Objective: IQSPECT is an advanced high-speed SPECT modality for performing myocardial perfusion imaging (MPI), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. The aim of this study was to compare IQSPECT compared with conventional SPECT interms of performance based on standard clinical protocols. In addition, we examined the concordance between convention...

malmquist productivity index (mpi) is a numeric index that is of great importance in measuring productivity and its changes. in recent years, tools like dea have been utilized for determining mpi. in the present paper, some models are recommended for calculating mpi when there are just ratio data available. then, using dea and dea-r, some models are proposed under the constant returns to scale ...

Fetal cardiac function is increasingly recognized as a marker of disease severity and prognosis in selected fetal conditions. Magnetic resonance imaging (MRI) has been used in experimental (animal) fetal cardiology but the lack of a noninvasive fetal electrocardiogram (ECG) to trigger image acquisition remains a major limiting factor precluding its application in humans. Fetal medicine speciali...

BACKGROUND Despite substantive growth in utilization of positron emission tomography (PET) myocardial perfusion imaging (MPI), evidence on its prognostic value is limited. We aimed to comprehensively evaluate the prognostic literature of PET perfusion measures according to the most recent American Heart Association recommendations for assessment of novel cardiovascular biomarkers. METHODS We ...

Background There are limited data on the cardiac effects of radiotherapy and chemo-radiotherapy on the heart in patients with non-small cell lung cancer (NSCLC). CART is a pilot and feasibility study designed to investigate change in myocardial function and identify changes in myocardial tissue properties in patients being treated with radical radiotherapy. Patients will undergo cardiac magneti...

BACKGROUND Appropriate use criteria (AUC) have been developed to aid in the optimal use of single-photon emission computed tomography (SPECT)-myocardial perfusion imaging (MPI), a technique that is a mainstay of risk assessment for ischemic heart disease. The impact of appropriate use on the prognostic value of SPECT-MPI is unknown. METHODS AND RESULTS A prospective cohort study of 1511 conse...

Bronchopulmonary dysplasia (BPD) survivors from the surfactant era were evaluated by echocardiography in a few studies and no significant differences were found between BPD and non-BPD children. In this study, we evaluated these children with myocardial performance index (MPI), which was obtained by tissue Doppler echocardiography (TDE) in addition to the conventional methods. Fifteen children ...

Message passing interface (MPI) has been widely used for implementing parallel and distributed applications. The emergence of cloud computing offers a scalable, fault-tolerant, on-demand alternative to traditional on-premise clusters. In this thesis, we investigate the possibility of adopting the cloud platform as an alternative to conventional MPI-based solutions. We show that cloud platform c...

This paper investigates the performance of UNDP multidimensional poverty index (global MPI) and Millennium Development Goals (MDGs) indicators in impact evaluation SADA-Northern Ghana Village Project (MVP). We find that project had a limited on MDG yet large global MPI. assess robustness MVP MPI we this was largely driven by changes few indicators. conclude living standards, should be used with...
