The Relative Patlak Plot method, which was developed by our lab in 2018, is now made available on commercial PET scanners by a major manufacturer for clinical use. Compared to other methods, this method does not require the early-time blood input function and is therefore much easier to integrate with a clinical scan protocol for parametric imaging.
A clinical example of applying this technique for whole-body parametric imaging on a GE clinical PET scanner is shown in a recent Clinical Nuclear Medicine report by investigators from University Hospital Zurich and GE Healthcare.
We are delighted to announce that our Ph.D. candidate Yiran Wang successfully defended his Ph.D. thesis titled “Total-body PET Kinetic Modeling and Parametric Imaging with Applications to Lung Diseases and Beyond”. Yiran conducted this research under the joint supervision of Dr. Guobao Wang and Dr. Simon Cherry. The members of his dissertation committee also include Dr. Jinyi Qi.
Yiran’s dedication and hard work have culminated in this remarkable achievement. We are immensely proud of your accomplishments. Congratulations once again, Dr. Yiran Wang!
Ms. Anahita Tavakoli joins the lab as a new graduate student. She received her B.S. degree in Cognitive Science at the University of California, Davis. Anahita will be studying how the brain is changed in systemic disease using the total-body parametric PET technology. Welcome Anahita!
Dr. Kevin Chung won the Best Abstract Award in the postdoc group at the 2023 UC Davis Radiology Research Symposium for his very recent work on the parametric imaging of blood-brain barrier permeability of radiotracers using total-body dynamic PET. Congratulations Kevin!
