Defining Response Criteria for PET Scans for People With Neuroendocrine Tumors
People with neuroendocrine cancer typically have imaging scans before and after treatment, including positron emission tomography (PET) scans. The scans are analyzed using a set of criteria that describes how the disease has responded to treatment. The purpose of this study is to establish new criteria for doctors to use …
Role of Diffusion Tensor-magnetic Resonance Imaging in Investigating Sensorineural Hearing Loss
DTI and auditory tractography can be incorporated into the diagnostic toolkit for patients who are scheduled to undergo cochlear implantation and whose standard assessments have been unable to determine the functional integrity of the auditory pathway. These techniques aid in decision-making processes regarding potential outcomes, determining the optimal side for …
Research on the Mechanisms of Treatment Non-response in Inflammatory Bowel Disease Based on Multi-omics Technology
In recent years, biologic agents such as infliximab, vedolizumab, and ustekinumab have demonstrated tremendous potential in the treatment of inflammatory bowel disease (IBD), altering the traditional treatment paradigm for IBD. Despite their significant efficacy, there remains a subset of patients who do not respond to biologic agents, necessitating research into …
