# SNOMED CT 連結
<a name="ontology-linking-snomed"></a>

 使用 **InferSNOMEDCT** 偵測醫療實體，並將其連結至 2022 年 3 年 Systematized Nomenclature of Medicine， clinical Terms (SNOMED CT) 版本的概念。SNOMED CT 為您提供醫療概念的完整詞彙，包括醫療條件和結構、醫療測試、治療和程序。若要進一步了解 SNOMED CT，請造訪 [SNOMED CT](https://www.snomed.org/value-of-snomedct)。

對於每個偵測到的醫療實體，Amazon Comprehend Medical 會列出與醫療概念相關的前五個 SNOMED CT 概念 IDs 和描述，以及可信度分數，以指出模型在預測中的可信度。SNOMED CT 概念 IDs 會以可信度的遞減順序和可信度分數列出。然後，當您將 SNOMED CT 概念 IDs 與 SNOMED CT 多階層搭配使用時，即可使用 SNOMED CT 概念 ID 來建構患者臨床資料以進行醫療編碼、報告或臨床分析。

**InferSNOMEDCT** 可供美國客戶使用。如需其他國家/地區 SNOMED CT 的資訊，以及 SNOMED CT 授權的資訊，請參閱 [SNOMED CT](https://www.snomed.org/value-of-snomedct)。
