  • MR Research Laboratory

    The MR Research Laboratory focuses on developing and applying nuclear magnetic resonance (NMR) techniques and on measuring energy metabolites and metabolic fluxes with phosphorous (31P) and proton (1H) MRS in patients with ischemia, infarction and heart failure.

    Specific studies include: Phosphorus MR studies of myocardial energy metabolism in human heart: We have used spatially localized phosphorus MR spectroscopy (MRS) to noninvasively measure high-energy phosphate metabolites such as ATP (adenosine triphosphate) and phosphocreatine (PCr) in the heart. The PCr/ATP ratio can change during stress-induced ischemia, and a protocol for stress-testing in the MR system has been developed which can detect the changes noninvasively in the anterior wall. Additionally, we've developed methods for noninvasively measuring the creatine kinase (CK) ATP energy supply and used it to measure the CK ATP energy supply in the healthy heart at rest and exercise, in human myocardial infarction, and in ...human heart failure.

    Interventional MRI technology: We are developing an RF dosimeter that measures incident-specific absorption rates applied during MRI independent of the scanner and developing MRI-safe internal detectors for higher field use. Outcomes of this research include the "MRI endoscope" that provides real-time, high-resolution views of vessel anatomy and a radiometric approach to detect any local heating associated with the device.

  • Weiss Lab

    The Weiss Lab, which features a multi-disciplinary team at Johns Hopkins as well as at Cedars Sinai Medical Center in Los Angeles, is dedicated to identifying the most important clinical, genetic, structural, contractile and metabolic causes of sudden cardiac death as well as the means to reverse the underlying pathology and lower risk.

    Current projects include research into energy metabolism in human heart failure and creatine kinase metabolism in animal models of heart failure.

    Robert G. Weiss, MD, is professor of medicine, Radiology and Radiological Science, at the Johns Hopkins University.
