Value of ultrasound micro-flow imaging combined with serum inflammatory factors in the diagnosis of diabetic kidney disease

Objective To investigate the value of ultrasound micro-flow imaging (MFI) combined with serum inflammatory factors in the early diagnosis of diabetic kidney disease (DKD). Methods A total of 92 patients with DKD who were admitted to The Affiliated Hospital of Qingdao University from June 1, 2022 to June 30, 2023 were enrolled as DKD group, and 64 patients with type 2 diabetes mellitus (T2DM) who were admitted to our hospital during the same period of time were enrolled as T2DM group. Related data were collected for the two groups, including clinical indicators, ultrasound blood flow parameters, and serum inflammatory factors. Ultrasound blood flow parameters included MFI-value, left renal interlobar artery resistance index (RI1), right renal interlobar artery resistance index (RI2), left renal interlobar arterial peak velocity (PSV1), and right renal interlobar arterial peak velocity (PSV2). The Spearman method was used to investigate the correlation of MFI-value with clinical indicators and serum inflammator
