Objective symmetry detector method for gammaencephalography. II. Normal range.
A standardized clinical examination procedure of a previously described symmetry detector method for gammaencephalography is presented and the results obtained from a reference group of subjects without known neurologic disorders are reported. The 99TcmO4 distribution in the skull was investigated by 208 evaluation parameters obtained from measurements of 24 subregions of the skull from 48 symmetrical positions. Mean values and associated inter-individual and intra-individual standard deviations are given. Different sources of variation are discussed in relation to the results obtained. The method enables the 99TcmO4 distribution in the skull to be objectively classified as normal or abnormal.
