Peripheral pulmonary nodules: Relationship between multi-slice spiral CT perfusion imaging and tumor angiogenesis and VEGF expression

Table 7 Relationships between adenocarcinoma differentiations and parameters

Parameter	BV (p)	BF (p)	MTT (p)	PS (p)	PH (p)	PHpm/PHa (p)	MVD (p)
Well (n = 9) and moderately (n = 10)	0.679	1.000	0.198	0.999	0.738	0.615	0.945
Well (n = 9) and poorly (n = 5)	0.001	0.018	0.897	0.011	0.066	0.038	0.002
Poorly (n = 5) and moderately (n = 10)	0.003	0.025	0.130	0.038	0.035	0.014	0.002

*Because there are fewer cases of squamous cell carcinoma, large and small cell carcinoma, relationships between their differentiations and parameters were not compared. In the case of adenocarcinoma, BV, BF, PS, PHpm/PHa, and MVD between poorly and well differentiation and between poorly and moderately differentiation were statistically significant (all P < 0.05).
