Instructions relating to preparation and performance of the Protocol.

See Section C.34.7.1.

One or more Items shall be included in this Sequence.

Section C.34.7.1

C.34.7.1 Instruction Sequence

This Sequence describes instructions to be performed by the scanner staff in conjunction with the Protocol. The instructions are generally limited to activites that happen inside the scan suite and might include

  • preparation of the scanner (e.g., running a particular calibration, mounting a head holder or patient grab handles on the table) ,

  • preparation of the patient (e.g., asking if they have fasted, placing padding or shielding, giving the patient water as oral contrast, turning the patient prone for the second acquisition in a virtual colonoscopy Protocol) ,

  • instructions to the patient during the imaging procedure (e.g., asking the patient to hold their breath, asking the patient to hyperventilate prior to breathold)

  • instructions to the technologist during the imaging procedure (e.g., obtain the spiral acquisition during a single breathhold, take additional images if some condition is true).

The instruction may also include timing or triggering details, for example:

  • Start the Portal Venous phase Acquisition Protocol Element when an ROI placed over the liver detects a contrast bolus at 50 HU above baseline

  • Start the Delay phase Acquisition Protocol Element three minutes after start of contrast injection

  • Start the AP Localizer Acquisition Protocol Element eight minutes after start of contrast injection and repeat the AP Localizer Acquisition Protocol Element at one minute intervals until adequate ureter opacification is observed, then proceed to the abdomen Acquisition Protocol Element

Instructions related to the initial positioning of the patient are included in the Patient Positioning Module. This Module may describe subsequent changes in position between steps of the protocol.

Equipment preparation instructions would typically be limited to phantom imaging or other calibration procedures related to the individual patient scan. Phantom Imaging and/or Calibration to be performed as general QA/qualification (i.e., not associated with the individual patient scan) shall not be described in this Module.

Activities that are associated with the protocol but which are not typically performed in the scanning room, such as the need to obtain creatinine values within 7 days before performing the Protocol, or to premedicate the patient with Benadryl 1 hour before performing the Protocol, are described in the Protocol Planning Information (0018,990F) rather than in this Module.
