To evaluate the value of contrast-enhanced ultrasound (CEUS) and color Doppler ultrasound in the iagnosis of primary small hepatocellular carcinoma (SHCC).
Methods:
A total of 80 primary SHCCS (diameter less than 3 cm) confirmed by imaging
cytological biopsy or surgical pathology were selected. The features of CEUS and color Doppler ultrasound were retrospectively analyzed.
Results:
On CEUS 54 lesions displayed fast in fast out pattern
16 lesions subsided slowly as fast in slow out pattern
and 8 lesions displayed slow in fast out pattern.
The sensitivity was 97.4% (75/77)
the specificity was 94.6% (70/74)
and the accuracy was 93.8% (75/80). Color Doppler ultrasound showed that 76 lesions had blood supply vessels withⅠ-Ⅱ grade. The peak systolic velocity (PSV) was (5011.9) cm/s
and resistance index (RI) was 0.70 0.10. Four lesions had unsatisfactory imaging because of deep position. The sensitivity was 91.7% (66/72)
the specificity was 83.8% (57/68)
and the accuracy was 77.5% (62/80). The two diagnostic methods could effectively display perfusion characteristics of primary SHCC.
Conclusion:
CEUS and color Doppler ultrasound can effectively predict primary SHCC
with significance and application value in clinic.
