乳腺专用伽玛显像（BSGI）是一种在传统伽玛照相机的基础上进行了优化的核医学显像技术，配置有高分辨率数字探测器，内置3072块晶体和48个光电倍增管。探测器的视野（FOV）为15 cm×20 cm，空间分辨率为3 mm，能探查到直径仅为2~3 mm的微小病灶，对亚厘米或不能触及的病灶有很高的应用价值，且不受乳腺致密组织、植入假体及术后瘢痕等因素的影响，对乳腺癌诊断的灵敏度较高。BSGI被称为小视野和高分辨率乳腺专用伽玛照相机。

Breast-Specific Gamma Imaging(BSGI)is an improved and optimizing nuclear medicine breast imaging technique on the basis of traditional gamma camera. It uses a high resolution, smal field-of-view scintil a detector. The detector is designed with 3 073 individual detector crystals and 48 position-sensitive photomultiplier tubes. The FOV of detector is 15 cm×20 cm, and optimal system resolution for breast imaging is 3 mm, can detect the diameter of only 2~3 mm smal lesions. BSGI has better sensitivity in detecting subcentimetre or nonpalpable breast cancer. The sensitivity for the diagnosis of breast cancer is high, not influenced by the density of the breast tissue, implants, architectural distortion or scars from prior surgery or radiation. So it is cal ed a high resolution, smal field-of-view breast-specific gamma camera.
