The Society for Cardiovascular Magnetic Resonance Registry at 150,000

Area of Science:

• Cardiology
• Medical Imaging
• Data Science

Background:

• Cardiovascular magnetic resonance (CMR) is vital for assessing cardiovascular conditions.
• The Society for Cardiovascular Magnetic Resonance (SCMR) Registry collects real-world clinical data for research, quality improvement, and machine learning.
• The Registry utilizes a secure, cloud-based infrastructure for data and imaging storage.

Purpose of the Study:

• To summarize the current status and contents of the SCMR Registry.
• To report on the registry's data security, submission, and access processes.
• To highlight the registry's growth and utility at 150,000 exams.

Main Methods:

• Data were compiled from 154,458 CMR scans across 20 US sites.
• Registry contents were interrogated to summarize key data points.
• Processes for data security, submission, and research access were outlined.

Main Results:

• The registry holds 154,458 CMR scans (299,622,066 images, ~100 TB).
• Patient demographics include average age 58, 44% female, 72% Caucasian, with an 8% mortality rate.
• Common indications include cardiomyopathy (27%); macrocyclic gadolinium agents used in 89% post-2015; LGE in 66% of tagged scans.
• Increased mortality observed with LVEF <35%, wall motion abnormalities, stress perfusion defects, and infarct LGE.

Conclusions:

• The SCMR Registry promotes evidence-based CMR use through secure data sharing for research, education, and quality control.
• It quantifies practice changes and supports large-scale, real-world multicenter observational studies.
• The registry enhances the prognostic utility of CMR in clinical practice.
