Purpose High-frequency ultrasound (US) transducers are increasingly being integrated into clinical practice due to their ability to provide high-resolution imaging of millimetric and superficial anatomical structures. Their enhanced spatial resolution makes them particularly useful for evaluating delicate tissues, fine vascular networks, and small pathological changes that may not be as clearly visualized with conventional ultrasound probes [1, 2].Despite these advantages, there is currently limited research on their specific application in assessing the retroareolar-nipple region, a complex anatomical area characterized by intricate...
Read more Methods and materials A highly experienced breast radiologist performed the ultrasound examinations and systematically collected still images of retroareolar findings using two different probes: a classic linear probe (CLP) with a frequency of 14 MHz (LA2-14A) and a high-frequency probe (HFP) with a frequency of 22 MHz (LA3-22AI). The radiologist carefully selected and stored the images that best characterized the anatomical structures and pathological features of the findings, ensuring optimal representation of the lesions for evaluation.To assess the diagnostic consistency and accuracy of...
Read more Results A total of 80 ultrasound still images, derived from 40 individual cases, were systematically evaluated by the radiologists. Each case contributed two images—one acquired using the classic linear probe (CLP) and the other obtained with the high-frequency probe (HFP)—ensuring a direct comparison of imaging quality and diagnostic consistency between the two modalities.The overall inter-reader agreement across all participants was found to be "substantial" for both ultrasound probes, with a kappa coefficient (κ) of 0.71 for CLP and a slightly higher...
Read more Conclusion The inter-reader agreement, as calculated using Cohen’s Kappa and Fleiss' Kappa coefficients, was slightly higher for the high-frequency probe (HFP) compared to the values obtained for the classic linear probe (CLP). This finding suggests that the use of high-frequency ultrasound enhances consistency among radiologists in interpreting retroareolar lesions, a region that is particularly challenging due to its complex anatomical structure and the presence of imaging artifacts.The improved agreement indicates that HFP provides clearer, more detailed visualization of anatomical features, allowing...
