Abstract:
Objective To observe the value of ultrashort echo time(UTE)-MRI for evaluating pulmonary nodules.Methods Totally 58 patients with pulmonary nodules detected with CT were prospectively enrolled,and UTE-MRI was performed.Taken CT as the referent standard,the value of UTE-MRI for evaluating the diameter,composition,lung imaging reporting and data system(Lung-RADS)type and radiographic signs of pulmonary nodules was analyzed.Results CT detected 66 pulmonary nodules with a diameter of(11.60±5.20)mm in 58 patients,including 29 solid nodules,24 partially solid nodules and 13 ground-glass nodules.There were 14 Lung-RADS type 2,12 type 3,12 type 4A,11 type 4B and 17 type 4X lung nodules,among which 12 were found with lobulated sign,and 14 were found with spiculated sign.UTE-MRI detected 63 nodules with a diameter of(11.34±4.82)mm,including 25 solid nodules,28 partially solid nodules and 10 ground-glass nodules.There were 12 Lung-RADS type 2,12 type 3,12 type 4A,11 type 4B and 16 type 4X lung nodules.Among which 10 nodules were found with lobulated sign and 11 were found with spiculated sign.No significant difference of the measured diameters of lung nodules was found between UTE-MRI and CT(P=0.803),and the results of UTE-MRI and CT had good correlation and consistency(rs=0.953,ICC=0.946),which also had good consistency for assessing nodule composition and Lung-RADS type(Kappa=0.871,0.960).Meanwhile,no significant difference of the display rates of lobulated nor spiculated signs was noticed between UTE-MRI and CT(both P>0.05).Conclusion UTE-MRI was helpful for evaluating pulmonary nodules,with efficacy comparable to CT.
