Abstract:
Objective To investigate the diagnotic value of tumor positive delay tomogram imaging with 99Tcm-methoxyisobutylisonitrile (MIBI) for pulmonary neoplasm.
Methods Twenty-eight cases pulmonary neoplasms traded by 99Tcm-MIBI imaging, then performed tomogram imaging after 1h.By the uptake ratio value exceeding 1.31 between pulmonary neoplasm(T)and normal tissue on the opposite side or vicinity tissue(N), benign or malignant was diagnosted.
Results The malignant pulmonary neoplasm had abnormal high uptake, but benign pulmonary neoplasm had light uptake.The sensitivity and specificity of 99Tcm-MIBI imaging for the malignant pulmonary neoplasm were 76.9% and 86.7% respectively, the false positive and false negative rate were 13.3% and 23.1% respectively.
Conclusions Tumor positive delay tomogram imaging with 99Tcm-MIBI for pulmonary neoplasm is an important detection in differentiating benign and malignant, it has high sensitivity, specificity, picture quanlity and no wound again.
