Multimodal Ultrasound Biomechanical Data for Carotid Artery Thickness in Type 2 Diabetes

Xuhong Nan published a study on figshare in April 2026 analyzing multimodal ultrasound data from 65 patients with type 2 diabetes mellitus and 27 control subjects. The dataset includes measurements of carotid intima-media thickness, blood flow velocities, wall shear stress, and pulse wave velocity. The study explores subclinical vascular changes associated with diabetes.

Use Cases

• Predict carotid intima-media thickness based on biomechanical features like wall shear stress and pulse wave velocity.
• Analyze correlations between clinical variables (BMI, HbA1c) and vascular ultrasound measurements.
• Identify independent factors for subclinical vascular remodeling in type 2 diabetes using multivariable linear regression.
• Compare vascular biomechanics between diabetic patients with normal and thickened carotid intima-media and healthy controls.

Strengths

• Includes data from 92 total subjects (65 patients, 27 controls), providing a basis for group comparisons.
• Contains multiple validated ultrasound-derived biomechanical metrics, such as peak systolic velocity, wall shear stress, and pulse wave velocity.
• Statistical analysis is detailed, reporting specific correlation coefficients (e.g., ρ=0.506 for cIMT and PWV-ES) and regression results.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 17.3 KB, indicating limited scope, likely containing summary results rather than raw patient-level data.
