Why DSA test is done?
Why do you need a Digital Subtraction Angiography (DSA)? This examination technique is commonly used to diagnose a variety of blood vessel diseases. You may need to undergo DSA to diagnose obstructive vascular diseases that are caused by blocks or narrowing in the lumen (inner surface) of arteries and veins.

What is the purpose of the DSA IR form?
DSA Forms or DSA Publications webpages. PURPOSE: This Interpretation of Regulation (IR) provides clarification of specific Code requirements relating to construction changes that must be submitted to DSA and defines the construction change document process. DEFINITIONS: The following definitions apply to terms used in this document:
How to submit a construction change document DSA 140?
DSA 140: Application for Approval of Construction Change Document -CCD Category A/B depicted in Appendix A of this IR and available on the DSA forms page. Submittal process requirements are defined in Section 2 of this IR and must be followed.
When do CCD’s need to be submitted to DSA?
CCD Category A. • A CCD Category A is required to be submitted to and approved by DSA prior to commencement of the affected work. • A CCD Category A must be submitted to DSA using form
Do you need to submit change orders to DSA?
Change Orders are not required to be submitted to DSA. The CCD process replaces the need to submit Change Orders (except as noted in Section 7). Changes to the construction cost are reported to DSA using form DSA 168: Statement of Final Actual Project Cost at the conclusion of the project.
