YYY.1 

This Annex describes the use of Preclinical Small Animal Imaging Acquisition Context.

YYY.1.1 Example of housing and anesthesia for PET-CT

This Section contains examples for use cases involving imaging of a single animal in a hybrid PET-CT system.

The basic use case involves an animal, which:

  • lives in an individually ventilated home cage with several other animals in the same cage

  • is (briefly) transported (in its home cage) with its cage mates to the imaging facility, without heating, with an appropriate lid

  • is removed from its home/transport cage for preparation for imaging, involving insertion of a tail vein cannula, performed on an electrically heated pad

  • is induced by (a) placement in an induction chamber with more concentrated volatile anesthetic, or (b) intraperitoneal injection of Ketamine mixture

  • is placed in a PET-CT compatible imaging sled/carrier/chamber for imaging (of one animal at a time), with anesthesia with Isoflurane and Oxygen as the carrier gas, and heated with an electric pad regulated by feedback from a rectal probe

  • is removed for recovery in a separate cage

The Content Tree structure (when induction is by a volatile anesthetic) would resemble:

YYY.1.2 Example of exogenous substance administration to encode tumor cell line

Only the exogenous substance information is included in this example and content describing animal handling, anesthesia information, etc. is excluded for clarity. Indeed, given the optionality of the other content, it would be possible to create an Acquisition Context SR instance that describes only the exogenous substance information and nothing else.
