摘 要:目的 评价超声造影到达时间参数成像(At-PI)在鉴别乳腺良恶性病变中的价值。方法 选取有明确病理结果的64个病变。定性分析病变的灌注模式、颜色分布、灌注缺损和缺损边界,定量计算At-PI与常规超声图像上病变的最大长径比(MLA/U)、最大厚径比(MTA/U)、面积比(SA/U)和造影剂到达病变最早与最晚时间差的绝对值。分析定量参数评估乳腺良恶性病变的受试者工作特征曲线下面积。结果 At-PI相较于超声造影具有更好的操作者间一致性。灌注缺损、颜色分布、MLA/U、MTA/U和SA/U在乳腺良恶性病变间有显著差异。结论 At-PI有助于乳腺良恶性病变的鉴别诊断且一致性优于超声造影。Objective To evaluate the value of arrival-time parametric imaging(At-PI)in the differentiation of benign and malignant breast lesions.Methods Sixty-four lesions with pathological results were selected.Perfusion patterns,color spatial distribution for lesions,the perfusion defect,and defect boundary were analyzed qualitatively.The maximal length-diameter ratio of the lesion in At-PI and ultrasound images(UI,MLA u),maximal thickness-diameter ratio of the lesion in At-PI and UI(MTx/u),area ratio of the lesion in At-PI and UI(Sx u)and earliest-final arrival time difference(△T)were calculated quantitatively.The interobserver reproducibility for contrast-enhanced ul-trasound(CEUS)and At-PI was evaluated.The area under receiver operating characteristic curve were calculated for MLA/u,MTx/u,Sa/u,and△T.Results Good interobserver reproducibility for At-PI was identified.In At-PI,there was statistically significant difference in color spatial distribution for lesions,the perfusion defect,MLA/U,MTa/u,and Sa u between benign and malignant breast lesions.Conclusions At-Pl is helpful in distinguishing benign from ma-lignant breast lesions,and has better interobserver reproducibility than CEUS.
