Hyperpolarized 13C urea myocardial first-pass perfusion imaging using velocity-selective excitation

open access: yesJournal of Cardiovascular Magnetic Resonance, 2017
Background A velocity-selective binomial excitation scheme for myocardial first-pass perfusion measurements with hyperpolarized 13C substrates, which preserves bolus magnetization inside the blood pool, is presented.

Myocardial perfusion abnormalities in asymptomatic type 2 diabetic patients

open access: yesJournal of the Saudi Heart Association, 2018
Objective: The prevalence of coronary artery disease (CAD) is high in patients with diabetes. Because ischemia and infarction are often silent in diabetic patients, diagnosis of CAD occurs inevitably late.

Visualization of Minute Mechanical-Excitation/Relaxation Wave-front Propagation in Myocardial Tissue

open access: yes, 2010
Unlike the case of skeletal muscle, the direction of myocardial contraction does not coincide with the direction of work necessary to eject the intraventricular blood, contributing to great complexity of the wall deformation sequence of cardiac ...

Stress myocardial perfusion imaging with multidetector CT

open access: yes, 2014
Computed tomographic (CT) coronary angiography is a well-established, noninvasive imaging modality for detection of coronary stenosis, but it has limited accuracy in demonstrating whether a coronary stenosis is hemodynamically significant.

The relative contributions of myocardial perfusion, blood volume and extracellular volume to native T1 and native T2 at rest and during adenosine stress in normal physiology

open access: yesJournal of Cardiovascular Magnetic Resonance, 2019
Background Both ischemic and non-ischemic heart disease can cause disturbances in the myocardial blood volume (MBV), myocardial perfusion and the myocardial extracellular volume fraction (ECV). Recent studies suggest that native myocardial T1 mapping can

New directions in myocardial perfusion imaging

open access: yesClinical Cardiology, 1993
AbstractIn recent years, substantial progress has been made in the field of nuclear cardiology. Pharmacologic stress perfusion imaging with intravenous administration of dipyridamole or adenosine provides comparable sensitivity and specificity values for detection of coronary artery disease (CAD) as exercise imaging and has been employed successfully ...

Multimodality Imaging of Tumour Pathophysiology and Response to Pharmacological Intervention

open access: yes, 2015
This thesis describes the need for imaging the tumour pathophysiological microenvironment in order to understand response to treatment. Specifically looking at tumour vascularisation in in vivo murine xenograft models of disease, response to treatment ...

Multislice MR first-pass myocardial perfusion imaging: impact of the receiver coil array

open access: yes, 2005
To compare a new 12-element body phased-array coil with a conventional four-element surface receiver coil array to provide increased signal-to-noise ratios (SNRs) for cardiac steady state free precession (SSFP) perfusion imaging.
