title: [The value of magnetic resonance tomography during radiotherapy of childhood tumors in the posterior fossa and the pineal region].
abstract: MRT is a highly sensitive method for the diagnosis of childhood tumours in the posterior fossa. Since it demonstrates tumour extent better than does CT, MRT is the method of choice for radiotherapy planning. The result of treatment can be judged morphologically and by measuring relaxation times. Changes due to treatment can be recognised more easily than by CT. A disadvantage of MRT is lack of specificity, since various processes may lead to an equal increase in T1 and T2 times.
