RESUMEN
@#The increasing number of pulmonary nodules being detected by computed tomography scans significantly increase the workload of the radiologists for scan interpretation. Limitations of traditional methods for differential diagnosis of pulmonary nodules have been increasingly prominent. Artificial intelligence (AI) has the potential to increase the efficiency of discrimination and invasiveness classification for pulmonary nodules and lead to effective nodule management. Chinese Experts Consensus on Artificial Intelligence Assisted Management for Pulmonary Nodule (2022 Version) has been officially released recently. This article closely follows the context, significance, core implications, and the impact of future AI-assisted management on the diagnosis and treatment of pulmonary nodules. It is hoped that through our joint efforts, we can promote the standardization of management for pulmonary nodules and strive to improve the long-term survival and postoperative life quality of patients with lung cancer.
RESUMEN
Objective: To determine whether the effectiveness of core stability exercises correlates with the severity of spinal stenosis in patients with degenerative lumbar spinal stenosis
Methods: Forty-two patients with degenerative lumbar spinal stenosis treated in the department of orthopedics of our hospital between May 2013 and January 2016 were included in the study. All the patients performed core stability exercises once daily for six weeks, and the clinical outcomes were evaluated using Japanese Orthopaedic Association [JOA] score and self-reported walking capacity. The anteroposterior osseous spinal canal diameter was measured to evaluate the severity of spinal stenosis. The correlation between the stenosis degree and the differences of Japanese Orthopaedic Association score or self-reported walking capacity at baseline and after treatment were analyzed
Results: The patients were divided into three groups according to the spinal stenosis degree. In the three groups, there was no significant difference in JOA or self-reported walking distance at baseline [p>0.05] and after treatment [p>0.05]. The JOA scores and self-reported walking distance were significantly increased after treatment [p<0.05] in any of the three groups when compared to the baseline. Also, there was no significant correlation between the stenosis degree and the difference of JOA [p>0.05] or self-reported walking distance [p>0.05]
Conclusion: There was no significant correlation between the effectiveness of core stability exercises and the severity of spinal stenosis in patients with degenerative lumbar spinal stenosis
RESUMEN
Objective To recognize CT signs of parapharyngeal space (PPS) changing in nasopharyngeal carcinoma (NPC) further.Methods 30 patients with proven NPC by biopsy were performed CT and MR scanning before radiotherapy. Results According to CT findings,four types of PPS display in 30 cases were found,each of which was observed and compared with MR findings and were as follows: (1)PPS ,which had no changing on CT, showed fat-filled triangular space continuously on MRI. (2) PPS, which became narrow and linear hypodense on CT,showed that fat intensity was pressed, but continuously on MRI; (3) PPS, which became narrow and linear hyperdense on CT,showed fat intensity,was pressed exceedingly but continuously either on MRI. (4)PPS,which was diminished on CT, showed the mass occupied PPS and lateral pterygoid muscles was pushed, medial fatty space of which was diminished, but intensity of medial or lateral pterygoid muscles was normal or abnormal on MRI. Conclusion (1)When PPS becomes narrow on CT,whether PPS shows hyperdense or hypodense,the mass makes a breakthrough PPS. (2) When PPS is diminished completely on CT,the mass steps PPS to the infratemporal fossa.
