Biosketch

After graduating from nuclear medicine residency at the Medical University of South Carolina as a chief resident in 2012, Dr. Ahlman joined the NIH through the Imaging Sciences Training Program in the same year. Prior to residency, he received his medical degree at the Georgia Health Sciences University in 2008, preceded by a bachelor's degree in biology from Columbus State University in 2004.

As lab manager for the Director of Radiology and Imaging Sciences, Dr. David Bluemke, Dr. Ahlman is coordinating the development of highly advanced techniques to allow for motion correction of MR-PET, as it is applied to preclinical diagnosis of atherosclerosis and heart failure. This endeavor brings together experts from multiple disciplines from across the globe, including researchers at Harvard, Cedars-Sinai, and Johns Hopkins University. Board certified in nuclear medicine and cardiovascular computed tomography, his clinical practice in radiology at the Clinical Center synergizes with his research in novel applications of IV contrast dynamics, PET, CT, and MR physics. These areas of expertise have installed his involvement in over 8 protocols at the NIH over the last several years. Most recently, the larger component of his research has been focused on vascular PET in diseases such as atherosclerosis, vasculitis, psoriasis, and chronic granulomatous disease.

Dr. Ahlman continues his academic career within the NIH as a Staff Clinician in Radiology, and is frequently a guest speaker at academic institutions and within the Society of Nuclear Medicine and Molecular Imaging. In addition to his broad clinical and research experience in nuclear cardiology, neurology, and oncology, a summary of specific research interests is below:

  • Genomic imaging
  • Confounding genetic, physiologic, or physical parameters affecting quantification and clinical interpretation of PET
  • Advanced IV and PO contrast techniques in PET-CT and PET-MR
  • PET and SPECT attenuation correction
  • Inter-modality image fusion and voxel-wise analysis
  • Machine learning for image interpretation
