Provides LMS parameters to calculate z-scores for distensibility of the ascending aorta (AA) relative to age in children.

The underlying data and methodology are from the reference: Voges I, Jerosch-Herold M, Hedderich J, Pardun E, Hart C, Gabbert DD, Hansen JH, Petko C, Kramer HH, Rickers C. Normal values of aortic dimensions, distensibility, and pulse wave velocity in children and young adults: a cross-sectional study. J Cardiovasc Magn Reson. 2012;14:77

Measurement Context: Distensibility was calculated based on measurements of the aortic area at systole and diastole on cross-sectional cine gradient echo images obtained perpendicular to the axis of the ascending thoracic aorta.

LMS Parameters:

• L (Lambda): Skewness of the distribution.
• M (Mu): Median value.
• S (Sigma): Coefficient of variation.

Important Notes:

• HTTP Status Code: All responses have an HTTP 200 OK status. You must check the JSON body for an error field to determine if the request was successful.
• Age: The age parameter should be the patient's age in whole years. For infants under 1 year old, use age=0.
