ABSTRACT
Background: Gray scale sonography is an
important diagnostic tool for the detection of malignant breast tumour. Objective: The purpose of the present study was to find out the diagnostic validity
gray scale sonography to detect malignant lesions of breast. Methodology: This
cross-sectional study was carried out in the department of Radiology and
Imaging, in collaboration with the department of Surgery and Pathology at
Banghabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from July 2008 to
June 2009 for a period of one year. Women presented with clinically suspected
breast mass from outpatients’ department (OPD) or inpatient department (IPD)
were purposively selected and was Ultrasonographic diagnosis. 2-D Real-Time
B-Mode Ultrasonographic examinations were done using high frequency (7.5 MHz)
linear transducer. Result: Test of validity was done for color Doppler
Sonographic findings in evaluation of benign and malignant breast lesion. Out
of 50 cases, 23 cases were true positive; 4 cases were false negative; 1 case
was false positive; 22 cases were true negative confirmed by histopathology.
Here sensitivity and specificity of Gray scale ultrasonography were 85.18% and
95.0% respectively. Here accuracy of Gray scale study was 90.0%. Positive
predictive value was 95.83% and negative predictive value was 84.61%. Conclusion: Gray scale ultrasonography is a useful method in the differentiation
between benign and malignant breast masses.
