Three articles on developing observers for myocardial SPECT

Optimizing myocardial perfusion SPECT systems and methods for perfusion defect detection is highly significant. While mathematical observers exist for this purpose, they do not account for the variability in cardiac defect characteristics. In a series of articles, we investigate the causes for this issue and propose a novel mathematical observer that addresses this issue. X. […]

Young Investigator Award at SNMMI 2017

Dr. Abhinav Jha was awarded a Therapy Center for Excellence Young Investigator Award at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual meeting 2017. The award was for the paper titled “A no-gold-standard framework to evaluate FDG-PET tumor-segmentation methods on the task of measuring prognostic biomarkers for lung-cancer treatment” (link). We also had another […]

Two new journal articles on clinical quantitative PET

Metrics derived from quantitative PET, in particular intra-tumor heterogeneity, have sparked considerable interest as biomarkers for prognosis and predicting therapy response. In collaboration with radiologists at the Division of Nuclear Medicine, we have been investigating the role of intra-tumor heterogeneity in patients with different cancers. We recently published a couple of articles based on our research, […]

New paper on no-gold-standard evaluation in JMI Special section

Our paper on developing a no-gold-standard (NGS) technique to evaluate quantitative imaging methods with patient data in the absence of ground truth was accepted for publication in a special section of the Journal of Medical Imaging (link). This work was in collaboration with radiologists at the Johns Hopkins Division of Nuclear Medicine. We were interested […]

Three talks at SNMMI Annual Meeting 2017

We have had three talks accepted for presentation at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) Annual Meeting 2017. A. K. Jha, C. Marcus, R. Wray. R. Subramaniam, and E. Frey, “A no-gold-standard framework to evaluate FDG-PET tumor-segmentation methods on the task of measuring prognostic biomarkers for lung-cancer treatment”, Therapy Center Young Investigator Award, […]

New article on ADC estimation in diffusion MRI

Our paper on developing a statistical technique to estimate a single ADC value from a lesion using diffusion MRI was recently published in the journal Magnetic Resonance in Medicine. Especially exciting that the proposed method was rigorous, computationally fast, easy-to-implement, convenient-to-use, and more accurate than state-of-the-art methods in clinical settings! This work was in collaboration with […]
