Comparison of Imaging Characteristics of uEXPLORER and Conventional PET/CT in Patients With Lung Cancer, Lymphoma, and Melanoma
To determine the minimum scan duration for fluorine-18 positron-emitting radioactive isotope-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) scans performed on a total-body PET/CT scanner that results in non-inferior image quality to 18F-FDG PET/CT scans performed on a conventional PET/CT scanner. The subject population will be patients being staged for lung cancer, lymphoma, or melanoma.

The Role of Imaging in the Diagnosis, Management and Prognosis of Possible Non-convulsive Status Epilepticus
The investigators propose a prospective study of 20 control subjects and 180 consecutive patients with possible non-convulsive status epilepticus (NCSE). The investigators will obtain three functional images of the brain: 1. Fluorodeoxyglucose positron emission tomography (FDG-PET) 2. Perfusion (and structural) magnetic resonance (MR) images 3. Computed tomography (CT) perfusion. Brain hypermetabolism/hyperperfusion is a strong argument to confirm a diagnosis of non-convulsive status epilepticus. The aim is to determine which of the three functional imaging techniques is the most sensitive and easy to obtain in the detection of hypermetabolism/hyperperfusion. The investigators will determine which EEG patterns are associated with hypermetabolism/perfusion. The investigators will further study and describe the management with antiseizure medication and outcome of the group with possible non-convulsive status epilepticus WITH hypermetabolism/hyperperfusion versus the group with possible non-convulsive status epilpticus WITHOUT hypermetabolism/hyperperfusion. The investigators will make recommendations for an imaging protocol in possible NCSE for widespread use. The aim is to offer guidelines to incorporate imaging in the diagnosis, management and prognosis of NCSE in patients with the ictal-interictal continuum.
