[en] The sensitivity of radionuclide imaging and computed tomography (CT) was evaluated in 25 patients for early detection of viral meningoencephalitis. Diagnosis was based on clinical evidence, cerebrospinal fluid (CSF) studies, electroencephalography (EEG) and radionuclide imaging. Computed tomography with contrast enhancement was performed within four days after onset of neurological signs or symptoms in 23 patients; no significant findings such as low-absorption abnormalities, mass effect or abnormal enhancement were seen. Radionuclide imaging demonstrated a sensitivity of 90% in the detection of viral meningoencephalitis; the temporal lobe was most commonly involved in patients with herpes encephalitis. Radionuclide imaging should be considered as the first diagnostic procedure in suspected early viral meningoencephalitis

[en] The moving table technique for total body irradiation (MTT TBI) has some advantages in regard to dose homogeneity, patient positioning and comfort. However, divergence of the radiation field coupled with patient motion necessitates corresponding motion of the shielding blocks and verification film so that penumbra is minimized. MTT TBI system is presented, together with dose calculations, incorporating moving trays for shields and film to ensure dose delivery with minimal penumbra of the blocked field. (author.)
