Contrast agents analyzer

TD - NMR imaging analysis

Minispec contrast analyzer is used to research is called "the MRI contrast agent" for the effect of proton NMR relaxation in the water or fat.Contrast agents for enhanced magnetic resonance image of each organization, the contrast between the otherwise it will be hard to distinguish.Especially in the central nervous system, digestive system, lymphatic system and cardiovascular system, liver, breast and lung tissue.

To design a successful contrast agents need to meet each other at the same time conflict of drug and magnetic resonance imaging (mri) features: although Mn2 + and Gd3 + metal ions could lead to a very good contrast enhancement, but they need to be chelate, because application concentration of "naked ion" are poisonous.

Minispec mq - series desktop nuclear magnetic resonance instrument in characterization and validation features of contrast agents has played a key role.Its task is to check the accumulation of fat and water quality of T1 and T2 relaxation time shorten.Fat and water quality is mainly responsible for MR image.

Contrast agents analyzer:

• Mq60: for about 1.5 T relaxation time analysis of clinical magnetic resonance imaging system
• Mq40: for about 1.0 T relaxation time analysis of clinical magnetic resonance imaging system
• Mq20: for about 0.5 T relaxation time analysis of clinical magnetic resonance imaging system
• Mq10: used for measuring the relaxation time parameters of 0.23 T
• Mq7.5: used for measuring the relaxation time parameters of 0.17 T

• Longer time to MRI
• Just press the button, can operate all of the usual pulse sequence T1, T2 relaxation time analysis
• Easy to install, table size, no need for high frequency and rf shielding
• No refrigerant permanent magnets
• Simplicity of sample processing and measurement
• Compared with MRI system, the price is very favourable
• Only need a small amount of expensive contrast agent
