[Exploration with CT before and after cranial irradiation in ALL and NHL (author's transl)]

In 72 children (44 boys and 28 girls, 1 to 14 years old) with acute lymphocytic leukemia (ALL) or malignant non-Hodgkin lymphomas (NHL), computed tomography was used for exploration of the brain before and up to 8 years after the radiation therapy. Thus, 67 normal and 25 pathological findings resulted; nevertheless, in 10 of the children examined prior to radiation therapy, computed tomography had already shown pathological findings.
