The efficacy of strain elastography and shear-wave elastography in the evaluation of neoadjuvant chemotherapy for patients with locally advanced breast cancer

Two group patients were performed conventional ultrasound and elastography examination before NAC (pre-NAC),after the second (post-2^nd-NAC), and the fourth cycles of NAC(post-4^th-NAC),including 40 cases of 40 breast cancer patients (age range, 25-72 years) in Strain Elastography (SE) group and 21 cases of 20 breast cancer patients (age range,31-67 years) in shear-wave elastography (SWE) group. Changes in elastographic parameters (elasticity grading and strain ratio in SE group, the maximum elastic value and the average elastic value in SWE group) related to tissue biomechanical properties were then determined and compared to clinical and pathologic tumor response after mastectomy. @font-face {font-family:宋体; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;}@font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face {font-family:"\@宋体"; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:宋体; mso-fareast-theme-font:minor-fareast;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; font-family:Calibri; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi; mso-font-kerning:0pt;}div.WordSection1 {page:WordSection1;}
