Karaciğer solid kitlelerinin renkli doppler ultrasonografi bulguları

Solid karaciğer kitlelerinin renkli Doppler ultrasonografi (RDUS) bulgularının ve bunların ayırıcı tanıya katkılarının araştırılması. Materyal ve Metod: Karaciğer solid kitlesi olan 35 olgu, RDUS ile prospektif olarak değerlendirildi. Lezyonların spektral özellikleri, vasküler paternleri ve vasküler morfolojileri belirlendi. Tüm lezyonlara biyopsi ve/veya görüntüleme yöntemleri ile tanı konuldu. Lezyonlar tanılarına göre gruplandırıldı ve RDUS bulguları istatistiksel analizlerle değerlendirildi. Bulgular: Otuzbeş olgunun 18'i hepatoselüler karsinom (HSK); 10'u hemanjiyom; 7'si metastatik karaciğer kitlesi tanısı aldı. Metastazlı 6, hemanjiyomlu 1 ve HSK'lı tüm olgularda kanlanma saptanırken, hemanjiyom tanısı alan 9 olguda ve metastaz tanısı alan 1 olguda renk kodlaması elde edilemedi. Primer ve metastatik lezyonlardan elde edilen vasküler patern/vasküler morfoloji ile (p>0.05) pik sistolik hız ve rezistif indeks değerleri arasında (p>0.05) anlamlı bir farklılık saptanmazken, karaciğerin benign ve malign solid lezyonları arasındaki fark anlamlıydı (p0.05), primer ve metastatik lezyonlar arasında ayrım yapılabilir (p

Color doppler ultrasonographic findings of solid liver masses

Detection of color Doppler ultrasonographic (CDU) findings of the solid liver masses and contribution of these findings to differential diagnosis. Material and Methods: Thirty-five patients with solid liver mass were evaluated prospectively. Spectral Doppler properties, vascular patterns and vascular morphologies of these lesions were determined. The diagnoses of the lesions were made with biopsy and/or imaging modalities. These lesions were classified according to their diagnoses and CDU findings were analyzed statistically. Results: Of the 35 patients with liver masses, 18 were diagnosed as hepatocellular carcinoma (HCC); 10 as hemangioma; and 7 as metastasis. As vascularization was determined in 6 with metastasis, 1 with hemangioma and all patients with HCC, no color flow signal was detected in 9 with hemangiomas and one with metastasis. Although there was no statistical difference in vascular pattern, vascular morphology, peak systolic velocity and resistive index values of primary and metastatic lesions (p>0.05), there was a statistically significant difference between benign and malignant solid liver lesions by using these values (p
