Abstract:Objective To evaluate the value of 99 Tc m MIBI imaging in detection of axillary lymph node involvement and to assess imaging characteristics of the lesions Methods 18 patients with pathologically confirmed breast cancer underwent 99 Tc m MIBI scintigraphy of the breast An additional 14 females with no palpable breast abnormalities were also studied using 99 Tc m MIBI The early and delay images were acquired at 5, 30 and 60 min after injection of 1 110 MBq 99 Tc m MIBI intravenously Three planar views, right and left lateral prone and anterior supine views were obtained, the entire breast and ipsilateral axillary region were included in the field of view Radical mastectomy and lymph node clearance were performed on all 18 patients with confirmed breast cancer within 1 week, and the excised lymph nodes were histopathologically examined Results Metastatic axillary lymph node involvement was seen in 11 patients The sensitivity of scintimammography to detect metastatic lymph node was 78 6% The size and degree of axillary lymph node involvement greatly influenced their imaging characteristics Conclusions 99 Tc m MIBI scintigraphy of axillary lymph node is an effective means of detecting and localizing axillary lymph node involvement, and it would be very helpful to working out surgery program and predicting the prognosis for the patients
