- W3021827319 abstract "Objectives: Shortening of the hepatic transit time (HTT) indicates metastatic spread to the liver. A HTT of 15s in patients without liver lesions, and 6.5s in patients with known liver metastasis was shown. Is there an influence of benign liver lesions on the HTT? Methods: We measured the HTT of an echo enhancer in pulse inversion mode on the basis of time intensity curves (TIC) in patients with focal liver lesions. The hepatic artery and a branch of the hepatic vein were visualized simultaneously in an intercostal section. The difference of the arrival time of the echo enhancer in the hepatic vein and the hepatic artery supplied the real HTT. Results: Of 42 patients enrolled in this study, 19 patients had metastases in the liver. Benign lesions were found in 23 patients. The mean HTT in patients with liver metastasis was 6.4 s, in patients with benign lesions it was significantly longer 10.4 s (p < 0.001). None of the patients with liver metastasis had an HTT of more than 10 s. Conclusions: Measurement of HTT allows ruling out liver metastasis. Benign liver lesions do lead to a shortening of HTT, less than in patients with liver metastasis." @default.
