正子攝影報告判讀？

醫生您好上次做的正子攝影報告出來了有些疑問想問醫生報告如下The whole body study revealed increased uptake of radioactivity involving right nasopharynx(suv 3.1, score 1-2) and right upper neck node (suv 2.7 ,score 1-2) .There was no other abnormal measurable lesion in other parts of the body.In addition ,subpleural nodule was found by coregistered CT in right middle lung(low-dose, free breathing)without measurable FDG uptake (score 1-2).Impression
1、Mild focal uptake over right nasopharynx and small upper neck node, more in favor of inflammation or benign lymphoid hyperplasia.
2、Right middle lung subpleural nodule without measurable uptake.post-inflammatory change may show this picture.3.No other abnormal focal uptake lesion in the scanned range.Comment :1.FDG PET scan might demonstrate a false negative resule if tumor size below 0.6 cm or non-FDG-avid.2.Score 0=normal ;score 1=benign lesion; score 2=equivocal lesion; score 3=possible malignancy ; score 4=high probability of malignancy看了報告的敘述，感覺是蠻正面的，但是我比較擔心的是，nasopharynx (suv 3.1, score 1-2) and right upper neck node (suv 2.7 ,score 1-2) .這兩個顯影的suv有點高，查了相關資料，suv<2，良性發炎居多，suv>2.5惡性居多。
查了很多資料都是以2.5為基準。
我有詢問過幫我做正子的醫生，他說這樣還算低。
我不知道是我太悲觀，還是醫生太樂觀，還是2.5這個標準根本沒有參考價值(但又幾乎所有的資料都寫2.5)。
字數有點多 再麻煩醫生了
