Value of Magnetic Resonance Images and Magnetic Resonance Spectroscopy in Diagnosis of Brain Tumors under Fuzzy C-Means Algorithm

Table 1

Imaging parameters of MRI.

Items	Parameters	Functions
Time of repetition (θa)	1980 ms	It determined the value of θ1.
Delay time of echo (θb)	2.28 ms	The contrast of θ2 would be affected.
Frequency encoding direction	245 mm245 mm165 mm	The smaller the value, the higher the resolution.
Flip angle	8°	It defined echo pulse sequence.
Volume of a unit voxel in a brain image	1 mm³
