Download or read book Free Breathing Non ECG T1 Mapping in the Heart written by Jaime Shaw and published by . This book was released on 2017 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular diseases are the leading cause of death in the United States, translating to a high cost burden on the healthcare system. Noninvasive imaging can play a significant role in the diagnosis and triaging of cardiovascular diseases. Cardiac MRI is a noninvasive imaging technique becoming more prevalent due to its advantage of providing excellent soft-tissue contrast and high spatial resolution without the use of ionizing radiation; however, major challenges exist including respiratory and cardiac motion. One emerging application of cardiac MRI is myocardial tissue characterization using quantitative mapping techniques. Current mapping techniques rely on electrocardiogram (ECG)-gating which assumes normal sinus rhythm, as well as breath-holds or respiratory monitoring which preclude some patients from scans or prolong scan time. Quantification of spin-lattice relaxation times (or T1 mapping) of the myocardium has been shown to enable detection of diffuse myocardial fibrosis, a key feature in the progression of many cardiac diseases. The main focus of this dissertation is to remove the limitations of ECGs and respiratory monitoring from cardiac MRI to enable free-breathing, non-ECG T1 mapping. The first objective of this dissertation was to develop a two-dimensional, free-breathing, non-ECG, continuous T1 mapping technique and validate it in imaging phantoms using a gold-standard technique. We compare the T1 and extracellular volume (ECV) values to a conventional breath-hold, ECG-gated, T1 mapping technique in healthy subjects. The repeatability and accuracy of the technique were assessed for different length scans. The second objective was to demonstrate the feasibility of quantifying T1 values throughout the cardiac cycle and to assess cardiac function simultaneously with a method free of ECG and prospective respiratory monitoring. The third objective of this dissertation was to develop a three-dimensional free-breathing, non-ECG T1 mapping technique capable of providing T1 and ECV maps with full coverage of the left ventricle. This dissertation lays the groundwork for quantitative cardiac MRI with no reliance on prospective respiratory monitoring or ECGs. The removal of these limitations makes cardiac MRI accessible to all types of patients and provides a comfortable scan environment with no breath-holding. This dissertation represents a move toward a "push-button" cardiac MRI paradigm, wherein one scan with minimal setup can provide information comparable to a complex standard-of-care cardiac MRI scan.

Download or read book Advanced Quantitative Indexes in Cardiovascular Magnetic Resonance Imaging written by Xiaoyue Zhou and published by Frontiers Media SA. This book was released on 2024-08-28 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decades, advanced quantitative indexes obtained by cardiovascular magnetic resonance imaging (CMRI), such as myocardial strain, myocardial T1/ECV/T2/T2* relaxation value, myocardial blood flow quantification index and hemodynamics indexes, have been proposed as an alternative for non-invasive quantitative evaluation in various cardiovascular diseases. Those quantitative indexes have been proven to be more sensitive in assessing the early change of myocardial tissue, ventricular function, or hemodynamics, compared to the conventional qualitative methods. However, there are many challenges in the accurate measurement of those indexes as well as the evaluation of their clinical significance in the diagnosis and prognosis of a certain disease. Besides, quality control and standardization of those indexes become crucial when promoting them into clinical practice. This Research Topic will offer comprehensive reviews and original research articles of the newly emerged quantitative CMRI methods and the clinical insights of the diagnostic and prognostic value of those advanced CMRI indexes. CMRI techniques such as myocardial strain analysis, quantitative myocardial tissue mapping, 2-dimensional / 4-dimensional flow quantification and quantitative perfusion will be of our interest. The aim of this Research Topic will be to highlight the promising technical improvements in the accurate measurement of the CMRI indexes, and/or the added value of those indexes in disease diagnosis and prognosis. Meanwhile, quality control and standardization of the advanced CMRI indexes in multi-centre / multi-vendor research projects will be discussed.

Download or read book MRI of the Lung written by Hans-Ulrich Kauczor and published by Springer Science & Business Media. This book was released on 2008-11-12 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade significant developments have been achieved in the field of magnetic resonance imaging (MRI), enabling MRI to enter the clinical arena of chest imaging. Standard protocols can now be implemented on up-to-date scanners, allowing MRI to be used as a first-line imaging modality for various lung diseases, including cystic fibrosis, pulmonary hypertension and even lung cancer. The diagnostic benefits stem from the ability of MRI to visualize changes in lung structure while simultaneously imaging different aspects of lung function, such as perfusion, respiratory motion, ventilation and gas exchange. On this basis, novel quantitative surrogates for lung function can be obtained. This book provides a comprehensive overview of how to use MRI for imaging of lung disease. Special emphasis is placed on benign diseases requiring regular monitoring, given that it is patients with these diseases who derive the greatest benefit from the avoidance of ionizing radiation.

Download or read book MRI from Picture to Proton written by Donald W. McRobbie and published by Cambridge University Press. This book was released on 2017-04-13 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: MR is a powerful modality. At its most advanced, it can be used not just to image anatomy and pathology, but to investigate organ function, to probe in vivo chemistry, and even to visualise the brain thinking. However, clinicians, technologists and scientists struggle with the study of the subject. The result is sometimes an obscurity of understanding, or a dilution of scientific truth, resulting in misconceptions. This is why MRI from Picture to Proton has achieved its reputation for practical clarity. MR is introduced as a tool, with coverage starting from the images, equipment and scanning protocols and traced back towards the underlying physics theory. With new content on quantitative MRI, MR safety, multi-band excitation, Dixon imaging, MR elastography and advanced pulse sequences, and with additional supportive materials available on the book's website, this new edition is completely revised and updated to reflect the best use of modern MR technology.
