H. Rhim et al., Per-rectal contrast material for abdominal CT: usefulness of administration with an automatic injector, ABDOM IMAG, 26(6), 2001, pp. 591-593
Adequate distention of the gastrointestinal tract is essential for the best
quality image in abdominal computed tomography. We introduce a new techniq
ue for per-rectal administration of contrast material with the use of an au
tomatic injector. With this technique, more contrast material can be insert
ed and thus adequately distend the colon, including the proximal colon.
