SECTION B: Contrast CT Scanning Protocol (1 non contrast scan and 1 contrast scan) START OF SECTION B Scan 1: n contrast CT at full inspira on (TLC) Is actual DLP more than 125 mgy*cm? to Scan 2 Do not perform Scan 2. Skip to sec on C. Scan 2: Contrast CT at relaxed exhala on (FRC) A er scan length is set from topogram, FRC es mated DLP: Is es mated DLP more than 300 mgy*cm? Perform scan Add FRC Es mated DLP to TLC Actual DLP Is sum of the two DLP more than 425 mgy*cm? Perform scan Do not perform Scan 2. Skip to sec on C. Quality of performed scans: Followed breathing instruc ons for all performed scans Mo on ar fact on any performed scan Inclusion of whole lung on all performed scans Page 3 of 6
Alarm findings (e.g., large mass, large effusion): If yes, describe: Unexpected event:, specify: Fain ng episode Allergic reac on suspected END OF SCANNING. END OF STUDY. DO NOT COMPLETE SECTION C. SECTION C: n Contrast CT Scanning Protocol (3 non contrast scans) START OF SECTION C *Cau on: Do NOT complete this sec on if par cipant performed ALL of Sec on B* Was the non contrast CT at full inspira on (TLC) already performed during Contrast Protocol? to Scan 1 Is actual DLP more than 200 mgy*cm?
