Abstract:
Objective To prospectively study the sensitivity and specificity of 99m Tc Methoxyisobutyl Isonitrile( 99m Tc MIBI) scintimammorgaphy in the detection of both primary breast cancer and axillary lymph node metastasis. Methods Eighty four consecutive women suspicious of breast cancer under clinical examination were checked by the scintimammorgaphy of planar prone imaging in three planar views(5～8?min/view). The entire breast and ipsilateral axillary region were included in the field of view. Biopsy of resectional breast and lymph node were performed within 10 days after scintimammography. Results There were 51 primary breast cancer(7 different histologic types) and 33 benign breast lesion(4 histologic types) in this series. The sensitivity of scintimammography for detecting primary breast cancer was 90.20%(46/51) and the specificity was 93.93%(31/33). Metastatic axillary lymph nodes were seen in 25 of the 51 patients. The sensitivity of scintimammography to detect metastatic lymph node was 84.0%(21/25) and the specificlty was 88.46%(23/26). Conclusions The results of this study indicate that the scintimammography has high diagnosis rate in detecting breast cancer and axillary lymph node metastasis.
