CT vs MR

qzhongqing

Advantages of MR compared with CT:
1, excellent differentiation of soft tissue
2, images can be acquired in any orientation
3, does not use ionizing radiation
4, contrast mediums used in MR have fewer side effects
Disadvantages of MR compared with CT:
1, Scan times typically much longer
2, Spatial resolution much less
3, Sensitive to environmentals (magnetic field influences)
4, Strong magnetic field precludes some patients from being examined with MR: pacemakers, stents, prosthesis, etc.
5, Costs more
6,Is very confining, intimidating to patients suffering claustrophobia
7Not suitable for bone studies

　相比的优势:
　　1、优秀的分化的软组织
　　二、影像可以在任何方向
　　三、不使用电离辐射
　　四、对比介质已经使用更少的副作用
　　缺点:相比,
　　1、扫描时间通常要长得多
　　二、空间分辨率的少得多
　　三、敏感environmentals(磁场的影响)。
　　四、强磁场排除一些病人被检查与心脏起搏器,支架体:等等。
　　五、成本较高
　　六、很围、恐吓幽闭患者痛苦
　　7Not适合骨的研究
