Abstract:
Objective: To observe growth orientation of breast masses with contrast-enhanced ultrasonography (CEUS) combined with breast MRI. Methods: A total of 103 patients with conventional ultrasound (CUS) showed non-parallel-orientation growth breast masses were enrolled and divided into benign group (n=35) and malignant group (n=68). Tumor growth orientation shown with CEUS was observed in the same section. Twenty patients underwent MRI, the relationships between mass and adjacent skin were observed and compared with mass location shown on CEUS. Results: After CEUS, growth orientation was changed in 4 cases but not in 31 cases of benign group, while in malignant group, changes of tumor growth orientation was noticed in 59 cases but not in 9 cases, indicating that the growth orientation of malignant tumor was more easily to change than benign ones (χ2=55.210,P<0.001). The sensitivity, specificity, positive predictive value and negative predictive value of CEUS in diagnosis of benign and malignant breast masses was 93.65% (59/63), 77.50% (31/40), 86.76% (59/68) and 88.57% (31/35), respectively. MRI showed consistent Results: with CEUS for growth orientation in 19 cases (P=0.500). CEUS was consistent with MRI in determination of tumor location (Kappa=0.828). Conclusion: Among breast masses CUS showed non-parallel position, most benign ones had some founding in CEUS, but most malignant breast masses showed parallel growth in CEUS. CEUS has good consistency with MRI in determining the orientation of breast masses, which is more reliable than CUS in evaluation on the growth location of breast tumors.
