V. Schar et al., DETECTION OF HYPOFRONTALITY WITH TECHNETI UM-(99M)HMPAO SPECT IN ACUTE PSYCHOSES - DIAGNOSTICS OF SCHIZOPHRENIA, Nervenheilkunde, 14(7), 1995, pp. 379-384
Studies by means of PET, Xe-133 and Tc-99m-HMPAO SPECT have revealed e
vidence of hypofrontality in patients with schizophrenia. We have asse
ssed 26 patients with acute psychoses and tried to find out whether a
schizophrenia (ICD-10: F 20) could be distinguished from differential
diagnoses of schizoid disorders (F 21) and transient acute psychotic d
isorders (F 23) by means of Tc-99m-HMPAO SPECT. Tc-99m-HMPAO SPECT doe
s not contribute to differentiation between diagnoses of schizoid and
transient acute psychotic disorders in the early stages of schizophren
ia.
