The evaluation of mammographies carried out by conventional technique (standard imaging and focal imaging with 1.9x magnification) should be compared with a direct magnification image (standard imaging with 1.7x magnification, focal imaging with 4x magnification and preparation imaging with 7x magnification) provided by the mammographic device DIMA Plus M11 of the company feinfocus Medizintechnik.
Out of over 1,000 mammographies (DIMA technique) 50 histologically proved cases were selected for evaluation. Within a three months period these cases underwent conventional standard mammography as well as 1.9x magnification and DIMA-mammographies. The second X-ray was carried out when it was necessary for a pre-operative marking.
When mammographies of mammaries, which were radiologically transparent and easily compressible, where taken by DIMA-technique, they showed a distinct advantage, especially in unclear micro-calcification cases, in comparison to the mammographies carried out by the conventional standard imaging.
Direct magnification images carried out by DIMA Plus M11 provide a better breast cancer diagnostic. This refers in particular to focal images with 4x magnification and to digital mammography, which is yet being developed.
将采用传统技术(标准成像和1.9倍放大率的局部成像)进行的乳房X线摄影评估结果与feinfocus Medizintechnik公司的DIMA Plus M11型乳房X线摄影设备提供的直接放大图像(1.7倍放大率的标准成像、4倍放大率的局部成像和7倍放大率的准备成像)进行比较。
从1000多例乳房X线摄影(DIMA技术)中选取50例经组织学证实的病例进行评估。在三个月的时间内,这些病例接受了传统标准乳房X线摄影、1.9倍放大率乳房X线摄影以及DIMA乳房X线摄影。在需要进行术前标记时进行第二次X线检查。
当采用DIMA技术对放射学上透明且易于压迫的乳房进行乳房X线摄影时,与传统标准成像进行的乳房X线摄影相比,它们显示出明显优势,尤其是在微钙化情况不明确的病例中。
DIMA Plus M11进行的直接放大图像能提供更好的乳腺癌诊断。这尤其适用于4倍放大率的局部图像以及尚在开发中的数字乳房X线摄影。
