CR of metastases detected with T1SE and T1IR

Sequence	CR, Mean±SD
	Tumor to WM		Tumor to GM		Tumor to CSF
	Pre-Enhanced	Postenhanced	Pre-Enhanced	Postenhanced	Pre-Enhanced	Postenhanced
T1SE	0.2 ± 0.1^*	0.6 ± 0.4^†	0.1 ± 0.1^*	0.9 ± 0.5^†	0.9 ± 0.3^*	2.8 ± 1.1^*
T1IR	0.3 ± 0.1^*	0.3 ± 0.2^†	0.2 ± 0.1^*	0.7 ± 0.3^†	2.3 ± 0.8^*	4.9 ± 1.4^*

Note:—T1SE indicates T1-weighted spin-echo; T1IR, T1-weighted inversion recovery; CR, contrast ratio; WM, white matter; GM, gray matter.
* T1IR is more sensitive (P < .05).
† T1SE is more sensitive (P < .05).
