冠状切面超声造影评估乳腺病灶周围血管

Evaluation of surrounding vessels of breast lesions with contrast-enhanced ultrasound in coronal plane

目的评估冠状或近似冠状切面超声造影显示乳腺病灶周围血管的意义。方法用超声造影观察45例患者的46个乳腺病灶,其中恶性肿瘤25个,良性病变21个。通过冠状或近似冠状切面计数病灶周围血管的数目,评估血管的形态学特征。结果冠状和近似冠状切面可清楚显示病灶周围血管,恶性肿瘤病灶周围血管扭曲,管径扩张,血管的数目较良性病灶多(P=0.000)。结论冠状或近似冠状切面显像是评估乳腺病灶周围血管的良好方法,超声造影是诊断和鉴别诊断乳腺良恶性病变的有效手段。

Objective To evaluate the diagnostic value of surrounding blood vessels of breast lesions using real-time contrast-enhanced ultrasound in coronal plane or approximately coronal plane. Methods Forty-six breast lesions in 45 patients underwent real-time contrast-enhanced ultrasonography were grouped as malignant lesions （ n = 25） and benign lesions（ n = 21）. The vessels surround every lesion were counted and assessed in coronal plane or approximately coronal plane. Results Convergent vessels around breast lesions could be clearly demonstrated in coronal plane or approximately coronal plane. Contrast-enhanced ultrasound showed an increased number of surrounding vessels in malignant lesions in comparison to benign lesions（ P = 0.000）. Criteria such as large vessel diameters and tortuous vessel course also could be used to differentiate benign from malignant breast lesions. Conclusions It is a useful method to evaluate surrounding blood vessels of breast lesions in coronal plane or approximately coronal plane. Real-time contrast-enhanced ultrasound may become a good tool in breast lesion diagnosis and in differentiating benign from malignant lesions.
