13 tumors with negative SSTR2 and 52 tumors with positive SSTR2 were evaluated.
The positive SSTR2 group showed male(48.1% vs 84.6%，P < 0.05 ),
hypointense signal on arterial phase (23.1% vs 76.9%,
P < 0.05),
portal venous phase (13.5% vs 61.5%,
P < 0.05),
and delayed phase (9.6% vs46.2%,
P < 0.05) less frequently than the negative SSTR2 group,
as opposed to the G1(34.6 % vs 7.7%，P < 0.05 ).
The CNRs of arterial phase of the positive SSTR2 group were larger than the negative SSTR2 group (-0.0097 vs -0.7953,
Using binary logistic regression analysis,
the contrast enhancement on arterial phase was an independent significant differentiator of the positive SSTR2 group from the negative SSTR2 group.
The optimal cut-off value for the identification of the positive SSTR2 group was hyper/isointense signal on arterial phase (sensitivity 75.47%,
