目的评价计算机X线摄影系统(CR系统)在乳腺X线检查中的应用价值。材料和方法对420例1114张片的乳腺检查临床资料齐全患者进行回顾分析,另将改装前普通钼靶乳腺普查摄影53例182张作为对照组回顾分析。分别回顾分析两组钼靶乳腺摄片的应用方法、条件、体位、甲乙丙片率、废率、以及临床表现综合分析对比。结果改造后的钼靶乳腺机,明显提高乳腺摄片质量,符合人体x线物理检查条件,与目前其他医院专用乳腺摄影、CR乳腺摄片比较没有质的区别。结论具有改造成本低,临床使用价值高,经济和社会效益好,为医院节省投资2.5~10万元。
Objective To evaluate the value of computerized radiography (CR system) in mammography. MATERIALS AND METHODS: A retrospective analysis was performed on 420 cases of 1114 breast cancer with complete clinical data, and another 53 cases of general breast mammography were retrospectively analyzed. Retrospective analysis of two groups of mammography mammography application methods, conditions, body position, methyl ethyl ketone film rate, waste rate, and clinical manifestations of a comprehensive analysis and comparison. The results of the modified mammography machine, significantly improve the quality of breast radiography, in line with the physical examination of human x-ray conditions, and other hospital-specific breast photography, CR mammography comparison no qualitative difference. Conclusions It has the advantages of low transformation costs, high clinical value, good economic and social benefits, saving the hospital 2.5 to 100,000 yuan.
