Summary
High-frequency ultrasound combined with fine-needle aspiration biopsy (FNAB) significantly improves the diagnosis of complex breast nodules, achieving 96.7% accuracy. This combination is crucial for accurate breast lesion assessment.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Complex breast nodules require accurate diagnostic methods.
- Distinguishing between benign and malignant complex breast lesions is clinically important.
Purpose of the Study:
- To evaluate the diagnostic role of high-frequency ultrasound (7.5 MHz) in conjunction with fine-needle aspiration biopsy (FNAB) for complex breast nodules.
- To compare the efficacy of ultrasound, FNAB, mammography, and pneumocystography in diagnosing these lesions.
Main Methods:
- Sixty patients with complex breast nodules were analyzed.
- All patients underwent ultrasound-guided FNAB.
- Mammography and pneumocystography were performed in a subset of patients for comparison.
Main Results:
- Ultrasound identified lesions in all patients and diagnosed their nature in 73%.
- Combined ultrasound and FNAB achieved a diagnostic accuracy of 96.7%.
- Mammography identified lesions but often failed to reveal their complex nature; pneumocystography provided no additional information over ultrasound.
Conclusions:
- Combined ultrasound and FNAB are essential for diagnosing complex breast lesions, largely replacing pneumocystography.
- Ultrasound is reliable for typical cystic lesions, while FNAB is crucial for atypical cases and solid components.
- Mammography's role is limited to detecting specific malignant features not visible on ultrasound.
