The quality correction in the air kerma dosimetry for Ir-192 using farmer type ionization chambers calibrated by Co-60 quality is required. In this study we determined quality factor (kappa u) of two ionization chambers of PTW-N30001 and N23333 for Ir-192 source using dosimetric method. The quality factors for energy spectrum of microSelectron were determined as kappa u=1.016 and 1.017 for PTW-N30001 and N23333 ionization chambers respectively. We applied quality factors in air kerma dosimetry for microSelectron source and compared with reference values. As a results we found that the differences between reference air kerma rate and measured it with and without quality correction were about -0.5% and -2.0% respectively.

We report a case of acute transient encephalopathy with mental alteration, myoclonic jerks, and periodic triphasic wave electroencephalographic patterns caused by a therapeutic dose of baclofen. The clinical and electroencephalo-graphic abnormalities improved to a normal range shortly after baclofen was discontinued. We discuss the pathogenesis and review the literature about baclofen-induced encephalopathies.

PURPOSE: The purpose of this study was to develop PC-based perfusion software using Microsoft Windows. This software was developed to reformat perfusion maps including CBV (Cerebral Blood Volume), MTT (Mean Transit Time), and CBF (Cerebral Blood Flow) maps and to analyze perfusion quantitatively. MATERIALS AND METHODS: Windows-based perfusion software was developed using IDL (Interactive Data Language) as the development tool. The perfusion software was written to load the source image from dynamic first-pass cerebral perfusion CT and to reformat perfusion maps. Mean perfusion values in gray matter and white matter were calculated and compared to previously calculated data reported in literature. RESULTS: This software reformatted first pass perfusion maps in a user-friendly PC and calculated CBV, MTT, and CBF values. The values were within the normal range of the mean values when compared to previous studies. CONCLUSION: CT perfusion maps and perfusion values can be obtained by using the newly developed PC-based perfusion software. Further study is needed to achieve more precise values. However, we believe that in the future, this program may be used in various clinical settings.

In order to observe the influence of visual display terminal (VDT) work on accommodative function, we measured accommodative power, accommodative constriction time and accommodative response / accommodative stimulus ratio (Ar / As) by infrared optometer on 15 normal subjects who were not exposed to VDT work before. VDT task was programed to search a specified Korean alphabet letter among randomized letters for 90 minutes. After VDT task, accommodative constriction time was prolonged, near point extended and accommodative power decreased in all subjects (p<0.05, by paired t-test). After resting for 30 minutes, constriction time, near point and accommodative power had a tendency to return to the previous normal value. Accommodative response / accommodative stimulus ratio (Ar / As) was decreased according to the duration of VDT work but no statistical difference was found between before and after VDT work. From this study, it is suggested that the function of accommodation seems to be affected by VDT work.
