personal or family history of multiple endocrine neoplasia type 2A (MEN 2A), multiple endocrine neoplasia type 2B (MEN 2B), neurofibromatosis, or von Hippel-Lindau disease\n* History of adrenal disease or tumor\n* Hypertension with systolic blood pressure (BP) ≥160 mm Hg or diastolic BP ≥100 despite treatment\n* Untreated or inadequately treated mental illness (indicators would include symptoms such as psychosis, hallucinations, mania, and any psychiatric hospitalization in the last year), or treatment with anti-psychotic medications that are known to affect glucose regulation.\n* Electrically powered implants (e.g. cochlear implants, neurostimulators) that might be susceptible to radio-frequency (RF) interference\n* Unable to completely avoid acetaminophen for duration of
