However, following initial euphoria, things quietened down about DBT -- mainly because the mandatory quality control guidelines and FDA approval for the US market are lacking. Italian firm I. A year later, they were the first, worldwide, to use FFDM for stereotactic biopsy examinations. Indeed, I. Now, they are conducting the largest multicentre clinical trial on DBT technology. Involved are the university radiology departments of Bologna, Milano, Udine, Stockholm and Maastricht.
Multiple cases were obtained from each virtual patient image and used for image interpretation. A indicates the area under the receiver operating characteristic curve; 3-D, 3-dimensional. A and B, Digital mammography DM A and selected digital breast tomosynthesis DBT slice B of a case corresponding to a breast with scattered areas of fibroglandular density containing a microcalcification cluster inserts. C and D, Digital mammography C and selected DBT slice D of a case corresponding to a breast with scattered areas of fibroglandular density containing a spiculated mass lesion arrowheads. Lesions have been made more conspicuous for display purposes by artificially increasing their radiography attenuation during image acquisition.
Digital breast tomosynthesis DBT has improved conventional mammography by increasing cancer detection while reducing recall rates. However, these benefits come at the cost of increased radiation dose. Synthesized mammography s2D has been developed to provide the advantages of DBT with nearly half the radiation dose.
