Zusammenfassung
Ziel: Die HTT von USKM ist bei Patienten mit Lebermetastasen verkürzt. Studien mit SonoVue™ zeigten auch bei Probanden eine verkürzte HTT. Somit hängt die HTT auch vom USKM ab. Wir untersuchten, ob die HTT von SonoVue™, Luminity™ und Levovist™ benutzt werden kann, um Patienten mit und ohne Lebermetastasen zu unterscheiden. Material und Methoden: Wir verglichen die arteriovenöse HTT von Levovist™, Sonovue™ und Luminity™ bei 20 Patienten mit Lebermetastasen und 15 Probanden. Hierfür verwendeten wir ein Acuson sequoia™. Die HTT ist die Differenz der Ankunftszeit des USKM in der A. hepatica und einer V. hepatica. Ergebnisse: Bei Levovist™ mussten 6 Patienten und 3 Probanden von der weiteren Analyse ausgeschlossen werden, da die Ankunftszeit nicht detektierbar war. Die durchschnittliche HTT bei Probanden betrug für Levovist™ 14,75 s (SD ± 2,53 s), für SonoVue™ 9,27 s (SD ± 2,41 s) und für Luminity™ 9,2 s (SD ± 2,34 s). Bei Patienten betrug die HTT für Levovist™ 9,89 s (SD ± 1,04 s) für SonoVue™ 6,28 s (SD ± 2,41 s) und für Luminity™ 6,33 s (SD ± 1,37 s). Bei einem Grenzwert von 8 s für Luminity™ und SonoVue™ ergab sich eine Sensitivität für den Ausschluss von Metastasen von 80 bzw. 75 %. Schlussfolgerung: Die durchschnittliche HTT aller USKM war bei Patienten signifikant kürzer. Levovist™ zeigte bei Probanden und Patienten eine längere HTT als Luminity™ und SonoVue™. Levovist™ zeigte die beste Separation zwischen Patienten mit Metastasen und Probanden, jedoch mussten in der angewandten Technik ein Teil der Patienten und Probanden ausgeschlossen werden. Die HTT könnte ein nützliches Instrument zum Ausschluss von Lebermetastasen sein, ist jedoch abhängig von der Art des USKM und der kontrastspezifischen Bildtechnik.
Abstract
Purpose: Liver metastases lead to a shortening of the HTT of an echo enhancer. Studies using SonoVue™ also showed a shortening of the HTT in healthy controls. Hence the HTT depends on the applied contrast agent. We examined whether the HTT of SonoVue™, Luminity™ und Levovist™ is useful to discriminate between patients with and without liver metastases. Materials and Methods: We compared the arteriovenous HTT of Levovist™, Sonovue™ und Luminity™ in 20 patients with liver metastases and in 15 controls. An Acuson Sequoia™ ultrasound system was used. The HTT results from the difference of the arrival time of the microbubbles in the hepatic artery and a hepatic vein. Results: Using Levovist™ six patients and three controls had to be excluded from further analysis. The arrival time was undetectable. The mean HTT values in healthy controls were: Levovsit™ 14.75 sec (SD ± 2.53 sec), SonoVue™ 9.27 sec (SD ± 2.41 sec) and Luminity™ 9.2 sec (SD ± 2.34 sec). In patients the mean HTT values were: Levovist™ 9.89 sec (SD ± 1.04 sec), SonoVue™ 6.28 sec (SD ± 2.41 sec) and Luminity™ 6.33 sec (SD ± 1.37 sec). Using a cut off of 8 sec for SonoVue™ and Luminity™, the sensitivity to exclude liver metastases was 75 % and 80 %. Conclusion: The mean HTT values of all contrast agents were shorter in patients. Levovist™ showed a longer HTT in patients and controls than Luminity™ and SonoVue™. Levovist™ showed the best separation between patients and controls but some patients and controls had to be excluded. The HTT could still be a useful tool to exclude liver metastases but the HTT depends on the contrast agent and the applied contrast technique.
