Cervical carcinoma: determination of recurrent tumor extent versus radiation changes with MR imaging.

abstract：:The measured optical density of single-emulsion films depends on the film orientation. The orientation of the emulsion influences the amount of scattered light entering the detector. It is suggested that this measurement be done with the emulsion side facing the light detector. ...
