Methods: 58 patients with diabetes in our hospital were selected as the observation group (from March 2019 to March 2021), and 58 patients with physical examination in the same period were selected as the control group. All of them were examined by color Doppler ultrasound, and the results were observed. Results: compared with the control group, the observation group had smaller inner diameter of lower limb blood vessels, slower blood flow, larger media thickness, higher incidence of lower limb vascular diseases and higher incidence of various types of lower limb vascular diseases (P < 0.05). Conclusion: in the diagnosis of diabetic lower extremity vascular diseases, color Doppler ultrasound has high accuracy, which can provide basis for early diagnosis and treatment of diseases, and is worth learning from.展开更多

Methods: from April 2020 to December 2021, 62 patients with polypoid lesions of gallbladder in our hospital were selected for clinical diagnosis, all of whom were confirmed after pathological diagnosis. The patients were diagnosed by transabdominal color Doppler ultrasound before pathological diagnosis. To analyze the similarities and differences of different types of benign gallbladder polypoid lesions by abdominal color Doppler ultrasound, the differences of blood flow signal, arterial maximum blood flow velocity and resistance index between benign and malignant gallbladder polypoid lesions by color Doppler ultrasound, the detection rate of benign gallbladder polypoid lesions by ultrasound, and the diagnostic efficiency of abdominal color Doppler ultrasound for benign gallbladder polypoid lesions. Results: (1) There was no significant difference in the base width, echo signal distribution, number and shape distribution of inflammatory polyps, cholesterol polyps and gallbladder adenoma polyps between groups (P > 0.05);The thickness of gallbladder wall in patients with cholesterol polyps is lower than that in patients with inflammatory polyps and gallbladder adenomas, and the difference is statistically significant (P < 0.05). (2) The proportion of blood flow signals of benign gallbladder polyps in grade 0 (50.98%) and grade 1 (37.25%) is higher than that of malignant gallbladder polyps, and the VMAX (15.32±1.85) cm/s and RI(0.58±0.05) of benign gallbladder polyps are lower than that of malignant gallbladder polyps, and the difference is statistically significant (P < 0.05) (3) The detection rate of inflammatory polyps, cholesterol polyps and gallbladder adenomas diagnosed by abdominal color Doppler ultrasound has no significant difference compared with pathological diagnosis, P > 0.05. (4) The sensitivity, specificity and diagnostic coincidence rate of transabdominal color Doppler ultrasound for benign polypoid lesions of gallbladder were 92.16%, 81.82% and 90.32% respectively. Conclusion: the implementation of abdominal color Doppler ultrasound can realize the differential diagnosis of polypoid lesions after evaluating the morphological characteristics of polypoid lesions of gallbladder and imaging indications such as blood flow signal, blood flow velocity and blood flow resistance of lesions in color Doppler ultrasound mode, and it is of classified diagnostic value.展开更多

Methods: from January 2020 to January 2022, 76 patients (observation group) who underwent cervical vascular examination in our hospital and 76 healthy persons (control group) who underwent physical examination in our hospital were selected as the research nodes, and the relevant data were analyzed. Color Doppler ultrasound examination was performed in both groups, and the examination results were compared. Results: 76 patients in the observation group were found to have carotid atherosclerotic plaques in 61 patients after color Doppler ultrasound examination, accounting for 80.26%. In addition, 68 patients (89.47%) with common carotid bifurcation in the neck were detected, among which 3 patients were internal carotid artery and 2 patients were vertebral artery. In the control group, 76 patients were examined, and 8 patients were found to have plaques, accounting for 10.53%, 6 patients were common carotid artery, and 1 patient was internal carotid artery. The incidence of carotid atherosclerosis plaque in the observation group was higher than that in the control group (p < 0.05). The internal diameter of left vertebral artery (3.42±0.54)mm and the internal diameter of right vertebral artery (3.05±0.85)mm in the observation group were all lower than the internal diameter of left vertebral artery (4.28±0.33)mm and the internal diameter of right vertebral artery (3.99±0.86)mm in the control group (p < 0.05). The left vertebral artery blood flow (137.85±42.55)ml/min, right vertebral artery blood flow (128.34±41.55)ml/min, total vertebral artery blood flow (224.36±51.55)ml/min in the observation group were all lower than those in the control group (188.15±42.61)ml/min, right vertebral artery blood flow (172.02±41.66)ml/min, total vertebral artery blood flow (396.25±58.35)ml/min, with statistical significance (p < 0.05). By analyzing the actual situation of 76 patients in the observation group, it was found that there was significant difference in carotid artery pulsatility and resistance index between patients over 40 years old and patients under 40 years old, i.e. there was no difference in pulsatility and resistance index of common carotid artery, internal carotid artery and external carotid artery, P>0.05. Conclusion: in the cervical vascular examination, through the color Doppler ultrasound examination, we can understand the actual situation of patients' internal carotid artery, vertebral artery and other related artery blood flow, and provide an effective reference for clinical diagnosis and treatment. Therefore, it is worthy of clinical application of this model.展开更多
