Table 2.
Comparison of SNR from the normal brain for SE, GE and GEFC pulse sequences pre, and at the respective time points: 20, 120 min and 24 hrs for SE; 30, 130 min and 24 hrs for GE; 31, 131 min and 24 hrs for GEFC post iv tail injection of the targeted contrast agent
| Pre | 20/30/31 min | 120/130/131 min | 24 hrs | |
|---|---|---|---|---|
| SE |
25.3 |
19.7 |
25.9 |
26.2 |
| GE |
29.0 |
18.7 |
24.5 |
25.4 |
| GEFC | 31.2 | 21.1 | 25.9 | 29.8 |
The standard deviation was smaller than ±1.3 for each measurement. The SNR for GE is corrected for the bandwidth difference (0.8).
