Proceedings ArticleDOI
Correlating Acupuncture fMRI in the Human Brainstem with Heart Rate Variability
Vitaly Napadow,Rupali P. Dhond,Patrick L. Purdon,Norman W. Kettner,Nikos Makris,Kenneth K. Kwong,Kathleen K.S. Hui +6 more
TL;DR: FMRI activity in the hypothalamus, the dorsal raphe nucleus, the periaqueductal gray, and the rostroventral medulla showed significant correlation with LF/HF ratio calculated from simultaneous HRV data, suggesting insight into connections between acupuncture modulation of the autonomic nervous system and neuroprocessing.
Journal ArticleDOI
Dynamic signal intensity changes in liver with superparamagnetic MR contrast agents.
Peter Reimer,Kenneth K. Kwong,Robert M. Weisskoff,Mark S. Cohen,Thomas J. Brady,Ralph Weissleder +5 more
TL;DR: Monitoring liver SI over time with echo‐planar imaging may provide a better understanding of the kinetics of the growing number of MR contrast agents and allow optimization of imaging protocols to exploit peak enhancement.
Journal ArticleDOI
Applications of similarity mapping in dynamic MRI
Jadwiga Rogowska,K. Preston,George J. Hunter,Leena Hamberg,Kenneth K. Kwong,O. Salonen,Gerald L. Wolf +6 more
TL;DR: The authors describe the abilities of similarity mapping to identify different image structures present in several dynamic MRI datasets with potential clinical value and demonstrate that similarity mapping technique has been successful in identifying the following structures.
Journal Article
[Echo-planar imaging of the brain].
TL;DR: The clinical utility of echoplanar techniques in MRI of the brain is discussed, and comparison of high-resolution EPI with SE/turbo-SE shows high image quality of EPI in the supratentorial brain.
Journal ArticleDOI
In vivo study of microbubbles as an MR susceptibility contrast agent
Kelvin K. Wong,Ing-Jye Huang,Ing-Jye Huang,Young Ro Kim,Haiying Tang,Edward Yang,Kenneth K. Kwong,Ed X. Wu,Ed X. Wu +8 more
TL;DR: Eight of the 16 rats studied showed no susceptibility enhancement, probably attributable to the intravascular microbubble growth due to transmural CO2 supersaturation in the cecum and colon in small animals that causes microbubbles aggregation and trapping in the inferior vena cava.
