Abstrakt		The purpose of this prospective study was to evaluate the efficacy of Color Power Angio imaging and Color Doppler for identification of vascularisation in patients with different liver tumors. Patients and methods. In 55 patients with liver tumors (male 36, female 19, av. age 65.5 years, SD +- 18, span 37-87 years; 15 patients with hepatocellular carcinoma, 26 patients with metastatic liver tumors and 14 patients with benign lesions) ultrasound investigations were performed. In all patients with malignant tumors the lesions were confirmed histologically. The sonographic examinations, Doppler sonography, Color Power Angio imaging and flow calculations were carried out on ATL HDI R 3000 Ultrasound System, ultrasound device equipped with a ultrasound probe of 2-4 Mhz frequency range and 2.5 MHz Doppler frequency. Results. Doppler vascularsignals were detected in 38/55 (69%) patients; Color Power Angio imaging detected vascularisation in 50/55 (90.9%) patients, p < 0.01. Presence and distribution of Color Doppler and Color Power Angio signals did not significantly differ in benign and malignant lesions. Conclusions. These results indicate that both imaging modalities are useful for ascertainment of liver tumor vascularity. Color Power Angio imaging is more sensitive than Color Doppler in identifying vascular signals in liver tumors and benign lesions of the liver.
Izvleček		Izhodišča. Cilj prospektivne raziskave je bil ugotoviti učinkovitost barvnega doplerja pri oceni ožiljenosti različnih jetrnih tumorjev. Preiskovanci in metode. Pri 55 bolnikih z jetrnimi tumorji (36 moških, 19 žensk, povp. starost 65,5 leta, SD +- 18, v razponu 37-87 let; 15 bolnikov z jetrnoceličnim žleznim rakom, 26 bolnikov z jetrnimi zasevki in 14 bolnikov z benignimi tumorji) smo opravili ultrazvočne preiskave. Pri vseh bolnikih z zločestimi tumorji smo jetrne spremembe potrdili patohistološko. Ultrazvočne preiskave, doplerjeve preiskave in barvni, energijski žilni prikaz in meritve pretokov smo opravili z ATL HDI 3000 ultrazvočnim instrumentom, opremljenim s tipalom frekvence 2-4 Mhz in 2,5 MHz doplerjevo frekvenco. Rezultati. Doplerske žilne signale smo ugotovilil pri 38/55 (69%) bolnikov; z barvnim, energijskim žilnim prikazom smo ugotovili ožiljenost pri 50/55 (90,9%) bolnikov, p < 0,01. Prisotnost in razporeditev doplerjevih signalov in barvnega energijskega žilnega prikaza se nista značilno raziskovala pri zločestih jetrnih tumorjih in benignih spremembah. Zaključki. Ti rezultati potrjujejo, da sta obe slikovni metodi učinkoviti pri ugotavljanju ožiljenosti jetrnih tumorjev. Barvni energijeski žilni prikaz je bolj občutljiv pri zaznavanju žil pri zločestih jetrnih tumorjih in benignih jetrnih spremembah kot barvni dopler.
