Özet

Amaç: Bu çalışmadaki amacımız, tiroid nodüllerinde benignmalign ayrımında US elastografinin katkısını araştırmaktır. Gereç ve yöntem: Kliniğimize tiroid ince iğne aspirasyon biyopsisi (İİAB) için refere edilen 52 hasta çalışmaya dahil edildi. 56 tiroid nodülü çalışmaya dahil edildi ve tüm nodüller B-mod ultrasonografi ve elastografi ile değerlendirildi.İİAB ve elastografi sonuçları karşılaştırıldı.Elastisite skorlaması 1' den (nodülün tümünde elastisite var) 5' e kadar (nodülde ve posterior gölgelenmede elastisite yok) olacak şekilde yapıldı. Bulgular: 49 benign nodülün 48' inde skor1-3 arası, 7 malign nodülün 5' inde skor 4-5 olarak değerlendirildi (p<0.05). Sensitivite, spesifite, pozitif prediktif değer (PPV) ve negatif prediktif değer (NPV) sırasıyla; %71, %97, %83, %68 olarak hesaplandı. Elastografinin genel gücü (test geçerliliği) %94 olarak Sonuç: Ultrason elastografi, tiroid kanseri ayırıcı tanısında faydalı bir yöntemdir.
