Objective To explore the change characteristics of early renal blood infusion in patients with diabetes and its relation-ship with fasting blood sugar by using multi-slice spiral CT (MSCT)perfusion scan.Methods Thirty cases of T2DM patients within five years of disease course that meet clinical diagnostic criteria (poor DN glycemic control group and good DN glycemic control group with 1 5 cases in each group)and 1 5 cases in the control group underwent bilateral renal perfusion scan using 64-detector spiral CT,thus obtaning their cortical perfusion parameters of bilateral kidneys,including blood flow (BF),blood volume (BV),mean transit time (MTT)and capillary permeability surface (PS).At the same time,for each case,fasting glucose,blood urea nitrogen, serum creatinine and blood uric acid value on the third days after and before perfusion were also measured;the glomemlar filtration rate (C-GFR)was estimated.Statistical analysis was performed on all of these obtained values.Results (1).For the poor DN gly-cemic control group,the average BF value,average BV value and average PS value were reduced,average MTT was prolonged sig-nificantly,and compared with normal group,average BF value and average MTT were statistically significant (P 0.05)for both normal control group and DN groups in the third day before and after renal CT perfusion imaging examination.Conclusion BF,BV and MTT of MSCT perfusion scan can reflect the characteris-ticsof early renal blood infusion in patients with diabetes.And changes of fasting blood sugar in patients with diabetes may influence mean BF and mean MTT of kidney.
