Positron Emission Tomography
PET is the most advanced nuclear imaging technique. It provides superior resolution and allows for absolute quantification of biologic mechanisms. It is a specialty of Johns Hopkins, which now offers PET for clinical assessment of myocardial perfusion and viability.
A complete perfusion study with the FDA approved very short lived tracer Rubidium-82 (75 s half-life) is performed in 60 minutes and is especially useful in challenging cases (e.g. equivocal SPECT, morbid obesity).
PET cardiac studies are reimbursed by Medicare and most insurance plans.
PET/CT and SPECT/CT Hybrid Systems
Recent technical advances have resulted in the combination of SPECT or PET scanners together with X-ray computed tomography (CT) in a single camera system. These hybrid systems yield maximum information and a complete set of pictures with a single noninvasive imaging study, by integrating functional information from nuclear imaging with morphologic information for CT.
Cardiovascular Nuclear Medicine
To continue its longstanding history of leadership in biomedical imaging, the Division of Nuclear Medicine at Johns Hopkins Medical Institutions has recently enhanced and expanded its services with the most advanced nuclear imaging systems and additional expert clinicians. The novel SPECT/CT and PET/CT scanners now incorporate the most modern PET and SPECT detection methods with state of the art multi-slice X-ray CT to increase diagnostic accuracy.
Cardiac imaging at the highest possible standard is thus available for the workup of suspect or known cardiovascular disease. This program is continuously updated through incoming developments from our cardiovascular research program.
