“…This abnormal blood flow may be determined using imaging techniques such as dynamic hepatic scintigraphy (4) or duplex ultrasonography (5), techniques that are not only expensive but also operator dependent. Furthermore, this abnormal hepatic haemodynamics may be useful in predicting poor outcome in patients with colorectal cancer (6).…”

“…HPI was measured by dynamic hepatic scintigraphy, as reported previously from the authors’ institution [ 5, 13]. Subjects were starved overnight to avoid the increase in portal flow after eating and were then positioned supine over a large field of view gamma camera to visualize the posterior aspects of the lung bases, liver and kidneys.…”

“…The HPI was calculated as the ratio of the hepatic arterial gradient to the hepatic arterial plus portal venous gradient and therefore reflected the fraction of total liver blood flow that arrived via the hepatic artery. HPI >0.42 was considered to be abnormally elevated, as previously established in the authors’ institution [ 5].…”

“…Eine möglicherweise bestehende, signifikante Veränderung der arteriellen Leberperfusion beim Vorliegen von okkulten Metastasen bei kolorektalem Karzinom könnte die DS als ideales Screeningverfahren für diese Gruppe von Tumorpatienten etablieren durch Erfassung des Doppler-Perfusions-Index (DPI) [5,6]. Neben anderen Verfahren, wie der dynamischen Leberszintigraphie [7,8] oder KM-gestützten CT-und MRI-Untersuchungen [9], konnte die DS beim Vorliegen von apparenten primären oder sekundären Lebermalignomen ebenfalls eine charakteristische Verschiebung der Perfusion zugunsten des arteriellen Anteils detektieren.…”
