Diagnostic efficacy of ultrasound, ultrasound elastography and magnetic resonance imaging for breast lesions

Abstract

Background: The present study was conducted for comparing the diagnostic efficacy of ultrasound, ultrasound elastography and magnetic resonance imaging for breast lesions. Materials & methods: A total of 100 subjects were enrolled. Complete demographic details and clinical details of all the subjects were enrolled. All the patients were subjected to B-mode USG assessment. US Elastography was also done. The two-dimensional USG was followed by Real Time ultrasound elastography. The stiffness of the lesion was evaluated. All patients were placed prone on a 0.5 Tesla MRI scanner equipped with a dedicated breast surface coil. The lesion was categorized as benign, probably benign, malignant and probably malignant. Fine needle aspiration cytology (FNAC) or biopsy was performed and the specimen was evaluated cytologically/histopathologically to confirm the diagnosis. All the results were recorded and analysed by SPSS software. Results: Sensitivity and specificity of USG was 78.6 percent and 86.2 percent respectively. Sensitivity and specificity of Elastography was 89.5 percent and 92.6 percent respectively. Sensitivity and specificity of MRI was 96.2 percent and 93.1 percent respectively. Conclusion: MRI was most sensitive and most specific followed by USG elastography.
