【摘要】Objective The aim of the study was to evaluate the reliability of whole-body MRI(WBMRI)in detecting osseous metastases.Methods Thirty patients verified with malignant tumor by histology were enrolled.All
the
patients
a
underwent two
WB-MRI week
and
bone
scintigraphy(BS)with interval.Clinical
information,conventional MRI and CT images,and follow-up data were collected as gold standard for the diagnosis of bone metastases.The data of 30 patients and 270 segments as study unit respectively were analyzed.The sensitivity and specificity between WB-MRI and BS were compared with McNemar test.Resuits Bone metastases were confirmed in 27 of 30 patients by gold standard.Twenty-five patients with bone metastases were detected by WB-MRI and no false-positive cases.Twenty-seven patients with bone metastases were Nund by BS but having two false-positive oases.With patients as study unit,the diagnostic sensitivity of WB-MRI and BS were both 92.6%(25/27)and the specificity were 100%(3/3)and 33.3%(1/3),respectively.The area under ROC
curve
of
WB-MRI
and
BS
were
0.9630
and
0.6296,respectively(P>0.05).With segments as study unit,119 bone
