Summary
Cardiac magnetic resonance (CMR) offers superior soft tissue imaging for heart conditions. New T1 mapping techniques quantitatively assess myocardial status, overcoming limitations of traditional contrast imaging for better disease detection.
Area of Science:
- Cardiovascular Imaging
- Medical Physics
- Radiology
Background:
- Cardiac magnetic resonance (CMR) excels in soft tissue differentiation, making it ideal for cardiac imaging.
- Late gadolinium enhancement (LGE) improves myocardial tissue characterization but has limitations in quantifying diffuse disease.
Purpose of the Study:
- To review the technical and clinical considerations for the practical application of pre- and post-contrast T1 mapping in CMR.
- To highlight the potential of T1 mapping to overcome limitations of existing CMR sequences.
Main Methods:
- Review of recent advances in CMR techniques, focusing on T1 mapping.
- Discussion of technical aspects and clinical utility of pre- and post-contrast T1 mapping.
Main Results:
- T1 mapping provides quantitative assessment of myocardial status.
- T1 mapping shows potential to overcome limitations of LGE for diffuse myocardial disease detection.
Conclusions:
- T1 mapping represents a significant advancement in CMR for myocardial tissue characterization.
- Practical implementation requires careful consideration of technical and clinical factors.

01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:21Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
