Virtual touch tissue imaging quantification and contrast-enhanced ultrasonography in the differential diagnosis of benign and malignant breast non-mass-like lesions
摘要
Abstract
Objective To explore the value of virtual touch tissue imaging quantification(VTIQ) and contrast-enhanced ultrasonography(CEUS) in the differential diagnosis of benign and malignant breast lesions with non-mass type. Methods A retrospective analysis of 85 cases by conventional ultrasound examination for the type of breast lesions in patients of image data,with pathologic results as the gold standard,analysis of US,VTIQ,CEUS and VTIQ joint CEUS for the breast type value in the differential diagnosis of benign and malignant lesions. Results There were 46 benign cases and 39 malignant cases in 85 cases of breast non-mass lesions. The internal shear wave velocity (SWV) and SWV ratio of breast non-mass benign lesions were significantly lower than that of malignant lesions(3. 43 ± 0. 59 m/s vs 4. 76 ± 0. 95 m/s,1. 73 ± 0. 43 vs 2. 67 ± 0. 77). The sensitivity,specificity and accuracy of VTIQ in the diagnosis of breast non-mass-like lesions were 76. 9％,80. 4％ and 78. 8％ respectively. Type of breast malignant lesions CEUS was high-enhanced enhancement compared with glandular tissue around the contrast agent into early enhancement and immediately wash-out and more for the nonuniformity,around the lesions or internal contrast enhancement of blood vessels,the sensitivity of CEUS in the diagnosis of mammary gland non tumor lesions, specific degrees and accuracy were 79. 5％,80. 4％ and 80. 0％ respectively. VTIQ type combined with CEUS in the diagnosis of breast mass lesions sensitivity and accuracy of the specific degree were 89. 7％,93. 5％ and 91. 8％ respectively,the joint diagnosis efficiency was significantly higher than single use of CEUS or VTIQ (P< 0. 05),CEUS and VTIQ diagnostic value were significantly higher than the US (P < 0. 05). Conclusion CEUS,VTIQ type in breast tumors in the differential diagnosis of benign and malignant lesions has good diagnostic value,VTIQ joint CEUS complementary advantages,more comprehensive diagnostic information available pathological changes,the type of breast disease diagnosis accuracy is improved.关键词
