The purpose of this study was to compare the changes of regional cerebral blood flow (rCBF) in autistic and non-autistic controls, and to determine the relationship between rCBF on Tc-99m-hexamethylpropylene amine oxime (HMPAO) brain SPECT and the scores of the Ritvo-Freeman Real Life Rating Scale (RLRS), IQ levels, and age of autistic children. Eighteen autistic children (four girls, 14 boys: mean age: 6.13 +/- 1.99 years) and I I non-autistic controls (five girls, six boys, mean age: 6.5 +/- 3.39 years) were examined using Tc-99m-HMPAO brain SPECT. All the children satisfying DSM-IV criteria for autistic disorder were taken into evaluation, and scored by the Ritvo-Freeman RLRS, IQ levels of these children were determined by Goodenough IQ test. Six cortical regions of interest (ROIs; frontal (F), parietal (P), frontotemporal (FT), temporal (T), temporo-occipital (TO), and occipital (0)) were obtained on transaxial slices for count data acquisition. The ratio of average counts in each ROI to whole-slice Counts for the autistic children was correlated with the scores of Ritvo-Freeman RLRS. Hypoperfusion in rCBF in autistic children compared with the control group were identified in bilateral F. FT, T, and TO regions. We found no relationship between rCBF on Tc-99m-HMPAO brain SPECT and the scores of the Ritvo-Freeman RLRS. There was a relationship between bilateral F regions perfusion on Tc-99m-HMPAO brain SPECT and the age of autistic children. There was also a negative correlation between IQ levels and the scores of sensory responses, social relationship to people, and sensory-motor responses. Our results suggest that Tc-99m-HMPAO brain SPECT is helpful to locate the perfusion abnormalities but no correlation is found between rCBF on Tc-99m-HMPAO brain SPECT and the scores of Ritvo-Freeman RLRS.

Methods: The group consisted of 23 patients with CRF (13 female, 10 males mean age: 40 +/- 13 yr) and 14 healthy control subjects (mean age: 40 +/- 13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation, After intravenous administration of Tc-99m pertechnetate, first. perfusion images at 2 seconds per frame were acquired for I minute, then dynamic images at 1 minute per frame were acquired for 45 minutes, At 30 minutes after injection, 10 ml lemon juice was given for 15 minutes as a gustatory stimulus. We obtained time-activity curves derived from regions of interest centered over the four major salivary glands. The following functional indices were calculated for each gland: the time of maximum radioactivity (T-max) for the prestimulated period, the time of minimum radioactivity (T-min), as an indicator of velocity of secretion after stimulation, and the Lem E-5% value as an indicator of the secretion function. Results: When the patients with CRF undergoing hemodialysis were compared to the controls, there were statistically significant differences in T-max, T-min and Lem E5% values for bilateral parotid glands, and Train values for bilateral submandibular glands (p < 0.05), there were no statistically significant differences in Tmax and Lem E5% values for bilateral submandibular glands. There were also significant differences in T-max and Lem E5% values for bilateral parotid glands between mild oral problems and severe oral problems in patients with CRF (undergoing hemodialysis). Conclusion: In this study, prolonged T-max and T-min values, and decreased Lem E5% values for parotid glands and prolonged T-min values for submandibular glands on salivary scintigraphy pointed out decreased parenchymatous and excretory function in patients with CRF undergoing hemodialysis.Öğe Scintigraphic assessment of pre- and postop nasal mucociliary clearence in patients (Pts.) with nasal septal deviation using Tc-99m MAA(Springer Verlag, 1999) Yüksel, M; Çermik, TF; Özel, ES; Koten, M; Üstün, F; Karasalihoglu, A; Berkarda, S[Abstract Not Available]Öğe Secretion of radioactivity in breast milk after Tc-99m DTPA aerosol and Tc-99m MAA lung imaging(Lippincott Williams & Wilkins, 2001) Kaya, M; Üstün, F; Gültekin, A; Çermik, TF; Yüksel, MA; Yigitbasi, ÖM[Abstract Not Available]
