本研究的目的是比较使用高分辨率乳腺特异性伽马相机和磁共振成像 (MRI) 对乳腺检查结果不确定的患者进行乳腺特异性伽马成像 (BSGI) 的敏感性和特异性。纳入的 23 名女性的乳房检查结果不确定，需要进行 BSGI 和 MRI 检查，因为解读放射科医生或转诊医生认为有必要。 MRI 在 GE 1.5T 扫描仪上进行，BSGI 在 Dilon 高分辨率乳腺特异性伽马相机上进行。所有影像学检查结果均与病理诊断相关。该研究评估了三十三个不确定的病变。共有九种经病理证实的癌症。 BSGI 和 MRI 之间癌症检测的敏感性没有统计学上的显着差异。 BSGI 表现出比 MRI 更高的特异性，分别为 71% 和 25%。 BSGI 在检测乳腺癌方面与 MRI 具有相同的敏感性和更高的特异性。
The purpose of this study was to compare the sensitivity and specificity of breast-specific gamma imaging (BSGI) using a high-resolution breast-specific gamma camera and magnetic resonance imaging (MRI) in patients with indeterminate breast findings. Twenty-three women with an indeterminate breast finding that required BSGI and MRI as deemed necessary by the interpreting radiologist or referring physician were included. MRI was performed on a GE 1.5T scanner and BSGI was performed on a Dilon high-resolution breast-specific gamma camera. All imaging findings were correlated with pathologic diagnosis. Thirty-three indeterminate lesions were evaluated in the study. There were a total of nine pathologically confirmed cancers. There was no statistically significant difference in sensitivity of cancer detection between BSGI and MRI. BSGI demonstrated a greater specificity than MRI, 71% and 25%, respectively. BSGI has equal sensitivity and greater specificity than MRI for the detection of breast cancer.
