比较常见的前纵隔肿瘤有胸腺肿瘤、生殖细胞性肿瘤、淋巴瘤等。前纵隔肿瘤的临床表现依肿瘤大小、部位及良恶性的不同而异,其早期症状不典型,缺乏特异性,一般随瘤体增大才会出现胸痛、憋气等症状,所以早期诊断较困难,易误诊漏诊。笔者选取2例前纵隔占位的病例,通过分析其18F-FDG PET/CT影像学及临床特征进行鉴别诊断,归纳总结诊断思路,以提高对其诊断的准确率。 相似文献

五年来我們用水楊酸汞糊剂治疗鷄眼,茲介紹如下:处方:水楊酸汞軟膏各一份用膠布將鷄眼与周圍組織隔离,鷄眼上抹厚層的糊剂,盖上蜡紙(或贴膠布),其上放薄層棉花用繃帶包紥。如此保留3—4天,然后除去绷带,行苏打足浴20—30分钟,等5天才重复上述疗法一次,兩次(很少需3次)为一疗程。 相似文献

Hepatocellular carcinoma (HCC) is one of the most lethal tumors and has high malignancy and low survival. Generally, the glucose metabolism in malignant tumors is significantly different from normal tissues, which show high uptake. However, it varies greatly in HCC. Low glucose metabolism is often observed in well- and moderately differentiated HCC. Furthermore, glycolysis has been widely confirmed to be a nonspecific biological phenomenon in malignant tumors, including HCC, by positron emission tomography (PET) combined with computed tomography using 18-fluorine-fluorodeoxyglucose (a glucose analogue). However, to determine the value of PET and develop new effective drugs and molecular probes, we need to comprehensively understand how hepatocellular cancer cells use glucose to supply energy. In this article, we reviewed and summarized the glycometabolism characteristics of HCC and their application in PET. 相似文献

肺淋巴瘤的影像学表现多种多样,需结合病变CT特征、FDG浓聚程度、其他脏器侵犯情况以及实验室检查等进行综合判断。笔者选取了2例经病理确诊的肺淋巴瘤患者,分别为原发性肺淋巴瘤和继发性肺淋巴瘤,详细分析了其临床特征及18F-FDG PET/CT影像学表现,期待对临床有所帮助。 相似文献
