Multimodality cardiovascular imaging plays a central role in caring for patients with congenital heart disease (CHD). CHD clinicians and scientists are interested not only in cardiac morphology but also in the maladaptive ventricular responses and extracellular changes predisposing to adverse outcomes in this population. Expertise in the applications, strengths, and pitfalls of these cardiovasc...
The ability to make informed benefit-risk assessments for potentially cardiotoxic new compounds is of considerable interest and importance at the public health, drug development, and individual patient levels. Cardiac imaging approaches in the evaluation of drug-induced myocardial dysfunction will likely play an increasing role. However, the optimal choice of myocardial imaging modality and the...
Cardiovascular magnetic resonance (MR) imaging can provide three-dimensional analysis of global and regional cardiac function with great accuracy and reproducibility. Quantitative assessment of regional function with cardiac MR imaging previously was limited by long acquisition times and time-consuming analysis. The use of steady-state free precession cine MR imaging substantially improves asse...
Respiratory and cardiac motion artefacts degrade image quality in positron emission tomography (PET) imaging and may significantly affect the qualitative and quantitative evaluation of images. At worst, misguided interpretation may lead to wrong diagnosis and inadequate or unnecessary treatment. The aim of this thesis was to study the feasibility of the bioimpedancebased measurement technique f...
conclusions sm wave in tdi is prominent and significantly high in mvp syndrome. also, our study showed some degree of diastolic dysfunction in mvp patients. results seventy-five patients (48 females) at a mean age of 26.5 ± 9.4 years and 50 individuals (32 females) at a mean age of 27.1 ± 8.3 years were enrolled in the study. as the important results of our study, sm wave was much more prominen...
Three-dimensional (3D) cardiac magnetic resonance (MR) imaging has several advantages, including the easy coverage of the entire heart without misregistration, reduction of breath-holding times, and availability for postprocessing reconstruction. These advantages are associated with some techniques such as breath-hold or navigator gating and parallel imaging. However, the image quality of 3D ca...
Cardiac magnetic resonance (CMR) imaging has emerged as an important non-invasive cardiac imaging modality. A versatile technique, it has the potential for comprehensive evaluation of coronary artery disease (CAD): cardiac morphology and function, myocardial perfusion, myocardial viability, coronary artery visualisation and atherosclerotic plaque characterisation. Some of these techniques--vent...
