Abstract
This study investigates the role of spectral analysis mammography in evaluation of breasts harboring masses through accurate quantification of the fibroglandular tissue volume aided by the photon counting spectral detectors of the mammogram and then automated calculations of the Volumetric breast density, which is a true physical measure, can be obtained. In our study we present a new classification of breast density across the automated density grades according to the measured volumetric breast density, this classification distributes the measured breast density to non-dense breasts (automated density grade 1 & 2) and dense breasts (automated density grades 3 & 4) paving the way for refined risk assessment and personalized care. Our study involved 95 ladies, their age ranging from 32 to 73 years. 7 of them had mastectomy on the right side and 11 of them had mastectomy on the left side due to previous malignant masses. The total number of examined breasts was 171; 108 normal breasts, 21 breasts with benign cystic masses (19 mammary fibrocystic changes and 2 breast collections), 14 benign solid masses (13 fibroadenomas and 1 hamartoma) and 28 with malignant masses (1 DCIS and 27 invasive mammary carcinomas).3 breasts had unsuccessful automated VBD readings due to technical problems. The distribution of our patients’ breasts density According to the automated density grades was; 3 breasts had missed readings due to technical problems. (7 breasts; 4.2%), (9 breasts; 5.4%), (67 breasts; 39.9%) and (58 breasts; 50.6%) matching automated density grades 1, 2, 3 and 4 respectively.
