ON THE COVER

Integration of a whole-body PET system with MRI would make possible whole-body kinetic studies showing the underlying anatomy, with applications in areas such as pharmacokinetics, dosimetry, and cell- trafficking studies. The obvious objection to such a system is its likely expense. To realize such a system in anything other than an elite medical research environment would require significant reductions in cost. But putting cost aside, it is likely that the PET component of such a system could be built even with current technology, and with recent developments the combination of PET and MRI is looking increasingly feasible.
