Patient Care

The Division of Nuclear Medicine provides the highest quality patient care at various sites in Colorado.  Our state of the art equipment and drive for excellence allows us to provide the most advanced technologies for patient care.  The Division consists of five faculty members.  Dr. Bagrosky is board certified in Diagnostic Radiology and has additional fellowship training in Nuclear Radiology and Pediatric Radiology.  His practice is shared between the University of Colorado Hospital and Children’s Hospital of Colorado.  Drs. Koo, and Kwak are dual board certified in Diagnostic Radiology and Nuclear Medicine.  They practice primarily at the University of Colorado Hospital.  Dr. Robert Quaife is board certified in Nuclear Medicine, Internal Medicine, and Cardiology, while Dr. Moloo is board certified in Internal Medicine with additional fellowship training in cardiac CT and nuclear cardiology.  Both specialize in cardiac imaging at the University of Colorado Hospital.


The Division of Nuclear Medicine participates in the full range of educational activities for fellows, residents, medical students, and other members of the medical community.  The division sponsors a fellow in nuclear radiology through our ACGME accredited fellowship program.


Faculty members in the Division of Nuclear Medicine conduct research in a wide range of areas.  Many projects involve the radiopharmacy program, under the direction of Dr. Peter Smith-Jones, and the faculty work closely with Dr. Smith-Jones to utilize and develop novel radiopharmaceuticals. Faculty members are also actively involved with the Colorado Translational Research Imaging Center (CTRIC) and work collaboratively with researchers on campus and throughout the state.
