Description

A comparative study, on 251 patients, between CT, Octoson and conventional ultrasound, established that CT (with angio-CT) had the highest rate of sensitivity (95.86%). The Octoson examination had a higher sensitivity (92.58%) than the conventional ultrasonic examination (82.64%). This result is achieved because superficial and subdiaphragmatic metastases, which lie in the depth of the liver, are better presented by the Octoson than with a mechanical sector scanner. Suberficial metastases need to be presented with a water-path transducer for superficial lesions and subdiaphragmatic metastases with a wide range focus transducer. These areas can also be accurately shown on scanners with a dynamic transducer. The specifity of these three models lies between 90 and 96%. (orig.)

Abstract (German)

In einer Vergleichsstudie Computertomographie/Octoson/konventioneller Ultraschall bei 251 Patienten ergibt sich fuer die Computertomographie (mit Angio-CT) der hoechste Wert der Sensitivitaet (95,86%). Die Octoson-Untersuchung hat eine hoehere Sensitivitaet (92,58%) als die konventionelle Ultraschalluntersuchung (82,64%). Dies ist bedingt durch die bessere Darstellung oberflaechlicher sowie subdiaphragmal in der Tiefe der Leber gelegener Metastasen am Octoson als mit den mechanischen Sektorscannern. Oberflaechliche Metastasen muessen mit einem Nahbereichsschallkopf, subdiaphragmal in der Tiefe gelegene Raumforderungen mit einem Langfokusschallkopf dargestellt werden. Auch mit Geraeten, die einen dynamischen Fokus haben, koennen diese Bereiche gut dargestellt werden. Die Spezifitaeten der drei Methoden liegen zwischen 90 und 96%. (orig.)
