Dr. Martin A. Lodge is a Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science. He specializes in nuclear medicine and positron emission tomography (PET).

With over 30 years of experience in medical imaging physics, Dr. Lodge has an extensive background that includes PET, SPECT, CT, and MRI. In 1996 he received a Ph.D. in Medical Physics from the University of London where he worked on gamma camera collimator design and 3D reconstruction. He completed a research fellowship at the National Institutes of Health (Bethesda, MD) before taking a faculty position at the University of Maryland.

In 2006 Dr. Lodge joined the faculty at Johns Hopkins where he combines interests in research, clinical physics, and education. In his role as the director of clinical physics at the Johns Hopkins University PET Center, he has responsibility for technical aspects of all PET instrumentation, including PET and PET/CT scanners as well as associated equipment. He also has responsibility for Nuclear Medicine instrumentation including SPECT, SPECT/CT, and a range of other related probes.

Recent research interests have focused mainly on PET instrumentation, data processing, and image analysis. These have included data acquisition; quantitative image analysis; development of image-based biomarkers; statistical analysis of image data; optimizing clinical protocols; image artifacts; and quality assurance of PET/CT instrumentation. Recent national conference presentations include technical aspects of oncology PET standardized uptake value quantification including repeatability and practical imaging issues. In addition to research presentations at national meetings, he has been involved in workshops on PET/CT instrumentation and serves on the editorial board of the Journal of Nuclear Medicine. more

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
