Abstract 胃Ⅹ線検査に造影剤として用いられる硫酸バリウム懸濁液の濃度を,簡便に,客観的に決定する目的で,歯科用アルギン酸塩印象材を用いて,コインの図柄を写しとったファントムを制作した。これを使って二種類の硫酸バリウム製剤の適正濃度(PD)を調べた結果,BARITOP PとBARICON MEALを単体,若くは混合した場合には,おおよそ,PD(W/V%)=0.75C+165(ただし,CはBARICON MEALの混合比(%))となった。また,BARICON MEALはコントラストが高く,精密検査に有利だと考えられ,BARITOP PとBARICON MEALを混合すると濃度の許容範囲が広がるため,通常の検査に都合がよいと考えられた。更に,このファントムは簡便に作成することができ,しかも,硫酸バリウム懸濁 液との親和性も良いことから,硫酸バリウム製剤やⅩ線TV装置の評価,増感紙・フィルム系の評価等にも応用できると考えられた。
Abstract Alternative A phantom copied designs of coins was created with alginate dental impression material to establish a objective, simple and easy method for deciding density of barium sulfate suspensions which are used for stomach X-ray examination as contrast media. As a result of examining proper density (PD) of two kind of barium preparations with this phantom, in case of BARITOP P and BARICON MEAL, PD were almost shown by the next equation : PD(W/V%)=0.75C+165(C meant content of BARICON MEAL (%)). As BARICON MEAL resulted in hight contrast, it was thought to be suitable for a close examination. Mixture of BARITOP P and BARICON MEAL was thought to be suited to a routine examination becouse of wide permissible level of density. This phantom would be able to apply to the test of balium preparations, X-ray TV systems, screen/film systems and so on.

Abstract 胃X線検査の被験者を増やし、検査を円滑に行う上で造影剤である硫酸バリウム懸濁液の飲みにくさが障害の一つとなっている。これを改善する目的で、懸濁液に市販の粉末清涼飲料を混入したところ、64.2%の人が通常のものよりも飲みやすいと答えた。臨床上も造影剤の付着が悪くなったり、胃の蠕動を促進する等の問題は生じず、有用であると考えられた。
Abstract Alternative Barium sulfate suspensions are disliked by many people. This is one of the obstacles to increase persons who consult doctors and to have medical examinations smoothly. We mixed soft drinks into the suspensions to improve this problem. As a result, they were popular among 64.2% people, there were not any clinical troubles that the suspensions did not stick to the mucous membrane of the stomach well, the peristalsis of the sotmach were promoted, and so on. These results suggest that the contrast media containing soft drinks is useful for the X-ray examinations of the stomach.

Abstract 胃検診の受診者を増やし、検査を円滑に行う上で、造影剤である硫酸バリウム懸濁液の飲みにくさが障害の一つとなっている。これを改善する試みとして、懸濁液に市販の粉末清涼飲料を混入し検討したところ72.1%の人から通常のものよりも飲みやすいという回答を得た。今後、臨床的な検討を加えながら、さらに創意工夫していく必要がある。
Abstract Alternative Barium sulfate suspensions are disliked to drink by many people. That is one of the obstacles to increse person who consult doctors and to have medical examinations smoothly. We mixed soft drinks into the suspensions to improve this problem. As a result they were popular among 72.1% people. We need to study about these suspensions further, adding the clinical matters.

Title Alternative Estimation of balium preparations with high density and low viscosity

Abstract In this paper we compared the balium preparations having high density and low viscosity (BP-HDLV) with those currently in use. We adopted the stomaches of pigs and the new phantom manufactured by ourselves. We especialy noted the quality of the contrast. The results indicate that BP-HDLV do not always make high contrast. The contrast is related to fluidity besides density. The fluidity of BP-HDLV should be improved. In adition, it costs much to increase content of balium. Therefore, we can not find out positive significance to use these BP-HDLV.

Abstract Utilization of radiation in medical treatment is increasing more and more ; consequently, It becomes more important to estimate exposure dose correctly. Altough there are many reports about exposue dose for patients, most of them merely describe the results of the measurements by parts of the body. Exposure dose differs with equipment, instruments, screen-firm system, contition of radiography, and so on. This paper describes the relation between skin dose and contitions of radiography, and also shows the result of measurement of "TPR" which needs to know the absorbed dose of each organ.
