Image Registration in Myocardial Perfusion MRI [PDF]

open access: yes2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005
In clinical first-pass myocardial perfusion studies, physiological and patient motions are inevitable. Such motions impair the sensitivity and reliability in assessing myocardial perfusion abnormalities. The current study aims to correct the misregistration of myocardium during first-pass perfusion imaging by using a normalized mutual information ...

Non-invasive imaging in detecting myocardial viability: Myocardial function versus perfusion

open access: yesInternational Journal of Cardiology: Heart & Vasculature, 2014
Coronary artery disease (CAD) is the most prevalent and single most common cause of morbidity and mortality [1] with the resulting left ventricular (LV) dysfunction an important complication.

Beam hardening artifact reduction using dual energy computed tomography: implications for myocardial perfusion studies [PDF]

open access: yes, 2015
Background: Myocardial perfusion computed tomography (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly observed at the left ...

Spatio-Temporal Modelling of Perfusion Cardiovascular MRI [PDF]

open access: yes, 2010
Myocardial perfusion MRI provides valuable insight into how coronary artery and microvascular diseases affect myocardial tissue. Stenosis in a coronary vessel leads to reduced maximum blood flow (MBF), but collaterals may secure the blood supply of the ...

Diagnostic accuracy of myocardial perfusion imaging with czt technology. Systemic review and meta-analysis of comparison with invasive coronary angiography [PDF]

open access: yes, 2017
OBJECTIVES: This study sought to summarize the evidence on stress myocardial perfusion imaging (MPI) using cadmium-zinc-telluride (CZT) technology for the diagnosis of obstructive coronary artery disease (CAD). The CZT cameras are newly introduced, and

Stable coronary syndromes: pathophysiology, diagnostic advances and therapeutic need [PDF]

open access: yes, 2018
The diagnostic management of patients with angina pectoris typically centres on the detection of obstructive epicardial CAD, which aligns with evidence-based treatment options that include medical therapy and myocardial revascularisation.

Dynamic CT myocardial perfusion imaging [PDF]

open access: yesEuropean Journal of Radiology, 2016
Non-invasive cardiac imaging has rapidly evolved during the last decade due to advancements in CT based technologies. Coronary CT angiography has been shown to reliably assess coronary anatomy and detect high risk coronary artery disease. However, this technique is limited to anatomical assessment, thus non-invasive techniques for functional assessment

Appropriateness of referrals for single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) in a developing community: A comparison between 2005 and 2009 versions of ACCF/ASNC appropriateness criteria [PDF]

open access: yes, 2011
Appropriateness of referrals for myocardial perfusion imaging (MPI) in developing countries has not been extensively studied. Our study was conducted to describe the ordering practices of physicians and appropriateness of MPI referrals in Iran.
