ABSTRACT
OBJECTIVE:
To investigate the value of real-time harmonic contrast-enhanced ultrasound (CEUS) in the diagnosis of atypical liver abscesses.METHODS:
We used Technos DU8 system with CEUS technique to examine 32 patients with suspected liver masses. Mechanical index was set at 0.08- 0.11. The contrast agent SonoVue was injected as a bolus (2.4 ml, < 5s) in the antecubital vein.RESULTS:
A total of 36 lesions were studied in 32 patients, including 30 patients with single nodule and 2 patients with multiple nodules. All lesions with liver abscess were confirmed by biopsy. The whole-enhanced pattern in all lesions was clearly displayed in the arterial phase after the administration of SonoVue. The mean time of the beginning enhancement was (14.48 +/- 3.62) s, the mean peak enhancement time was (22.92 +/- 4.35) s, and the mean time of hypoechoic appearance of lesion was (80.30 +/- 35.30) s. The lesions with hypoechoic pattern (37.5%, 12/32) and isoechoic pattern (62.5%, 20/32) in the portal phase were detected by CEUS. The characteristic sign with honeycomb pattern on CEUS was shown in 30 (93.8%) liver abscess lesions.CONCLUSION:
CEUS is valuable in the diagnosis of atypical liver abscesses.
