    Ultrasound demonstrated higher sensitivity for diagnosing breast tumors compared to mammography and aspiration biopsy. Ultrasound histography can improve accuracy, especially for larger tumors.

    Area of Science:

    • Oncology
    • Radiology
    • Pathology

    Background:

    • Accurate preoperative diagnosis of breast lesions is crucial for effective treatment planning.
    • Conventional imaging techniques like mammography, ultrasound, and aspiration biopsy have varying diagnostic capabilities.

    Purpose of the Study:

    • To compare the effectiveness of preoperative diagnostic techniques for breast nodes.
    • To evaluate a novel ultrasound histography technique for enhancing diagnostic specificity.

    Main Methods:

    • A comparative analysis involving 110 females with breast cancer and 306 with benign breast tumors.
    • Assessment of mammography, ultrasound, and aspiration biopsy.
    • Introduction of ultrasound histography for improved echography specificity.

    Main Results:

    • Diagnostic sensitivity: mammography (82.8%), ultrasound (88.3%), aspiration biopsy (69.3%).
    • Reduced informative value of mammography and aspiration biopsy in reproductive-aged females, particularly with hyperplastic processes.
    • Ultrasound sensitivity increases with tumor size, but specificity decreases.

    Conclusions:

    • Ultrasound is a sensitive tool for breast tumor diagnosis, with sensitivity increasing for larger tumors.
    • Ultrasound histography is beneficial for improving diagnostic specificity in cases of larger breast tumors.
