Abstract

Objective: To assess lung lesions with quantitative diffusion MR imaging. Materials and Methods: We retrospectively evaluated 120 patients with pulmonary lesions undergoing diffusion-weighted MR imaging. The ADC values of lung lesions were calculated and correlated with biopsy results. Results: The ADC of benign lung lesions (2.03±0.09x10-3mm2/s) was significantly higher (P<0.001) than that of malignant lung tumors (1.11±0.25x10-3mm2/s). Selection of 1.37x10-3mm2/s as a cut-off point for differentiating malignant from benign lung lesions revealed an area under the curve of 0.94, an accuracy of 87.5 %, a sensitivity of 94.9 %, and a specificity of 73.1%. Conclusion: Quantitative diffusion MR imaging may be used for differentiation of benign from malignant lung tumors.

Özet

Amaç: Kantitatif difüzyon MR görüntüleme ile akciğer lezyonlarını değerlendirmek. Gereç ve Yöntem: Diffüz ağırlıklı MR görüntüleme yapılan, akciğer lezyonu olan 120 hasta retrospektif olarak değerlendirildi. Akciğer lezyonlarının görünür difüzyon katsayısı (ADC) değerleri hesaplandı ve biyopsi sonuçlarıyla korele edildi. Bulgular: Benign akciğer lezyonlarının ADC değeri (2.03±0.09x10-3mm2/s) malign akciğer lezyonlarına göre (1.11±0.25x10-3mm2/s) göre anlamlı derecede yüksekti (p<0,001). Kestirim değeri 1.37x10-3mm2/s alındığında malign ve benign akciğer lezyonlarının ayırımında eğrinin altında kalan alan 0,94, doğruluk % 87,5, duyarlılık % 94,9 ve özgüllük %73,1 bulundu. Sonuç: Kantitatif difüzyon MR görüntülemesi, benign ve malign akciğer tümörlerinin ayrımında kullanılabilir.
