Application Value of Magnetic Resonance Liver Rapid Volume Imaging Technology and Enhanced CT in Nodular Lesions of Liver

Objective To explore the value of applying contrast MRI-LAVA sequence and enhanced CT in the diagnosis of nodular lesions of the liver.Methods 78 patients with hepatic nodular lesions were selected,all of them were diagnosed by MRI-LAVA sequence and enhanced CT.The diagnostic accuracy,sensitivity,specificity and accuracy of the two diagnostic methods were compared.Results According to the pathological diagnosis results,91 lesions were diagnosed,including 24 lesions with a diameter larger than 3 cm and 67 lesions with a diameter less than 3 cm.There was no significant difference in the diagnostic accuracy between MRI-LAVA sequence diagnosis and enhanced CT diagnosis in lesions with a diameter larger than 3 cm(P>0.05),while in the diagnosis of lesions with a diameter less than 3 cm,the diagnostic accuracy of MRILAVA sequence was higher than that of enhanced CT(P<0.05).Meanwhile,there was no significant difference in specificity between MRI-LAVA sequence diagnosis and enhanced CT diagnosis(P>0.05).However,the sensitivity and accuracy of MRI-LAVA sequence diagnosis were higher than those of enhanced CT diagnosis(P<0.05).Conclusion The diagnostic value of MRI-LAVA sequence technique in nodular lesions of the liver is higher than that of enhanced CT,and it is worth popularizing MRI-LAVA sequence technique in the clinical diagnosis of nodular lesions of the liver.
