1) ionic X-ray contrast agent
离子型X线造影剂
1.
Iothalamic acid, an ionic X-ray contrast agent was synthesized from monomethyl 5-nitroisophthlate and methylamine by amidation to give 3-nitro-5-[(methylamino)carbonyl]benzoic acid, which was subjected to catalytic hydrogenation and iodination to afford 3-amino-2,4,6-triiodo-5-[(methylamino)carbonyl]benzoic acid, followed by acetylation with acetic anhydride with an overall yield of about 80%.
5-硝基-1,3-苯二甲酸单甲酯和40%甲胺水溶液经酰胺化反应得到3-硝基-5-[(甲胺基)羰基]苯甲酸,再经Pd/C催化氢化还原和氯化碘碘代得到3-氨基-2,4,6-三碘-5-[(甲胺基)羰基]苯甲酸,最后经乙酰化反应制得离子型X线造影剂碘他拉酸,总收率约80%。

6) Radiography
[英][,reɪdi'ɔɡrəfi] [美]['redɪ'ɑgrəfɪ]
X线钡剂造影
补充资料：脑室造影
脑室造影
X线检查方法之一。将对比剂直接引入脑室系统内，以显示脑室的形态、位置的检查方法。对比剂可采用气体或水溶性碘剂，选择特定部位经颅骨穿刺或钻孔导入。该检查属有创性，已为CT、MRI等取代。
