Comparison of cerebral blood flow in oral somatic delusion in patients with and without a history of depression: a comparative case series

Table 4 Mean cerebral blood flow (mCBF) values and mean imipramine equivalent doses

		Mean of imipramine equivalent dose	mCBF values
		Mean of imipramine equivalent dose	Whole brain	Left hemisphere	Right hemisphere
non-depression group	total (n = 17)	38.53 ± 65.57	43.15 ± 2.85	43.31 ± 2.78	43.45 ± 2.46
	taken antidepressants (n = 8)	81.88 ± 75.97	42.43 ± 3.59	42.60 ± 3.51	42.91 ± 3.19
	no antidepressants (n = 9)	0	43.79 ± 2.00	43.93 ± 1.93	43.93 ± 1.64
depression group	total (n = 10)	58.50 ± 51.91	39.10 ± 2.89	39.03 ± 2.82	39.02 ± 3.10
	taken antidepressants (n = 8)	73.13 ± 47.35	38.71 ± 3.03	38.70 ± 2.91	38.44 ± 3.21
	no antidepressants (n = 2)	0	40.65 ± 2.19	40.35 ± 2.76	41.35 ± 0.78

No difference in the imipramine equivalent doses was observed between the non-depression and depression groups. No difference in the mCBF values was observed between subjects taking and not taking antidepressants. However, focusing on only the patients who took antidepressants, the mCBF value in the depression group was significantly lower than that in the non-depression group.
