ABSTRACT
Objective:To investigate the image quality of digital radiography (DR) versus neoimaging (NE) technique in imaging of the spine and lower extremities in a standing position. Methods:The clinical data of 163 patients who underwent DR of the thoracolumbar spine and full-length lower extremities in a staining position in June to December 2019 in Taizhou Hospital of Zhejiang Province were retrospectively analyzed. Conventional DR images were designated as pre-processing images. NE software technique-processed images were designated as post-processing images. The image quality between the two techniques were compared.Results:Grade I image quality was observed in 91.41% (149/163) of DR images, and grade II image quality in 8.59% (14/163) of DR images. Grade I image quality was found in 93.87% (153/163) of NE software-treated images, and grade II image quality in 6.14% (10/163) NE software-treated images. There was significant difference in image quality between before and after NE software processing ( χ2 = 10.220, P = 0.001). Conclusion:NE software technique can seamlessly splice conventional DR images of the spine and low extremities in a standing position without being limited by equipment. Thus, high-quality images can be obtained to meet the requirement of clinical diagnosis. This study is innovative.
ABSTRACT
Small(≤2 cm)pancreatic neuroendocrine neoplasm(pNEN) is a very special subgroup of pNEN featuring a small size, concealed pathogenesis, indolent course and remarkable heterogeneity.Differences in its diagnosis and interventional criteria have evolved from routine pNEN.During recent years, the incidence of small pNEN has increased sharply, while optimal management strategy of this subgroup still remains controversial.In this paper, the biological characteristics, pathological classification, diagnosis, intervention indication and therapeutic principles of small pNEN are reviewed based on recent researches, and current situations of diagnosis and treatment of small pNEN are summarized.
ABSTRACT
Objective To seek a rational method of estimating the demands for medical services so as to work out regional health planning in a scientific way. Methods A metropolis including 19 counties and districts was selected as a region and demands for medical services were forecasted via retrospective analysis and the econometric model. Results A model of the demands for outpatient and inpatient services was obtained based on the impact of many social and economic factors on medical health services, and illustrations were given to indicate the demands for medical health services in the 19 counties and districts in future when prices should rise by 15% and 20%. Conclusion The econometric model can be used as a tool for estimating the demands for medical health services, and yet improvements need to be made.
