Abstract:
Objective
To evaluate the clinical significance of breast-specific gamma imaging (BSGI)in diagnosis of breast cancer.
Methods
We performed a perspective study of 136 patients with indeterminate breast lesions who underwent dual-phase BSGI in our hospital from March 2012 to December 2013. All included lesions were confirmed by pathology. BSGI was evaluated based on the visual interpretation and dual-phase semi-quantitative indices of lesion to non-lesion (L/N) ratio, which were compared with pathological results.Difference of L/N ratio of BSGI between benign and malignant breast lesions was analyzed by Mann-Whitney U nonparametric test.
Results
The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of BSGI in the diagnosis of breast cancer were 95.1%(97/102), 73.5%(25/34), 89.7%(122/136), 91.5%(97/106) and 83.3%(25/30), respectively. L/N ratio of BSGI in breast cancer was significantly higher than that of benign tumor (2.98±1.29 vs 0.95±1.11, Z = -7.125, P = 0.000).
Conclusion
BSGI has a significant clinical value in the diagnosis of breast cancer.
