“…Furthermore, the delineation of the segmental localization of metastases by imaging the hepatic arterial and portal venous anatomy and the accurate volumetric measurement of tumor and normal liver achieved with CT are both crucial in the surgical planning of CRLM resection [4] . The reported sensitivity of contrast enhanced CT for liver metastases is 68%-85% [21][22][23][24][25] . Despite the high resolution of CT liver imaging, some reports have shown that this modality may still miss up to 20% of liver metastases [22,26] .…”

The development of ultrasound contrast agents with excellent tolerance and safety profiles has notably improved liver evaluation with ultrasound (US) for several applications, especially for the detection of metastases. In particular, contrast enhanced ultrasonography (CEUS) allows the display of the parenchymal microvasculature, enabling the study and visualization of the enhancement patterns of liver lesions in real time and in a continuous manner in all vascular phases, which is similar to contrast-enhanced computed tomography (CT) and contrast-enhanced magnetic resonance imaging. Clinical studies have reported that the use of a contrast agent enables the visualization of more metastases with significantly improved sensitivity and specificity compared to baseline-US. Furthermore, studies have shown that CEUS yields sensitivities comparable to CT. In this review, we describe the state of the art of CEUS for detecting colorectal liver metastases, the imaging features, the literature reports of metastases in CEUS as well as its technique, its clinical role and its potential applications. Additionally, the updated international consensus panel guidelines are reported in this review with the inherent limitations of this technique and best practice experiences.

“…Dies ist offenbar dann besonders relevant, wenn eine Leber-CT nur in einer Phase (in unserer Studie in einer frühen portalvenösen Phase) vorliegt. Wie gezeigt werden konnte, ist die Erkennung maligner, aber auch benigner Läsionen in der Leber-CT in verschiedenen Phasen unterschiedlich [19]. Da Lebermetastasen von Bronchialkarzinomen hypovasku-larisiert zur Darstellung kommen [19] [20 -23].…”

“…Wie gezeigt werden konnte, ist die Erkennung maligner, aber auch benigner Läsionen in der Leber-CT in verschiedenen Phasen unterschiedlich [19]. Da Lebermetastasen von Bronchialkarzinomen hypovasku-larisiert zur Darstellung kommen [19] [20 -23]. Vor allem bei isoechogenen oder echoreichen Metastasen, wie wir sie auch beim Bronchialkarzinom finden [24], oder bei kleinen Metastasen (< 1 cm) kann durch den Einsatz von Kontrastmittel die Sensitivität des US im Nachweis der Metastasen deutlich gesteigert werden [21].…”

The study demonstrates that a complementary US of the liver in patients with lung cancer may reveal information relevant for treatment. Therefore, liver US may play an important role in the staging of lung cancer. When equivocal small liver lesions are detected with CT, a complementary US examination may help to diagnose these lesions or detect metastases not visible on the single-phase staging CT of the liver.

Der Wert unterschiedlicher Spiral-CT-Phasen in der Suche nach Lebermetastasen

Abstract: For detection of liver metastases with spiral CT, contrast series seem to be sufficient. For tumors likely to seed hypervascular metastases, HAP scans should be applied in addition to the PVP.
