Myocardial Perfusion Imaging With Rb-82 PET
Myocardial perfusion imaging (MPI) is an effective technique used to study the left ventricular ejection function (LVEF), myocardial perfusion, wall motion, and wall thickening. Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are two modalities that can be …

An investigation into the limitations of myocardial perfusion imaging
Myocardial Perfusion Imaging (MPI) plays a very important role in the management of patients with suspected Coronary Artery Disease and its use has grown despite the shortcomings of the technique. Significant progress has been made in identifying the causes of these shortcomings and many solutions …

Validation of first pass magnetic resonance myocardial perfusion imaging using fractional flow reserve
Background - Magnetic Resonance Myocardial Perfusion Imaging (MRMPI) has been used for the detection of reversible myocardial ischaemia in humans since the early 1990’s. This non-invasive method of diagnosing reversible myocardial ischaemia has a number of advantages over the other more commonly …

Evaluation of the effect of breast implants on the accuracy of the CT attenuation Correction (CTAC) map for SPECT/CT myocardial perfusion imaging: a phantom study
Background: Myocardial perfusion imaging (MPI) using single photon emission computedtomography (SPECT) imaging can assess myocardial viability and perfusion. However,overlying thoracic structures, such as ribs or breast tissue lead to gamma ray attenuation. Thisattenuation does not occur equally …

Quantitative Positron Emission Tomography for Estimation of Absolute Myocardial Blood Flow
<p>Myocardial perfusion imaging (MPI) with positron emission tomography (PET) is an emerging clinical tool for diagnosis and characterization of ischemic heart disease. The increasing use of PET introduces an opportunity, as it is capable of providing quantitative images that can be analyzed with …

A subspace approach to accelerated cardiovascular magnetic resonance imaging
"Magnetic resonance imaging (MRI) is a uniquely flexible tool for imaging the heart, as it has the potential to perform a significant number of structural and functional cardiovascular assessments. However, the low imaging speed of MRI has limited its clinical application. The assessments that are …

Avaliação da redução do tempo de internação e da exposição à radiação e avaliação do impacto clínico do protocolo de Cintilografia de Perfusão Miocárdica estresseisolado comparado com o protocolo convencional estresserepouso: estudo prospectivo e meta-análise
Introduction: The Myocardial Perfusion Scintigraphy (MPS) is the noninvasive diagnostic method most accurate for the detection of obstructive Coronary Artery Disease (CAD) and for predicting outcomes in the short-term. One of the main applications of MPS is the identification of patients at risk …
