Contraste hepatobiliar: diagnóstico diferencial das lesões hepáticas focais, armadilhas e outras indicações

Abstract: The characterization of focal liver lesions is very important. Magnetic resonance imaging is considered the best imaging method for evaluating such lesions, but does not allow for the diagnosis in all cases. The use of hepatobiliary contrast agents increases the diagnostic accuracy of magnetic resonance imaging and reduces the number of non-specific liver lesions. The main indications for the method include: differentiation between focal nodular hyperplasia and adenoma; characterization of hepatocellular carci… Show more

“…MRI is considered the imaging technique with the best Se and Sp for FLL diagnosis [15]. When compared to US and CT, MRI has a better Se and Sp for the diagnosis of hepatocellular carcinoma (HCC); the detection of HCC in the cirrhotic liver is better by means of MRI (72%) as compared to both CT (65%) and US (48%) examinations [16].…”

“…MRG, özellikle küçük boyuttaki (≤1 cm) karaciğer metastazlarının saptanmasında ve karakterize edilmesinde sensitivitesi ve spesifitesi en yüksek metod olarak kabul edilmektedir [4,6,7]. Hepatobiliyer kontrast maddeler ve DAG özellikle küçük boyuttaki bu metastazların saptanmasında sensitiviteyi arttırmaktadır [12][13][14][15]. Günümüzde Gadobenat dimeglumin (Gd-BOPTA; Multi-Hance, Bracco Imaging, Milan, Italy) ve Gadoxetik asid (Gd-EOB; Primovist, Bayer Schering Pharma AG, Berlin Germany) olmak üzere iki farklı hepatobiliyer paramagnetik gadolinyum şelatı kontrast madde bulunmaktadır.…”

“…iken Gd-BOPTA'dan sonra 1-2 saat kadardır. Ancak Gd-BOPTA daha yüksek relaksiviteye sahiptir [9][10][11][12][13][14]. Hepatobiliyer fazda sağlıklı karaciğer belirgin kontrast tutarak hiperintens, hem hipovasküler hem de hipervasküler metastazlar ise fonksiyone hepatosit veya safra yolu içermediğinden kontrast tutulumu göstermeyerek hipointens izlenmektedir.…”
