Tumor signal intensity, degree of contrast enhancement, and CER detected with T1SE and T1IR
| Sequence | Signal Intensity, Mean ± SD | Degree of Contrast Enhancement, Mean ± SD | CER, Mean ± SD, % | |
|---|---|---|---|---|
| Pre-Enhanced | Post enhanced | |||
| T1SE | 174.2 ± 17.0 | 346.9 ± 88.8 | 172.8 ± 93.4* | 101.7 ±5 9.4† |
| T1IR | 270.7 ± 47.6 | 492.9 ± 94.1 | 222.2 ± 108.4* | 90.0 ± 60.7† |
Note:—T1SE indicates T1-weighted spin-echo; T1IR, T1-weighted inversion recovery; CER, contrast-to-enhancement ratio.
* T1IR is higher (P < .001).
† There is no difference between the 2 sequences (P > .05).
