Abstract
The dissimilarities in spin-lattice relaxation time (T1) of water proton from one tumor to the other is due to the yield of hypoxic fraction in the tumor. The yield of higher relaxation time (T1) in the KHT tumor compared to the RIF-1 tumor as a function of growth is due to the hypoxic fraction of the tumor. The hypoxic fraction in the tumor is also responsible for the P-31 spectral parameter changes.
摘要
一种肿瘤与另一种肿瘤中水质子的自旋晶格弛豫时间（T1）的差异是由于肿瘤中缺氧部分的产生。与RIF-1肿瘤相比，KHT肿瘤中较高弛豫时间（T1）的产生随生长而变化，这是由于肿瘤的缺氧部分。肿瘤中的缺氧部分也是P-31光谱参数变化的原因。
