Abstract:
Objective To compare and analyze the application value of brain black blood technology three-dimensional BrainVIEW(3D-BrainVIEW)and conventional three-dimensional turbo field echo T1 weighted imaging(3D-TFE T1WI)in brain metastases of lung cancer.Methods A total of 60 patients with pathologically confirmed lung cancer were selected.All patients underwent brain enhanced MRI using 3D-BrainVIEW and 3D-TFE T1WI.The signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the two groups were compared and analyzed,respectively.The diagnostic efficacy(including number,size,and location)of the two groups of images in detecting brain metastases was evaluated by two experienced radiologists via double-blind method.Results The diagnostic consistency between the two radiologists was excellent[intraclass correlation coefficient(ICC)=0.998,P<0.001].There were significant differences in SNR,CNR,and the number and location of brain metastases between 3D-BrainVIEW sequence and 3D-TFE T1WI sequence(P<0.05),and 3D-BrainVIEW sequence was significantly superior to 3D-TFE T1WI sequence.In addition,the number of brain metastases detected by 3D-Brain VIEW sequence was significantly higher than that detected by 3D-TFE T1WI sequence in lesions with minimum diameter(Dmin)<5 mm(P<0.001).There was no difference in the number of lesions detected by the two sequences in lesions with Dmin>5 mm(P>0.05).Conclusion The SNR and CNR of 3D-Brain VIEW enhanced scan images are significantly higher than those of 3D-TFE T1WI,which has higher detection efficiency for lung cancer brain metastases,and can effectively reduce misdiagnosis caused by microvascular enhance-ment,which has high clinical application value.
