B. Tumors of Bones. Skiagraphy enables us to determine if a neoplasm is connected withthe compact or cancellous portion of the bone, or if it is connected withthe bone at all. Thus, the growth might be a cyst or a myoma thatclosely simulates an osteoma, an osteo-sarcoma, etc. 1 Fortschritte a. d. Geb. d.
