Aim and objectives: To Assess the role of Mammography, Tomosynthesis, Ultrasonography and Elastography in evaluation of breast lesions.
Methods: Prospective study was carried out on 100 patients of breast lesions in Dr. D.Y. Patil Medical College, Hospital and Research Centre, Pimpri, Pune over a period of two years. Patients were evaluated with Mammomatand Arieta s60 Mammography and Ultrasound machine respectively. Characteristics of breast lesions on mammography, Tom synthesis, ultrasonography and Elastography was studied. Comparison was made with histopathological reports to study accuracy of various above mentioned modalities in differentiating benign and malignant breast lesions.
Results: 100 cases were included in our study. Out of the total 100 cases, mammography was able to detect calcifications in 8 cases while Tomosynthesis could pick up the calcifications in additional 4 cases, whereas ultrasound was able to detect calcifications in only 6 cases, thus making Tom synthesis a better modality to detect calcifications, and ultrasound not a very efficient modality to detect calcification. Out of the total 100 cases Elastography was performed in only 70 cases .Elastography was performed by both qualitative and semi quantitive methods. Strain ratio was not calculated in cysts (10 cases).Only BGR sign was seen in cysts. Strain ratio was less than 3.1 in 33 cases out of total 60 cases. Strain ratio was more than 3.1 in 27 cases out of total 60 cases. BGR sign was seen in remaining 10 cases in our study we found that Elastography was a better modality in detecting malignancy than ultrasound B-mode alone.
Conclusion: A combined approach using sonography, Elastography and mammography in evaluation of patients presenting with palpable breast masses is better than individual modalities.
