Shear Wave Elastography (SWE): An Analysis of Breast Lesion Characterization in 83 Breast Lesions
چکیده انگلیسی
Qualitative and quantitative shear wave elastography (SWE) criteria were assessed to differentiate between malignant and benign breast lesions. This prospective study included 83 lesions. SWE features measured included maximal stiffness values inside the lesion (Elesion) and in the peri-lesion area (Eperilesion) and ratio values (Rlesion and Rperilesion) according to the formula Elesion or Eperilesion/Efat, with Efat corresponding to normal fatty tissue. We compared ultrasonography (B-mode), SWE and histologic sizes. With qualitative and quantitative SWE analysis, sensitivity was 94% and specificity 73%. Malignant lesions appeared more heterogeneous, with higher stiffness and ratio values than benign lesions (p < 0.001). For malignant lesions, SWE size was better correlated to histologic size than B-mode size. Using benign SWE signs to selectively downgrade category 4a and 4b lesions, the specificity improved from 13% to 51% without loss in sensitivity (100%) compared to ultrasound.
