Submit Public Comments on Supplement 227: Ultrasound Elastography Structured Report, by March 18, 2022

This supplement to the DICOM Standard introduces an SR section template for Ultrasound Elastography results and a General Ultrasound Report within which it can be used.

Ultrasound elastography is used on tissues including liver, breast, prostate, and tendon. In shear wave elastography (SWE), the ultrasound system measures shear wave speed (SWS) and derives a value for elasticity (in kPa) from that. Some systems also assess viscosity (which can be correlated to inflammation) by generating a value such as shear wave dispersion slope. In strain elastography (SE), elasticity/stiffness is assessed qualitatively by comparing the compression of tissue in a target region to that of tissue in a nearby reference region.
All comments should be submitted as soon as possible but NO LATER than 11:59pm US Eastern Time on Friday, March 18, 2022.

 Who can comment? All interested persons are invited to comment. There is no cost or obligation associated with commenting and DICOM membership is not required to comment. Commenters are requested to include their contact information.

 What will happen to your comments? DICOM Working Group 6 (Base Standard) and DICOM Working Group 12 (Ultrasound) will review the comments and discuss their resolution. WG-06 is authorized by the DICOM Standard Committee to decide on the technical merits of the comments.

 Instructions for accessing the documents and submitting comments:
