1. 兒童 MRI 的特殊性 磁共振成像（MRI）作為一種非侵入性的影像檢查技術，在兒童醫療領域扮演著重要角色。然而，兒童 MRI 與成人 MRI 存在顯著差異，這些差異不僅體現在生理結構上，更涉及心理與行為層面。 1.1 兒童與成人 MRI 的差異 兒童的生理結構與成人不同，尤其是器官大小、組織密度以及代謝速率。例如，兒童的腦部含水量較高，這使得 MRI 影像的解讀需要特別調整參數。此外，兒童的呼吸與心跳速率較快，容易導致影像模糊，因此需要更快的掃描技術。 香港大學醫學院的研究指出，兒童 MRI 的影像解析度需達到 1.5T 以上，才能確保診斷的準確性。而成人則可以根據病情選擇 1.5T 或 3T 的設備。這種差異使得兒童 MRI 的技術要求更高。 1.2 兒童 MRI 的挑戰：移動、恐懼 兒童在 MRI 檢查過程中容易因恐懼或不安而移動，這會嚴重影響影像品質。根據香港兒童醫院的統計，約有 60% 的 5 歲以下兒童在 MRI 檢查中需要鎮靜或麻醉。恐懼感主要來自於機器的噪音、封閉的空間以及陌生的環境。 為了解決這些問題，部分醫院引入了 技術，該技術通過優化掃描流程與環境設計，顯著降低了兒童的不適感。 1.3 鎮靜或麻醉的必要性 對於無法配合的兒童，鎮靜或麻醉是確保檢查順利進行的必要手段。然而，這也帶來了額外的風險，例如呼吸抑制或過敏反應。香港衛生署的數據顯示，兒童 MRI 中使用鎮靜劑的併發症發生率約為 0.5%，雖然比例不高，但仍需謹慎評估。 因此，專業的醫療團隊需根據兒童的年齡、健康狀況以及檢查部位，制定個性化的鎮靜方案。 2. 兒童 MRI 的掃描技術 為了解決兒童 MRI…
