半剂量99mTc-MIBI双时相断层显像在乳腺肿块诊断中的价值
Diagnostic value of half the radiation dose double-phase 99mTc-MIBI tomographic imaging in breast lesions
摘要
Abstract
Objective To study the diagnostic value of half the radiationdose double-phase 99mTc-MIBI tomographic imaging in breast lesions.Methods A total of 220 patients with breast lesions were randomly divided into half the radiation dose group (99mTc-MIBI injected dose was 370 MBq) and the conventional dose group(99mTc-MIBI injected dose was 740MBq).All patients underwent double-phase 99mTc-MIBI tomographic imaging in breast lesions.The early phase and delayed phase of radioactivity ratio (T/NT) of breast lesions were calculated separately,and the diagnostic efficiency of breast cancer was compared.Results The early phase T/NT in half the radiation dose group of patients with benign lesions was higher than the delay phase T/NT (P ＜ 0.05),and the early phase T/NT in patients with malignant lesions was higher than that in patients with benign lesions (P ＜ 0.05).the early phase T/NT in the conventional dose group of patients with benign lesions was higher than the delay phase T/NT (P ＜ 0.05),and the early phase T/NT in patients with malignant lesions was higher than that in patients with benign lesions (P ＜ 0.05).T/NT comparative differences had no statistical significance in two groups between the early phase and the delayed phase (P ＞ 0.05).The sensitivity,specificity and accuracy of breast cancer had no statistically significant difference in two groups (P ＞ 0.05).Conclusion Half the radiation dose double-phase 99mTc-MIBI tomographic imaging in breast lesions has good image quality,and it doesnt affect the clinical diagnosis and reduce half of radiation dose.关键词
