Rationale and Objectives. The authors set out to pro- vide 1st-year re
sidents with basic knowledge to make conferences more useful, to make
their knowledge more uniform, and to assess their competency to begin
night call. Materials and Methods. Faculty taught three afternoon sess
ions a week in subspecialty areas of radiology, including physics, dur
ing the 1st 6 months of residency. Material selected was believed to b
e essential for the understanding of that subspecialty's didactic lect
ure series. Emphasis was also placed on diagnoses residents would be e
xpected to make once they began taking night call. Material was presen
ted through lectures, images, and unknown cases. An examination was ad
ministered at the end of the course. Residents were allowed to begin n
ight can only after completing the course and passing the final examin
ation.Results. All Ist-year residents completed the course and passed
the examination. Their scores ranged from 70% to 83.3%. Conclusion. Re
sidents liked the course and reported feeling ready to begin call. Fac
ulty reported the residents who completed the course were more knowled
geable prior to formal rotations than residents from previous years wh
o had not taken the course.
