With the economic and science technology development, the advanced medical devices have developed gradually, among of them, as we know, B ultrasound, MRI and Computed Tomography are applied widely in hospital. But most of people think that price is more expensive and the examination effects are better. In fact, it is a misunderstanding. They have their advantages.

Tumor resolution of Computed Tomography is higher than B ultrasound; If it is a small bump of 1 ~ 2 cm, CT show rate is 88%, but B ultrasound is only 48%, especially Cerebral hemorrhage, hydrocephalus, brain artery malformation and brain tumors; CT is good at that.

On gallbladder disease diagnosis, B ultrasound accuracy is 95% and is more than CT; Liver cirrhosis, fatty liver, splenomegaly and bowel lesions are easy to be diagnosticed by it.

 MRI can not only avoid the CT effect for people, but also it can display lesions tissue. At present, it is easy to diagnostic bone, joint, spinal cord, pelvic viscera, uterus, mediastinal disease and heart vascular lesions and identify myocardial infarction, but its cost are expensive.

Therefore, CT, B ultrasound and MRI have their characteristics and doctors should choose appropriate machine in accordance with patient’s condition.
