Mh. Schreiber et al., TECHNICAL ADEQUACY OF FLUOROSCOPIC SPOT FILMS OF THE GASTROINTESTINAL-TRACT - COMPARISON OF RESIDENTS AND TECHNOLOGISTS, American journal of roentgenology, 166(4), 1996, pp. 795-797
OBJECTIVE. We compared images obtained during gastrointestinal fluoros
copy by specially trained and experienced technologists with those obt
ained by radiology residents to determine if the quality of images was
similar between the two groups. MATERIALS AND METHODS. Three senior r
adiologists examined the fluoroscopic spot films of 80 patients who we
re divided evenly into four groups: barium enemas performed by technol
ogists, barium enemas performed by residents, gastrointestinal series
performed by technologists, and gastrointestinal series performed by r
esidents, The senior radiologists graded adequacy of visualization of
the esophagus, stomach, duodenum, and all parts of the colon, A grade
of 1 was given for poor films, 2 for adequate films, and 3 for good fi
lms. They did not know who performed each study. RESULTS. For barium e
nemas, the residents' mean score was slightly higher than that of the
technologists (13.5 compared with 12.9), For gastrointestinal series,
residents' mean score was again slightly higher (20.5 compared with 19
.7). In neither case did the difference reach statistical significance
. CONCLUSION. Fluoroscopic films obtained by residents and by speciall
y trained and experienced technologists for barium enemas or gastroint
estinal series were statistically indistinguishable.
