DDDD Types of Echocardiography Measurement Specifications (Informative)

DDDD.1 Overview

Real-world quantities of clinical interest are exchanged in DICOM Structured Reports. These real-world quantities are identified using concept codes of three different types:

  • Standard measurements that are defined by professional organizations such as the American Society of Echocardiography (ASE), and codified by vocabulary standards such as the Logical Observation Identifiers Names and Codes (LOINC) or Systematized Nomenclature of Medicine - Clinical Terms (SNOMED-CT) standards.

  • Non-Standard measurements that are defined by a medical equipment vendor or clinical institution and codified using a private or standard Coding Scheme.

  • Adhoc measurements are those measurements that are generally acquired one time to quantify some atypical anatomy or pathology that may be observed during an exam. These measurements are not codified, but rather are described by the image itself and a label assigned at the time the measurement is taken.

This Annex discusses the requirements for identifying measurements in such a manner that they are accurately acquired and correctly interpreted by medical practitioners.
