Content Item Descriptions

Row 2 | Lesion Identifier is specified as a numeric text string in order to facilitate trans-coding to DICOM Attribute (0018,3105) Lesion Number and to formats for outcomes registries, such as the ACC National Cardiovascular Data Registry™. ### Note Also see TID 3105 “Lesion Identification and Properties”.
Row 3 | Finding site may span multiple segments with the proximal and distal extent specified by separate items. These may not be totally contained with the segment specified at the Vessel level.

### TID 3253 IVUS Measurements

The IVUS measurements template groups together simple distance, area and angle measurements, along with derived measurements that made during an IVUS procedure. Refer to the " ACC Clinical Expert Consensus Document on Standards for Acquisition, measurement and Reporting of Intravascular Ultrasound Studies (IVUS) "for more information.
