# CT Preventive Screening — archived pointer

This page is no longer the active owner. Its CAC/CCTA table, RPPH confirmation checklist, LDCT boundary, abdomen-CT boundary, and full-body CT avoidance rule were folded into [Cardiac Imaging & Valve Plan](#sec-ldncp-imaging) on 2026-05-10.

Preserved core rule: use CT narrowly. CAC is the low-friction coronary plaque anchor; CCTA is for symptoms, positive CAC, or direct plaque/anatomy questions; LDCT is guideline/smoking-threshold dependent; abdomen CT is symptom/structural-triggered; full-body CT screening remains a bad tradeoff.
