Materials and Methods: Using the digital mammographic system SenoScan (Fischer Imaging, Denver, USA), 50 diagnostic breast specimens with microcalcifications were visualized in both standard mode (pixel size 54 pm) and high resolution mode (pixel size 27 pm). The resulting radiographs were displayed 1:1 on a monitor. Standard mode images (pixel size 54 mu m) were additionally displayed in a 2:1 mode. A total of 5 readers with different mammographic experience analyzed the type of the microcalcifications on the basis of the different display modes. The images were presented randomly. The findings were subsequently compared to the histology. Results: The high resolution mode yielded slightly but not significantly better results than the standard mode on average for all 5 readers. Compared to a sensitivity of 80% and a specificity of 72% (PPV=74%, NPV=78%) in the standard mode, the high resolution mode provided a sensitivity of 86% and a specificity of 74% (PPV = 77%, NPV = 83%). The standard mode images on a 2:1 monitor display yielded 84% and 74% (PPV = 76%, NPV = 82%). Conclusion: The high resolution mode did not significantly increase the sensitivity and specificity of the microcalcification reading. A similar improvement was achieved by the 2:1 display mode, i.e. digital monitor zooming. For the clinical situation this means that there is no diagnostic advantage from using a high resolution target view with this mammographic system."],["dc.identifier.doi","10.1055/s-2007-962980"],["dc.identifier.isi","000246689800006"],["dc.identifier.pmid","17436183"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/51524"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1438-9029"],["dc.title","Comparing the clinical value of spot view mammography with reduced pixel size to monitor zooming by reporting microcalcifications in digital mammography"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

The aim of this retrospective clinical study was to compare the diagnostic accuracy of the novel 50 mu m FFDM (full-field digital mammography) system (DR) with an established 70 mu m system (DR) in the differential diagnosis between benign and malignant clusters of microcalcification (n=50) (BI-RADS (TM) T classification 4/5) and to assess the possible incremental value of the 50 mu m pixel-pitch on specificity. Material and methods. From March 2009 to September 2009, 50 patients underwent full-field digital mammography (FFDM) (detector resolution 70 mu m) (Novation, Siemens, Erlangen, Germany). As there were suspicious signs of microcalcification classified with BI-RADS (TM) 4/5 after diagnosis and preoperative wire localization, control images were made with the new FFDM system (detector: resolution 50 mu m) (Amulet, Fujifilm, Tokyo, Japan) with the same exposure parameters. The diagnosis was determined after the operation by five radiologists with different experience in digital mammography from randomly distributed mediolateral views (monitor reading) whose results were correlated with the final histology of all lesions. Results. Histopathology revealed 19 benign and 31 malignant lesions in 50 patients after open biopsy. The results of the five readers showed a higher sensitivity of the new FFDM system (80.0%) in the ability to recognize malignant microcalcification in comparison to the established system (74.8%). The specificity (75.8 versus 71.6%) was slightly higher for the new system but hese results were not statistically significant (p<0.001). Considering the diagnostic accuracy, the new system (detector: resolution 50 mu m) was also slightly superior to the well-known system (detector: resolution 70 mu m) (80.1% versus 76.4%). Conclusions. Our study has shown that the new full-field digital mammography system using the novel detector compared with the already established FFDM system with respect to the assessment of microcalcification is at least equivalent."],["dc.identifier.doi","10.1007/s00117-010-2078-6"],["dc.identifier.isi","000289488700008"],["dc.identifier.pmid","21069511"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/24033"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1432-2102"],["dc.relation.issn","0033-832X"],["dc.title","Comparison of dignity determination of mammographic microcalcification with two systems for digital full-field mammography with different detector resolution.

The article describes an experimental phantom study of a system for digital full field mammography with a new digital detector with a double plate of pure selenium. Materials and methods. The experiments were carried out with the new full field digital mammography system Amulet from FujiFilm. This system has a new detector (18x24 cm(2)) on the basis of highly purified amorphous selenium (a-Se) with a pixel size of 50 mu m. The x-rays are converted into electric signals in the first plate which are read into the second plate with the help of an optical switch and demonstrated in the form of an image. In this way a better pixel size/volume and signal-to-noise ratio should be achieved. The object of the investigation was the Wisconsin Mammographic Random Phantom, Model 152 A (Technical Performance Mo/Mo, 28 kV, 100 mAs). Five investigators with different experiences in mammography each received three images on a monitor with different random positions of the simulated lesions in the phantom for assessment. The detection rates were compared under the same conditions with the results of two other full field digital mammography systems. Results. The median detection rate for all images and investigators for the new doubled plated a-Se detector with optical switch was 98.7%. For both other systems with a-Si or and a-Se detectors the detection rate was 89.8% or 97.3%, respectively. There were no significant differences in the detection rate of the simulated breast lesions for all three systems considering the interobserver and intraobserver variation. Conclusion. The first phantom study for the detection of simulated breast lesions with the new full field digital mammography system Amulet demonstrates equivalent results with the other systems used in the clinical routine.
