Comparison of electromagnetic navigation bronchoscopy localization and CT-guided percutaneous localization in resection of lung nodules: A protocol for systematic review and meta-analysis.

Background: This study aimed to evaluate the efficacy and safety between electromagnetic navigational bronchoscopy (ENB) and computed tomography (CT)-guided percutaneous localization before resection of pulmonary nodules.

Methods: Pubmed, Embase, Web of Science, and the Cochrane Library databases were searched from January 1, 2000 to April 30, 2022, for relevant studies. Two reviewers conducted the search, selection, and extraction of data from eligible studies.

[Correlation analysis between degenerative spondylolisthesis and T2WI hyperintensity on MRI of interspinous ligament].

Objective: To explore the relationship between lumbar degenerative spondylolisthesis and T2WI high signal in the interspinous ligament in MRI in order to improve the understanding of the signal changes of the interspinous ligament.

Methods: The clinical data of 43 patients with clinically diagnosed lumbar degenerative spondylolisthesis were collected from March 2018 to March 2020, there were 19 males and 24 females, aged 50 to 92 years with an average of 69 years old. Using picture archiving and communication systems (PACS) to access images and record the distribution and incidence of T2WI high signal in the interspinous ligament between the slipped and non-slipped segments.
