuracy. We aimed to explore whether the addition of CCTA to stress MPI provides incremental diagnostic value in intermediate-to-high cardiovascular risk patients. METHODS A total of 106 ...

OBJECTIVE The aim of this study was to investigate the relationship between patient characteristics and adenosine-related side-effects during stress myocard perfusion imaging (MPI). The effect of presence of adenosine-related side-effects on the diagnostic value of MPI with integrated SPECT/CT system for coronary artery disease (CAD), was also assessed in this study. METHODS Total of 281 pati...

Background. Worldwide, coronary artery disease (CAD) is a leading cause of mortality and morbidity remains to be top health priority in many countries. A non-invasive imaging modality for diagnosis CAD such as single photon emission computed tomography-myocardial perfusion (SPECT-MPI) usually requested by cardiologists it displays radiotracer distribution the heart reflecting myocardial perfusi...

PURPOSE To investigate the incremental diagnostic value of dual-bolus over single-contrast-bolus first pass magnetic resonance myocardial perfusion imaging (MR-MPI) for detection of significant coronary artery disease (CAD). MATERIALS AND METHODS Patients (n = 49) with suspected CAD underwent first pass adenosine stress and rest MR-MPI and invasive coronary angiography (CA). Gadolinium diethy...

Coronary artery disease (CAD) remains the leading cause of death and morbidity worldwide. To date, diagnostic evaluation of patients with suspected CAD has relied upon the use of physiologic non-invasive testing by stress electrocardiography, echocardiography, myocardial perfusion imaging (MPI) and magnetic resonance imaging. Indeed, the importance of physiologic evaluation of CAD has been high...
