4D Flow MRI Data for Diastolic Assessment in Overweight Adults

Comprising de-identified 4D flow cardiovascular magnetic resonance (CMR) data from a study on overweight adults with and without type 2 diabetes mellitus. It includes representative 4D flow MRI data and derived measurements for reproducing analyses related to left ventricular diastolic flow and E/A vorticity ratio assessment. The dataset was authored by Park, Sungho and is hosted by Harvard Dataverse.

Use Cases

• Analyze 4D flow MRI data to assess left ventricular diastolic flow patterns in overweight adults.
• Calculate and compare the E/A vorticity ratio between cohorts with and without type 2 diabetes mellitus.
• Reproduce key analyses from the published study on comprehensive CMR evaluation using the provided derived measurements.

Strengths

• Data is de-identified, facilitating research use.
• Dataset is associated with a peer-reviewed publication in Cardiovascular Diabetology (2025).
• Includes derived measurements specifically for E/A vorticity ratio assessment.

Limitations

• The specific sample size (number of subjects or rows) is unknown.
• The available variables and file formats are not specified, limiting immediate usability assessment.
• Data represents a specific subset focused on overweight adults, which may limit generalizability to other populations.
