    Brain Abscess Drainage by Use of Mr Fluoroscopic Guidance
    (Amer Soc Neuroradiology, 2005) Ünal, O; Sakarya, ME; Kiymaz, N; Etlik, O; Kayan, M; Kati, I; Harman, M
    We describe herein the use of MR fluoroscopic guidance in the drainage of abscess cavities. We percutaneously drained 12 brain abscesses in 11 patients. A 0.3T open MR imaging system was used. Sixteen drainages were performed in 12 abscesses. Repeat drainage was needed in three recurrences and one residual lesion. No serious complications were seen. MR fluoroscopy-guided percutaneous brain abscess drainage in an open MR imaging system is feasible.

    Cranial Mri Findings in Children With Protein Energy Malnutrition
    (Taylor & Francis Ltd, 2005) Odabas, D; Çaksen, H; Sar, F; Ünal, O; Tuncer, O; Atas, B; Yilmaz, C
    In this study, cranial magnetic resonance imaging (MRI) findings were investigated in children with moderate and severe protein energy malnutrition (PEM) to determine cerebral abnormalities in malnutrition in childhood. A total of 20 children aged 3 months to 36 months were included in the study. Thirteen (65%) children had severe malnutrition and seven (35%) children had moderate malnutrition. Fifteen (75%) children had abnormal MRI findings: all of them had cerebral atrophy, and 10 (75%) children had cerebral atrophy plus ventricular dilatation. None of the children had abnormality in the brain stem or cerebellum. The authors did not find statistically significant differences between the groups when comparing the MRI findings for degree of malnutrition, head circumference, iron deficiency anemia, and serum albumin levels. In conclusion, the findings showed that most (75%) children with moderate/severe PEM had abnormal MRI findings. Therefore, it is suggested that children with PEM should be evaluated for cerebral atrophy.
