本研究使用電子核磁共振系統量測中低場核磁共振系統應用於肝臟(Liver)樣品之縱向鬆弛時間T_1(Longitudinal relaxation time)與橫向鬆弛時間T_2(Transverse relaxation time)之特性。 利用電子核磁共振系統的Carr-Purcell-Meiboom-Gill(CPMG序列)、 Spin echo序列模式進行T_1 T_2之數據量測,並透過統計學的方法來討論T_1 T_2是否不因組織相同或相異而產生特定之結果。 研究取用微量0.075g~0.130g的肝臟樣品,經實驗測量,縱向鬆弛時間T_1對比於正常組織在腫瘤組織上具有較高的數值,具有明顯的生物特性,與過去本實驗室進行各種腫瘤組織之T_1量測特性相同。 研究中也以統計學中T-Test與ROC Curve兩種方式分析其數據,而橫向鬆弛時間T_2的研究部份,其不具可辨識之生物特性。
