Magnetic resonance imaging (MRI) along with computed tomography (CT) is considered the gold standard for the quantitative measuring of adipose tissue in humans. The aim of this study is to evaluate usefulness of MRI for the measurement of abdominaladipose tissue in dogs compared with CT and to establish an optimal method for evaluation of abdominal adipose tissue using MRI in dogs. MR scans with T1- weighted breath hold RSSG (radiofrequency spoiled-steady gradient rewound acquisition) and helical CT scans were performed from the diaphragm to the sacroiliac joint in 19 dogs. The MR images were analyzed by manual and semiautomatic methods for the measurement of abdominal adipose tissue. And abdominal adipose tissue was determined by using the attenuation range from -141 to -93 Hounsfield unit in the CT images. The mean total adipose tissue volumes of the entire abdomen measured by MRI and CT were no significant difference, which were strongly correlated (r = 0.958, p < 0.01). And there was good agreement between the total abdominal adipose tissue area determined by semiautomatic single-slice method at L2-3 level and the whole abdominal adipose tissue volume measured by manual multi-slice method using MRI (r = 0.963, p < 0.01). MRI acquisition technique and imaging analytic method for measuring abdominal adipose tissue used in this study enable to make a fast and reliable abdominal adipose tissue quantitative measurement. In conclusion, MRI could be a good alternative to CT for the measurement of abdominal adipose tissue in dogs. ______ Keywords: abdominal adipose tissue, measurement, magnetic resonance imaging, dogsCONTENTS I.

[영문]Though the development of medical device contained embedded software implemented the various functions has been recently increased, the evaluation for these does not exist. Moreover embedded software for medical device has controlled medical devices considered as high risk product because of close relation to life of human being, the specific management for quality is positively necessary. Therefore I intended to develop a third party evaluation criteria and procedure to guarantee safety and reliability for medical embedded software.Evaluation items of medical embedded software were selected based on the international standard for software product quality ISO/IEC 9126 series. The questionnaire survey of medical embedded software developer was conducted to determine the weight of each evaluation items for more objective evaluation and then AHP theory was applied to the questionnaire results. And the detailed evaluation procedure was presented including the object of evaluation, the requirements of laboratory and evaluator, the documentation list necessary to submit and the criteria, based on the international standard for software product evaluation ISO/IEC 14598 series.Where the evaluation of electrical medical device, the evaluation criteria and procedure proposed in this paper is applied together with the existing test for hardware, they are expected to contribute to the safety and reliability of medical device.ope
