Radiographic visualization of cervix and vagina during intracavitary radium therapy.

Dry barium-impregnated vaginal packing used in several hundred intracavitary uterine radium insertions has allowed excellent radiographic visualization of the relationship of the radium implant to both the cervical and vaginal walls.

Sacrococcygeal dermoids and teratomas: historical review.
