F-DOPA PET/CT but not Ga-DOTA-TOC PET/CT revealed the cause of ectopic Cushing syndrome in a 61-year-old man. The patient presented with rapid weight gain, swollen legs, and sleep disturbances. Plasma potassium level was 2.7 mM (reference range, 3.3-4.9 mM), 24-hour urinary cortisol ...
Diagnostic evaluation with the 18-F-L-3,4-dihydroxyphenylalanine [18F]-DOPA PET scan has been shown to have moderate-good sensitivity for diagnosis of a focal lesion but almost 100% accuracy in localizing a detected lesion. The finding of a focal lesion can change surgical approach, decrease ...
[11C-]缬氨酸和DL-11C-色氨酸, 他们能快速聚集在肿瘤病灶处, 并且清除速度快, 静脉注射这些显像剂后几乎可以立即进行PET显像. 之后, 逐渐发展有其他的正电子药物用于诊断胰腺肿瘤, 诸如11C-蛋氨酸、氮[13N]-L-谷氨酸、14C-酪氨酸、氧[15O]-水、13N-氨水、11C-5-羟色氨酸、11C-L-DOPA、18F-FET[17]以及...
So, after the 100 bagging iterations, we were able to rank the predictions for each scan according to the proportion of the respective votes received. The final RVM class assigned to each FDG PET scan was defined by the prediction that received the most votes, i.e. the most often ...
The corresponding questions in the survey had a note saying “PET/CT in planning position, with immobilization devices and a technician/RadOnc physically present during the scan.” However, we suppose that some participants could have interpreted “planning PET-CT” as referring to examinations done...
Diagnosis and Localization of Focal Congenital Hyperinsulinism by 18F-Fluorodopa PET Scan To assess the accuracy of 18F-fluoro- l-dihydroxyphenylalanine ([ 18F]-DOPA) PET scans to diagnose focal versus diffuse disease and to localize focal lesio... OT Hardy,M Hernandez-Pampaloni,JR Saffer,......
