NCT02591654
The purpose of this study is to test two imaging techniques, one called whole body (WB) diffusion weighted (DWI) magnetic resonance imaging (MRI) (WB-DWI MRI), and another called Fluorine-18 3'-deoxy-3'-fluorothymidine positron emission tomography (PET) (F-18-FLT PET). The goal is to see whether these imaging techniques would allow the study doctors to see changes in the size of a tumor earlier for patients with metastatic melanoma receiving Pembrolizumab (MK-3475).
NCT00537134
The management of patients with unruptured aneurysms is controversial. Patients with unruptured aneurysms may suffer intracranial hemorrhage, but the incidence of this event is still debated. Endovascular treatment can prevent rupture, but involves immediate risks; furthermore, successful treatment does not eliminate all risks. A randomized trial may be the best way to demonstrate the potential benefits of endovascular over conservative management of unruptured aneurysms.
