The sensitivity gain inherent to ultrahigh field magnetic resonance holds promise for high spatial resolution imaging of the heart. Here, we describe a protocol customized for functional cardiovascular magnetic resonance (CMR) at 7 Tesla using an advanced multi-channel radio-frequency coil, magnetic field shimming and a triggering concept.

The method presented here uses simultaneous positron emission tomography and magnetic resonance imaging. In the cerebral hypoxia-ischemia model, dynamic changes in diffusion and glucose metabolism occur during and after injury. The evolving and irreproducible damage in this model necessitates simultaneous acquisition if meaningful multi-modal imaging data are to be acquired.

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties. Description of the Procedures Computed Tomography (CT) scan: Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
FAQs
ECG gating aligns image acquisition with specific phases of the heartbeat. This timing reduces motion-related blurring and allows clinicians to compare cardiac structures as they contract and relax. The resulting images support assessment of chamber motion and function, which is especially important when cardiac anatomy must be interpreted together with the heart’s mechanical activity.
Cine imaging provides a time-resolved view of the beating heart rather than a single static picture. By tracking chamber motion through the cardiac cycle, it helps show how the heart moves and functions. This makes cine sequences particularly useful when the clinical question concerns chamber performance, while other sequences address tissue characteristics.
Gadolinium-based contrast is used when tissue or blood-flow information is needed beyond anatomy and motion. In cardiac MRI, it can highlight blood flow, inflammation, or scar tissue, helping distinguish areas with different myocardial characteristics. That added information supports evaluation of disease processes and myocardial viability rather than relying only on structural images.
During an examination, ECG signals synchronize the scan with the cardiac cycle, and the study can combine sequences that serve different purposes. Cine acquisitions assess movement, while contrast-enhanced sequences, when indicated, add information about flow, inflammation, or scar. This multimodal workflow produces complementary structural, functional, and tissue data in one cardiac assessment.
Clinicians may select cardiac MRI when they need to investigate cardiomyopathies, congenital heart disease, ischemia, or myocardial viability. Its value comes from addressing several clinical questions in the same examination: what the heart looks like, how it moves, and whether tissue shows abnormalities such as inflammation or scar. These findings can support diagnosis and treatment planning.
Cardiac MRI findings can contribute to follow-up as well as initial diagnosis. Repeated assessment can place structural, functional, and tissue-characterization information in the context of disease management, while research studies use the same integrated capabilities to examine cardiovascular conditions. In precision care, the combined evidence can help inform treatment planning and ongoing clinical decisions.
