【摘要】 18 F FDG(18F 氟脱氧葡萄糖 )PET(正电子发射型计算断层显像 )是反映恶性肿瘤代谢特征的一种无创性的功能显像方法 ,在绝大多数肿瘤中均得到广泛应用。本文通过对国内外乳腺癌18F FDGPET显像的文章进行全面综合分析 ,旨在探讨18F FDGPET显像在乳腺癌中的应用原理及其临床应用价值。与传统影像学相比 ,18F FDGPET显像能够更为准确地发现原发性乳腺癌远处转移和局部复发 ,可以在治疗早期及时评价化疗疗效以指导临床治疗。对于原发性乳腺癌的诊断 ,PET显像不作为首选检查 ,但对于临床检查或常规影像检查难以进行或无明确结论的病人 ,PET显像可以作为其乳腺肿块定性诊断的最佳选择。更多还原

【Abstract】 Positron emission tomography (PET) with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose ( 18F-FDG) representing a noninvasive functional imaging modality that is based on metabolic characteristics of malignant tumors is well applied to most tumors.This article reviewed the literature about 18F-FDG PET imaging in breast cancer aiming to investigate the clinical value and principle of 18F-FDG PET imaging in primary breast cancer.In contrast to conventional imaging methods, 18F-FDG PET imaging is more accurate for the staging of distant metastases and recurrences,enables early assessment of treatment response in patients undergoing primary chemotherapy. 18F-FDG PET imaging isn’t the first choice in the diagnosis of primary breast cancer,but it is more suitable to those people who are unwilling to or ambiguous by clinical examination and conventional technologies.更多还原
