Content Item Descriptions

CAD Algorithm Identification If more than one analysis algorithm has the same “Analysis Performed” code value (e.g., CID 6043) then the “CAD Algorithm Identification” shall unambiguously distinguish between algorithms.
Rows 3 - 6 Mammography CAD SR: When this template is invoked for the Mammography CAD SR, the Image Library is mandatory, and a total of at least two instances of row 4 or row 6 shall be present. Chest CAD SR: When this template is invoked for the Chest CAD SR, the Image Library is optional, thus any combination of rows 3, 4, 5 and 6 may be present. Colon CAD SR: When this template is invoked for the Colon CAD SR, the Image Library does not exist, thus rows 3, 5 and/or 6 may be present and row 4 shall not be present.
Rows 7 - 8 Mammography CAD SR: When this template is invoked for the Mammography CAD SR, the Image Library is mandatory, thus only row 8 shall be present. Chest CAD SR: When this template is invoked for the Chest CAD SR, the Image Library is optional, thus row 7 or 8 may be present. Colon CAD SR: When this template is invoked for the Colon CAD SR, the Image Library does not exist, thus only row 7 may be present.
