Radiopharmaceutical therapy for leptomeningeal metastatic disease

This research will study brain and cardiovascular health in transgender adult patients receiving gender-affirming hormone therapy at two timepoints: before hormone therapy begins, and after four to six months of therapy. The goal of the study is to assess links between gender affirming hormone therapy, cardiovascular health and brain structure and function. MRI will be used to analyze brain structure and brain blood flow. Body fat will be assessed by Dual X-ray Absorptiometry and aerobic fitness will be assessed using a treadmill test. This analysis is also relevant to other conditions involving hormone disruptions such as puberty, menopause, pregnancy, aging, postpartum, diabetes and obesity.
