TID 3105 Lesion Identification and Properties

The Lesion Identification and Properties Template allows recording the identification of each lesion addressed in a procedure. The lesion identifier may be used to relate diagnostic or therapeutic actions with their target lesion (see Row 4 in TID 3010 “Log Entry Qualifiers”). This Content Item may include the initial visually estimated measurements of stenosis or TIMI flow; measured values from a quantitative measurement report may be referenced indirectly (through TID 3103 “Referenced Object”), or by quotation (TID 3109 “Measurements”). Subsequent (e.g., post-intervention) stenosis measurements may be encoded using TID 3109 “Measurements”, with the Lesion Identifier conveyed through its subsidiary TID 3010 “Log Entry Qualifiers” Template.

Content Item Descriptions

Row 1

Lesion Identifier is specified as a numeric text string in order to facilitate transcoding to DICOM Attribute (0018,3105) Lesion Number and to formats for outcomes registries, such as the ACC National Cardiovascular Data Registry™.
