Table 1:

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, %
Sequence	Pre-Enhanced	Post enhanced	Degree of Contrast Enhancement, Mean ± SD	CER, Mean ± SD, %
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).
