Become big, and the T1 values of liver cancer are bigger, make t1 weighted image, can distinguish liver's benign tumour and malignant tumour；By adjusting magnetic field
Can section needed for unrestricted choice.Other imaging techniques, which can be obtained, can not approach or be difficult to the image close to position.For intervertebral
Disk and spinal cord, sagittal plane, coronal-plane, axial imaging can be made, it can be seen that nerve root, spinal cord and neuromere etc..Unlike CT only
The cross section vertical with people's long axis of body can be obtained；There is no ionization radiation injury to human body.
But caused various noises in running are equally existed, it may make what the hearing of some patients sustained damage
Shortcoming.
