Brief Summary:
This is a single-center drug distribution and pharmacokinetic study of a single microdose of 18F-raltegravir given to 10 HIV-infected subjects who are either taking or not taking a raltegravir-containing ART regimen. After administration of IV 18F-raltegravir, subjects will undergo PET/MRI in order to determine the distribution of radiolabeled drug through the lymphoreticular system and other tissues throughout the entire body.

Arm Intervention/treatment
Experimental: 18F-Raltegravir Drug: 18F-Raltegravir
A single microdose of 18F-Raltegravir will be given to individuals currently being treated for HIV-1 with antiretroviral therapy.

Primary Outcome Measures :
  1. Number of patients with microdose (<2.5 millicurie; mCi) 18F-Raltegravir-related adverse events as measured by clinical observation during single intravenous dose administration and PET/MR imaging [ Time Frame: One imaging session within 1 to 6 hours following administration of 18F-Raltegravir ]
  2. Whole-body distribution (coronal through pelvis) of radiolabeled 18F-Raltegravir as determined by PET-MR scanning and quantification of radiographic regions of interest (ROI) immediately following and up to 4 hours after drug administration. [ Time Frame: One imaging session within 1 to 6 hours following administration of 18F-Raltegravir ]
