Mammography has been digitized in all cases at our hospital. Digital mammography (MMG) of our hospital and its diagnostic accuracy were described in this report. Fuji Computed Radiography (FCR; Fuji Medical Systems, Tokyo, Japan) imaging plate was used and imaging data were processed with FCR 7000 or FCR 9000. Each image was output to a single hard copy. Sampling pitches for reading and output were 0.1 mm. The rate of breast cancer diagnosis by digital MMG was 67%, 95%, 94%, and 100% for unpalpable tumor, tumor less than phi 2 cm, tumor of phi 2 to 5 cm, and tumor greater than phi 5 cm, respectively, being 94% overall. Digital MMG enables us to establish goal-oriented image-processing conditions. The use of digital MMG, which provides an excellent diagnostic rate similar to that of screen-film MMG, is expected to became wide-spread in the near future.
我院所有病例的乳腺钼靶检查均已数字化。本报告描述了我院的数字乳腺钼靶（MMG）及其诊断准确性。使用富士计算机放射成像（FCR；富士医疗系统公司，东京，日本）成像板，并采用FCR 7000或FCR 9000处理成像数据。每张图像输出为一份硬拷贝。读取和输出的采样间距为0.1毫米。对于不可触及的肿瘤、直径小于2厘米的肿瘤、直径为2至5厘米的肿瘤以及直径大于5厘米的肿瘤，数字乳腺钼靶的乳腺癌诊断率分别为67%、95%、94%和100%，总体诊断率为94%。数字乳腺钼靶使我们能够建立目标导向的图像处理条件。数字乳腺钼靶的诊断率与屏-片乳腺钼靶相似，效果良好，预计在不久的将来会得到广泛应用。
