胃祕素值高，IN-111核子醫學造影是什麼? - 藥品

今天到北榮看腸胃科，之前就已經得知抽血檢查的胃泌素比較高（醫生說法）
所以轉介給另一個一樣腸胃科教授看診，結果教授問我要不要自費做核醫的檢查
只看到檢查項目那攔寫著IN-111 OCTREOSCAN (SEFLF-PAY)
請問那是什麼樣子的檢查呢?核醫部的人員只說是屬於內分泌類的檢查
那麼醫師要我做這檢查的目的是檢查什麼呢?
畢竟檢查這個要自費2萬多，且醫師說也可能檢查了也沒怎樣
去年十二月住院，主要是因十二指腸潰瘍血管裸露，跟缺鐵性貧血
也做了胃鏡／大腸鏡／抽血／超音波等檢查，可是造成長期潰瘍的原因不明
Nexium也都吃很長一段時間，無間斷過，卻依然時常反覆發病掛急診
每每都是肚子上腹以左邊後腰那邊痛，住院頻繁到找不到血管打點滴了
也手術過三次
The 14y/o boy with past historyof 1. duednum stenosis s/p op three times.
2. A loop syndrome s/p reversed operation with gstrrhaphy ， small intestine resection with anastomosis and pyloroplasty on 93-7-8 was admitted to our ward due to chest pain and vomiting several times.
Lab data revealed leukocytosis with neutrophil predominant. He didn’t have URI symptoms and Diarrhea.
The chest pain was retrosternal dull pain without radiation and the ECG revealed no
obvious abomity. The vomitus was non-bilius food contant. Poor appetite and poor activity were decreased.
The impression was GERD. After admission ， pediatric CV was consulted and
suggested doing GERD evaluation.
24hrs esophageal PH moniter was arranged on 93-7-28and
revealed negative finding.
Esophgogram was arrangedand revealed no obvious esophageal stricture or abnormity. Under stable condition ， he was MBD on 93-7-31 and suggested to receive OPD follow up.
所以想請教相關的專業人員替小弟我解答，感謝！
不然小弟從小以來就飽受腸胃病之苦至今，實在痛苦
主要回答IN-111的部分就好，謝謝！
