本期“重点号”中,陈琬琦等[11]回顾性分析行18F-FDG 全身PET/CT显像的0~3岁婴幼儿共59例,结果显示全剂量组(21例;按体质量3.70 MBq/kg)和半剂量组(38例;按体质量1.85 MBq/kg)患儿肝脏SNR分别为29.5(25.3,39.9)和25.8(22.0,30.4), 但差异无...
一项临床研究对19例食管癌患者在术前进行了超声内镜、CT、PET/MR和低剂量PET/CT检查,并对各种检查方法在分期中的价值进行了对比分析(表3) [ 44] ,结果显示超声内镜在T分期方面准确性最高,PET/MR在N分期方面准确性最高,非增强PET/CT(双排CT)没有进行T分期研究;对于N分期,PET/MR、超声内镜、PET/CT及CT的准...
PET/CT in Neuroendocrine Tumors: Evaluation of Receptor Status and Metabolism In-111 Octreoscan is considered the gold standard for imaging of neuroendocrine tumors (NET). However, in the absence of morphologic imaging correlation, t... V Prasad,V Ambrosini,A Alavi,... - 《Pet Clinics》 ...
对于大多数实体瘤(如NSCLC、黑色素瘤等),推荐应用实体瘤免疫治疗PET评价标准(immune PET response criteria in solid tumors, iPERCIST)评价(表1);淋巴瘤推荐应用LYRIC评价(表2)。 五、总结 综上所述, F-FDG PET/CT在评价肿瘤的免疫治疗反应、判读免疫相关不良反应等方面,较基于传统影像技术的RECIST标准具有较大...
Doctor also use PET scans to check for brain conditions, such as: Alzheimer’s disease Parkinson’s disease Huntington’s disease Seizures Strokes Tumors PET Scan vs. CT Scan CT scans use X-rays to take images of the inside of your body, including your bones, blood vessels, and soft tissu...
For each pair, after CT- based registration of the PET images, the two PET datasets were subtracted. A biparametric graph of subtracted voxel values versus voxel values in the first scan was obtained. A model- based analysis of this graph was used to identify the tumor voxels in which ...
In pediatric practice, F-FDG PET/CT is now considered standard of care for the diagnosis, staging, and posttreatment response assessment for an increasing number of pediatric malignancies. The relative rarity of pediatric tumors, availab... LJ States,SD Voss 被引量: 0发表: 2019年 Clinical and...
