fMRI Study of Early Brain Injury in Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease involving multiple organs and systems. The central nervous system is one of the most commonly involved parts, and the involvement of the nervous system is called neuropsychiatric lupus, which is one of the most common complications of SLE and the main …
Validation of Rapid On-site Diagnostics in Early Stage Lung Cancer Sampling With a Higher Harmonic Generation Microscope
The aim of this study is to verify a new microscopic technique in diagnosing patients suspected of lung cancer. Patients will undergo navigational bronchoscopy or surgical resection as a part of standard of care. Biopsies taken during this procedure will be imaged for a few minutes with a higher harmonic …
Prostate Assessment With Restriction Spectrum Imaging (RSI) MRI
This single-center study will enroll 40 male participants to complete 2 diffusion magnetic resonance images within 30 days of each other.
Clinical Analysis of Early Hormones Between Patients With Traumatic Brain Injury and Cerebral Hemorrhage
Our understanding of neurosecretory dysfunction after TBI is still insufficient, and the number of patients with neuroendocrine dysfunction caused by craniocerebral trauma may be underestimated, especially the neuroendocrine changes related to HPA axis in the early stage after craniocerebral trauma. Moreover, there are few and fragmentary literature data on the …
Magnetic Resonance Imaging and Ultrasound Comparison With Load Evaluation
Facioscapulohumeral dystrophy (FSHD) is one of the most common hereditary neuromuscular disorders (NMD), with an estimated prevalence of 2000 patients in the Netherlands. Magnetic resonance imaging (MRI) and muscle ultrasound have contributed to an enhanced understanding of the pathophysiology of Facioscapulohumeral Muscular Dystrophy (FSHD). Previously, our group demonstrated the potential …
DNA Methylation Combined With Artificial Intelligence Imaging to Identify Lung Nodules
Lung cancer is the leading cause of cancer deaths,and the key to reducing mortality in lung cancer patients is early diagnosis and treatment.Currently,peripheral blood DNA methylation is a novel in vitro molecular marker for tumors.Meanwhile artificial intelligence diagnostic system can further improve the diagnostic ability.The purpose of this study is …
