Table 2. The association between FP-CIT SPECT imaging and the multivariate SCA approach in classifying AD and DLB in accordance with clinical diagnosis.

	AD (n=31)		DLB (n=27)
	FP-CIT positive	FP-CIT negative	FP-CIT positive	FP-CIT negative
Multivariate DLB	1	2	17	2
Multivariate AD	4	24	5	3

AD, Alzheimer's disease; DLB, dementia with Lewy bodies; MMSE, mini-mental state examination; SCA, spatial covariance analysis; SPECT, single-photon emission computed tomography.
