API Reference

Get Ascending Aortic Diameter Values

Retrieves reference values for ascending aortic diameter based on parameter type, gender, age, and imaging technique. Provides absolute and Body Surface Area (BSA) indexed normal values of ascending aortic luminal diameter for men and women of different age categories. Data is based on measurements from phase contrast images.

This API functions as a direct lookup service for pre-calculated reference data.

Abbreviations:

  • AALD: Ascending Aortic Luminal Diameter (units: mm)
  • AALD_BSA: Ascending Aortic Luminal Diameter indexed to BSA (units: mm/m²)

Reference Data Source:

  • Eikendal AL, Bots ML, Haaring C, Saam T, van der Geest RJ, Westenberg JJ, den Ruijter HM, Hoefer IE, Leiner T. Reference values for cardiac and aortic magnetic resonance imaging in healthy young caucasian adults. PLoS ONE. 2016;11:e0164480

Important Notes:

  • HTTP Status Code: Due to Google Apps Script limitations, all responses are returned with an HTTP 200 OK status. It is crucial to inspect the JSON body for an error field to determine if the request was actually successful.
  • Parameter Selection: The parameter field determines the type of data returned. Select AALD for absolute diameter in mm, or AALD_BSA for the pre-calculated value indexed to Body Surface Area in mm/m². No height or weight input is needed.
  • Age Matching: The API matches the numeric age provided to the correct age category (age_cat) defined in the reference data (e.g., an age of 48 falls into the "45-55" category).
