Methods: 68 children were examined for major soft trauma, and all children were scanned with CT. To observe the CT positive status of children's head and the operation of Neurosurgery (NSP), record the treatment intervention, diagnostic intervention and death of CT positive children, and analyze the relationship between CT positive and NSP. The CT results of 68 children were 26 cases, accounting for 30.24%. In addition, ns10 was completed in 10 cases, accounting for 14.71%.22 cases (32.35%) used treatment intervention, 46 cases (67.65%) used diagnostic intervention. Two children died of CT positive, accounting for 7.69%.There was significant difference between positive TCC and DSN in children with different gender, age and injury cause (P < 0.05).Male, age ≥ 6 years old, fall injury is closely related to TNT positive and PSN. Conclusion: CT head scan has certain guiding significance for the operation of children with minor head injury. Male, age ≥ 6 years old and autumn injury may be important predictors of NSP treatment in children with mild head injury. Based on the above characteristics, we can determine which groups of children with minor head injuries can benefit from intake and NSP treatment, which can provide a basis for clinical diagnosis and treatment.展开更多

Among 16 patients with normal head CT,6 were cured,8 were improved,and effective rate was 87.5%. Among 34 infants with high rhythm disorder,8 were cured,21 were improved,effective rate was 85.29%. For 13 infants with abnormal EEG of other types,no infants were cured,4 were improved,and effective rate was 30.8%.Conclusion Changed head CT not various EEG has no significant effect on prognosis of infant spasm(P >0.05).Prognosis is favorable in infants with high rhythm disorder(P<0.01).展开更多

PET/CT has been used for radiotherapy planning, providing useful information to the Radio-oncologist about the localization, size and metabolic activity of tumor lesions. In this paper, we show advantages of the 18F-FDG PET/CT respect to simple CT imaging for target volume delineation in patients with diagnosis of Squamous Head and Neck Carcinoma that has been scheduled to undergo a hypofractionated radiotherapy treatment. On ten studied patients, the target volume defined from PET/CT images was less extensive than those defined from simple CT images. In six patients the target volume was significantly less extensive and in two of them a new lymph node disease was reported, re-staging and corresponding target volume was also delineated with less extensive margins from PET/CT images. A greater accuracy in delineating the volumes and improving the distribution of doses in the planning of the radiant treatment in these patients was possible, allowing a high precision in the delivery of the prescribed dose to the target volume diminishing the maximum dose to the adjacent healthy tissues. In conclusion we show that the use of 18F-FDG PET/CT was superior than the simple CT as the primary modality of imaging for hypofractioned radiotherapy treatment planning in patients with Squamous Head and Neck Carcinoma.展开更多

Methods: 150 patients with cerebral artery stenosis and acute stroke treated in our hospital from January 2018 to June 2021 were selected. They were randomly divided into two groups with 75 cases in each group. Among them, the patients in the control group mainly underwent cerebrovascular stenting with the assistance of fluoroscopy machine, while the patients in the study group intervened in head and neck CT on this basis, analyzed the clinical data of the patients, compared the incidence of adverse conditions and postoperative recurrence of the two groups, and studied the specific contents. Results: the effect of CT nerve intervention was very obvious. Compared with the traditional fluoroscopy machine, the incidence of adverse reactions in the study group was significantly lower. At the same time, in terms of postoperative recovery, the recovery effect was better, and there were no more language dysfunction and hemiplegia. The results were statistically significant. Conclusion: head and neck CT has good clinical value in nerve intervention. In the clinical aspect, its popularization and use can effectively diagnose the patient's condition and provide a certain reference value for improving the patient's health.展开更多
