Nuclear Medicine and Molecular Imaging Division


Nuclear medicine is a specialized service division within the Russell H. Morgan Department of Radiology and Radiological Science that utilizes radioactive material to assess the function of organs or systems within the body. The mission of the Division of Nuclear Medicine and Molecular Imaging (DNMMI) is to lead in discovery, teaching and application of methods in precision health for justly distributed and improved patient-centric care.

Nuclear medicine helps diagnose and treat many diseases, such as cancer, heart disease and infection by looking at organ function to get deeper molecular signatures in health and in disease. Techniques or modalities such as Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT) administer small amounts of radioactive substances to the patient that serve as radiotracers.

These radiotracers map out organ function that can be fashioned into functional or molecular images. That creates more than just a picture of the organ, but an image that contains data that can be analyzed and presented. It is a quantitative (measurable) image. These unique images provide information that often cannot be obtained using other imaging procedures, such as CT or MRI, and offers the ability to identify disease in early stages.

Meet Our Experts

The DNMMI consists of full-time clinical faculty, many certified in both nuclear medicine and radiology, and research faculty that also work to fulfill the academic mission of Johns Hopkins Medicine. Meet our clinical and research faculty.


Aligning with the mission of Johns Hopkins Medicine to improve the health of the community and the world by setting standards of excellence in clinical care, research and education, the DNMMI conducts research and develops educational programs and procedures to supply patients with the best and most innovative care.

The DNMMI research labs, including The Center for Translational Molecular Imaging, advances nuclear medicine and molecular imaging through pioneering discoveries and translational research performed by our research faculty and physician-scientists. Our experts continually discover new imaging agents as well as repurpose existing agents in novel and exciting ways. For example, the DNMMI is working closely with the Departments of Urology, Genitourinary Oncology, and Radiation Oncology to discover therapeutic agents for prostate cancer, with DNMMI agents already being issued worldwide to help patients manage this disease.

DNMMI currently works with partners such as the National Institutes of Health, key industrial partners, and academic collaborators worldwide to create programs to develop agents beyond the standard agents for PET and SPECT. Those collaborations assist in fostering the development of new medical imaging techniques, disease treatments and interventional procedures from basic discovery to clinical trials – including therapeutic trials. The division produces hundreds of publications yearly and garners millions in research funding as well as strong commercial ties and an extensive patent portfolio.


Our nuclear medicine residency program has been ranked No. 1 in the country on Doximity and US News and World Report for 2016. With the goal of training the next generation of leaders in molecular imaging, Johns Hopkins has created a combined residency training program in radiology and nuclear medicine.

Residents gain outstanding clinical training and participate in cutting-edge research programs that prioritize moving molecular imaging from laboratory-based studies to clinical translation of new imaging and theranostic agents and techniques.

Patient Care

Our team conducts a wide variety of procedures each year combining individualized care, specialty expertise and advanced technology.

For our diagnostic services, we offer state-of-the-art, precision imaging technology combined with expert interpretation to provide unparalleled patient care.

Discovery to innovative clinical care is the central tenet of modern academic medicine—the idea that scientists can develop research findings from the laboratory that can be converted into novel ways to treat patients. It is a cornerstone of the Division of Nuclear Medicine and Molecular Imaging at Johns Hopkins.
