Table 1.
Relaxation times of iodinated contrast material, blood and physiologic saline at 1.5T1
| T1 relaxation time (ms) | T2 relaxation time (ms) | |
| Iodinated contrast (Iopamidol 300 mg/L)2 | Approximately 1100 | Approximately 80-100 |
| Blood3 | 1200-1400 | 290-320 |
| Physiologic saline4 | Approximately 3000 | Approximately 1800 |
1
There is notable difference between the relaxation times (RT) for physiologic saline and iodinated contrast (ICM) or blood. While ICM and blood have closer and similar RT;

Modified from Hergan et al[2], T1 values represent time after correction for known 25%-40% increase with every doubling of the magnetic field strength;
