Application of multislice CT scan combined with 99mTC -MIBI -SPECT in the diagnosis of isolation pulmonary nodule lesions / 中国基层医药

ABSTRACT

Objective To discuss the applied value of multislice CT scan in combination with 99 MTC -MI-BI -SPECT for the diagnosis of isolated pulmonary nodule lesions.Methods 60 patients with solitary pulmonary nodules shadow in the X -ray film from July 2014 to August 2015 in our hospital were selected and detected by spiral CT scanning and 99mTC -MIBI -SPECT imaging.Scan results and pathological examination or surgery were com-pared,specificity,sensitivity and accuracy of pulmonary nodules were concluded about the method in the differential diagnosis isolation.Results The specificity,sensitivity and accuracy of multislice spiral CT scanning alone were 73.6%,78.2%,79.3% respectively;The specificity,sensitivity and accuracy of 99mTC -MIBI -SPECT imaging alone,were 82.6%,78.2%,79.3% respectively;The specificity,sensitivity and accuracy of multislice CT scan com-bined with 99mTC -MIBI -SPECT imaging were 93.3%,93.2%,93.8% respectively.The accuracy of combined detection was significantly higher than that of 99mTC -MIBI -SPECT examination(χ2 =6.783,P =0.010)or CT scan (χ2 =8.012,P =0.008).Conclusion Multislice CT scanning combined with 99mTC -MIBI -SPECT imaging has better effect in diagnosing pulmonary nodule lesions,which is superior to the method alone.The combination meth-od can obviously improve the detection rate of lung nodule lesions,which is,worthy of further promotion.
