Summary
Tailored cardiac magnetic resonance (CMR) protocols significantly reduce scan times by over 30% while maintaining diagnostic accuracy. These question-driven approaches improve efficiency for cardiomyopathy and ischemic heart disease evaluations.
Area of Science:
- Cardiovascular Imaging
- Medical Technology
- Diagnostic Accuracy
Background:
- Long scanning times limit the clinical adoption of cardiac magnetic resonance (CMR).
- Standardized shortened protocols risk reduced diagnostic information.
- Tailored protocols are needed to balance efficiency and comprehensive assessment.
Purpose of the Study:
- To develop and evaluate question-driven CMR and stress-CMR protocols.
- To assess the effectiveness of tailored protocols in reducing scan time.
- To determine if diagnostic performance is maintained compared to standard protocols.
Main Methods:
- Developed tailored CMR and stress-CMR protocols with advanced tissue characterization.
- Included standard cines, LGE, T1-mapping, ECV, and optional modules based on clinical questions.
- Optimized workflow to achieve time targets of <30 min for CMR and <35 min for stress-CMR.
Main Results:
- Average scan duration decreased by over 30% (CMR: 42±8 to 28±6 min; stress-CMR: 50±10 to 34±6 min).
- CMR was impactful in ~60% of cases, and advanced tissue characterization in >45% of cases.
- Image quality and diagnostic impact were similar to standard protocols; no additional staff were required.
Conclusions:
- Tailored CMR and stress-CMR protocols are accurate and time-effective for cardiomyopathies and ischemic heart disease.
- These protocols maintain diagnostic performance while significantly reducing scan duration.
- Question-driven, tailored imaging enhances clinical utility and efficiency in cardiac MRI.

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...

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,...

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...
