Testis elastikiyetinin testis ekojenitesinin histogram analizi ile karşılaştırılması

Abstract

ÖZET Amaç: Bu çalışmanın amacı testis dokusu elastikiyeti ile testis eko sinyallerinden elde edilen ultrason (US) histogram analizi arasındaki ilişkiyi değerlendirmektir. Amaç, kantitatif doku analizinin geleneksel US bulgularını tamamlayıp tamamlayamayacağını araştırmaktır. Gereç ve Yöntem: 92 testisi olan 46 hasta B-mod ultrason ve gerinim elastografisi (SE) kullanılarak incelendi. Her testis için ortalama, standart sapma, çarpıklık, basıklık ve entropi gibi histogram parametrelerini çıkarmak için transvers US görüntüsü analiz edildi. SE, testis elastikiyetini ölçmek için kullanıldı. Bulgular: Histogram analizi yaş ile testis dokusunun homojenizasyonu arasında önemli bir korelasyon gösterdi (r = 0,444; p<0,001). Gerinim oranları ortalama ilgi alanı (ROI) sinyal değeri ile pozitif korelasyon gösterdi (r = 0,627; p<0,001), ortalama entropi değerleri ile gerinim oranları arasında ise ters bir korelasyon bulundu (r = -0,683; p<0,001). Sonuç: Bu bulgular daha yüksek eko entropisinin testis elastikiyetini artırdığını göstermektedir. Bu kantitatif analiz, testis fonksiyonunu değerlendirmek için yeni bir objektif yöntem sunar ve geleneksel ultrason tekniklerine tamamlayıcı veriler sağlar.

Comparison of testicular elasticity with histogram analysis of testicular echogenicity

Abstract

ABSTRACT Aim: This study aims to evaluate the relationship between testicular tissue elasticity and ultrasound (US) histogram analysis obtained from testicular echo signals. The goal is to explore whether quantitative texture analysis can complement traditional US findings. Materials and Methods: 46 patients with 92 testis were examined using B-mode ultrasound and strain elastography (SE). A transverse US image was analyzed for each testis to extract histogram parameters such as mean, standard deviation, skewness, kurtosis, and entropy. SE was used to measure testicular elasticity. Results: Histogram analysis showed a significant correlation between age and homogenization of testicular tissue (r = 0.444; p<0.001). Strain ratios were positively correlated with the mean region of interest (ROI) signal value (r = 0.627; p<0.001), whereas an inverse correlation was found between the mean entropy values and strain ratios (r =-0.683; p<0.001). Conclusion: These findings suggest that higher echo entropy increases testicular elasticity. This quantitative analysis offers a new objective method for assessing testicular function and provides data complementary to traditional ultrasound techniques.
