Columbia University Medical Center, Dr. Melton reports, digital mammography images via broadband Internet and accurate long-distance transmission, the doctor can be realized off-site time sheet.
Researchers region-wide digital mammography X-ray images (FFDM) images of remote transmission accuracy, transmission speed, direct secure connection and digital computer-aided detection (CAD) system interface, etc. were studied. They will test two FFDM units, a CAD system and the primary diagnostic centers and 110 miles of breast imaging assessment of workstations connected via a wired Internet access with multiple virtual private network, without the compressed (an average of 125 MB) of the image data assessment of real-time transmission to the remote workstation. The image transmission speed, image quality, CAD mark and image interpretation for analysis.
A total of 1314 cases of patients being remote transmission of data and interpretation. Each image transmission time less than 45 seconds. Visual observation of the remote workstation image in line with the original image. 12 cases of the data file size for comparison, as compared with the original case data, the data bytes of deviation is less than 0.2% (P <0.001), no data is lost after transmission. Using two different tests on the 150 randomly selected cases to verify results showed that 328 CAD marks in the original image and the image after transmission line between the rate of 100%. By independent experts of the two cases of data interpretation, there are 147 cases in 150 cases results are consistent with the remaining three cases the deviation is caused by differences in the interpretation, has nothing to do with the image quality.
In the United States, once because of well-trained experts in mammography and read the insufficient number of films, while the impact on the conduct of breast cancer screening. The study showed that with the popularity of high-speed Internet, through the establishment of regional long-range clinical workstation, can improve the accuracy and effectiveness of breast screening to help health care resources to underserved areas with screening.
