The objective of this study is to examine critical aspects of radiation exposure, dose delivery, and systemic yttrium-90 (Y90) exposure related to the infusion of Y90 microspheres for treatment of hepatocellular carcinoma (HCC) and other metastatic liver disease.
Purpose: To compare the radiation exposure in patients during Endoscopic retrograde cholangiopancreatography (ERCP) done by Endoscopists formally trained in judicious use of fluoroscopy versus ERCPs done by Endoscopists without such formal training. Research design: This is an observational study to compare radiation exposure in patients during ERCPs based on formal training. Procedures to be used: None Risks and potential benefits There are no risks associated with this study as it is a retrospective chart review. Potential benefits include the knowledge gained from this study which may be of help to patients in the future. Importance of knowledge that may reasonably be expected to result The knowledge gained from this study may be of help to provide new insights and develop newer guidelines for radiation use in the future.
Fluoroscopy is performed when placing a lead during a sacral neuromodulation procedure. During lead placement, subjects will receive either conventional or experimental fluoroscopic settings. The radiation exposure will be compared between the two groups.
Brain metastases are a source of much morbidity and mortality in adults with primary solid malignant tumors. With improvements in systemic therapy that prolong survival but have limited central nervous system penetration, patients with brain metastases are at increasing risk of developing and experiencing long-term side effects from treatment of brain metastases. The overarching goal of this study is to better understand the determinants of RT-associated changes in white and gray matter function and associated neurocognitive decline.
