| MiniPQ001Magnetic resonance contrast agent relaxation rate analyzerIt is a classic mini nuclear magnetic resonance device designed and developed specifically for the research and application of contrast agents. The device is equipped with a dedicated relaxation time testing software for contrast agents, which can directly test the T1 and T2 relaxation times, R1 and R2 relaxation rates, and relaxation efficiency r of contrast agent samples of different concentrations. It adopts a single board spectrometer system developed by Neway, integrating RF, temperature control, and industrial computer, compact and small; The integrated design of the coil is beneficial for faster tuning and matching. The volume and weight are greatly reduced, while the product performance is even more outstanding. Equipped with professional contrast agent testing software, the interface for bilingual selection in Chinese and English is easy to operate, learn and use. |
| Using nuclear magnetic analysis software, different concentrations of contrast agents were measured separately, and the relaxation times were obtained as shown in Table 1. Draw a correlation line between relaxation time and concentration, with the horizontal axis representing contrast agent concentration and the vertical axis representing the reciprocal of relaxation time. The results are shown in Figure 1. | Table 1 Contrast agent concentration and T2 relaxation time | | Concentration (mg/mL) | 0.04 | 0.08 | 0.1 | 0.2 | 0.4 | 0.8 | | Relaxation time (ms) | 144.640 | 74.501 | 59.749 | 30.455 | 15.340 | 7.752 | | 1000/T2 (1/s) | 6.913 | 13.423 | 16.737 | 32.835 | 65.187 | 129.007 | |
