Cardiovascular Magnetic Resonance [PDF]

Circulation, 2001
Cardiovascular magnetic resonance (CMR) creates images from atomic nuclei with uneven spin using radiowaves in the presence of a magnetic field. Full details of the physical principles can be found elsewhere.1 For clinical purposes, MR is performed using hydrogen-1, which is abundant in water and fat. Radiofrequency waves excite the area of interest to

Cardiovascular magnetic resonance imaging [PDF]

Clinical Cardiology, 2007
Spin-echo imaging is commonly used for assessment of cardiac and great vessel anatomy. With classic spin-echo imaging, rapidly moving blood appears dark. At current field strengths (1.5 and 3.0 tesla), cardiovascular magnetic resonance (CMR) imaging is considered safe for bioprosthetic and mechanical heart valves.

Post-mortem study of the association between cardiac iron and fibrosis in transfusion dependent anaemia

Journal of Cardiovascular Magnetic Resonance, 2017
Background Heart failure related to cardiac siderosis remains a major cause of death in transfusion dependent anaemias. Replacement fibrosis has been reported as causative of heart failure in siderotic cardiomyopathy in historical reports, but these ...

An in-vivo comparison of stimulated-echo and motion compensated spin-echo sequences for 3 T diffusion tensor cardiovascular magnetic resonance at multiple cardiac phases

Journal of Cardiovascular Magnetic Resonance, 2018
Background Stimulated-echo (STEAM) and, more recently, motion-compensated spin-echo (M2-SE) techniques have been used for in-vivo diffusion tensor cardiovascular magnetic resonance (DT-CMR) assessment of cardiac microstructure.

Dobutamine Cardiovascular Magnetic Resonance

Imaging Decisions MRI, 2003
Dobutamine stress cardiovascular magnetic resonance (CMR) is a new diagnostic tool for the noninvasive detection of coronary artery disease. With technological advances, CMR has evolved to become an adequate alternative to standard cardiac stress tests such as ECG exercise stress testing, stress echocardiography, and perfusion scintigraphy.

Cardiac stress T1-mapping response and extracellular volume stability of MOLLI-based T1-mapping methods

Scientific Reports, 2021
Stress and rest T1-mapping may assess for myocardial ischemia and extracellular volume (ECV). However, the stress T1 response is method-dependent, and underestimation may lead to misdiagnosis.
