Abstract:

Objective

To analyze the diagnostic efficacy of contrast-enhanced ultrasound(CEUS)and upper abdominal enhanced magnetic resonance(MRI)scanning in patients with hepatic hemangioma.

Methods

A total of 86 patients with hepatic hemangioma admitted from January 2021 to October 2022 were selected as subjects.The surgical pathology results of patients were used as the diagnostic gold standard to compare the diagnostic efficacy of CEUS and enhanced upper abdominal MRI plain scan for hepatic hemangioma.

Results

Among the 86 patients with hepatic hemangioma, 80 cases met by CEUS, with a diagnostic coincidence rate of 93.02%; 75 cases met by upper abdominal enhanced magnetic resonance scanning, with a diagnostic coincidence rate of 87.21%.There was no significant difference in diagnostic coincidence rate between contrast-enhanced ultrasound and upper abdominal enhanced magnetic resonance scanning(93.02% vs.87.21%, P>0.05). The positive rate of CEUS and upper abdominal enhanced magnetic resonance scanning for hepatic hemangioma with≥4 mm diameter was 90.91%(30/33)and 100.00%(33/33)respectively, with no statistically significant difference(P>0.05). The positive rates of CEUS and upper abdominal enhanced magnetic resonance scanning for hepatic hemangioma with<4 mm diameter were 94.34%(50/53)and 79.25%(42/53)respectively.The positive rate of CEUS was higher than that of upper abdominal enhanced magnetic resonance scanning(P<0.05). CEUS: The arterial stage showed spot-like and nodular centripetal enhancement without central enhancement; the portal stage showed centripetal filling, the lesion echo increased compared to the surrounding tissue; the delayed stage showed slow filling compared to the surrounding liver parenchyma.Upper abdominal enhanced magnetic resonance scanning: low density mass shadow could be seen in the liver of the patient, and the external surface of the lesion was smooth.Compared with T1, T2 and ADC images, it was found that the scope of tumor enhancement in venous stage was enlarged and expanded, and the remaining two phases showed nodular enhancement.

Conclusion

Both CEUS and contrast-enhanced magnetic resonance scanning have good diagnostic efficacy in the diagnosis of hepatic hemangioma patients, but CEUS has a relatively higher detection rate in small-diameter hepatic hemangioma.CEUS and contrast-enhanced magnetic resonance scanning in the upper abdomen can be used in the diagnosis of hepatic hemangioma clinically, which is conducive to increasing the diagnostic accuracy of hepatic hemangioma disease.
