Journal ArticleDOI
Perfusion imaging by a flow-sensitive alternating inversion recovery (FAIR) technique: application to functional brain imaging.
Seong-Gi Kim,Nikolaos V. Tsekos +1 more
TL;DR: A newly developed flow‐sensitive alternating inversion recovery (FAIR) technique was used to obtain perfusion‐weighted images and consequently to measure cerebral blood flow (CBF), suggesting that the oxygen consumption increase couples with the CBF change completely.
Journal ArticleDOI
Magnetic resonance-compatible robotic and mechatronics systems for image-guided interventions and rehabilitation: a review study.
TL;DR: An overview of the motivation, advantages, technical challenges, and existing prototypes for MR-compatible robotic/mechatronic devices is given.
Patent
MRI-guided interventional mammary procedures
TL;DR: In this paper, the authors used contrast enhanced magnetic resonance imaging (MRI) and MR-guided subcutaneous core biopsy as a robust approach for the diagnosis and treatment of breast cancer.
Journal ArticleDOI
Design of an MRI-compatible robotic stereotactic device for minimally invasive interventions in the breast.
Blake Timothy Larson,Arthur G. Erdman,Nikolaos V. Tsekos,Essa Yacoub,Panagiotis V. Tsekos,Ioannis G. Koutlas +5 more
TL;DR: The objective of this work was to develop a robotic device to perform biopsy and therapeutic interventions in the breast with real-time magnetic resonance imaging (MRI) guidance, and compatibility of the device within the MR environment was successfully tested on a 4 Tesla MR human scanner.
Concepts of myocardial perfusion imaging in magnetic resonance imaging.
N. Wilke,Michael Jerosch-Herold,A. E. Stillman,Keith Kroll,Nikolaos V. Tsekos,H. Merkle,Todd B. Parrish,Xiaoping Hu,Y. Wang,James B. Bassingthwaighte +9 more
TL;DR: Preliminary results suggest that quantitative assessment of myocardial perfusion is feasible, but additional studies should provide further confidence for this novel MR approach.
