Real-time magnetic resonance imaging of laser heat deposition in tissue.
Alan R. Bleier,Ferenc A. Jolesz,Mark S. Cohen,Robert M. Weisskoff,Julianne J. Dalcanton,Nobuya Higuchi,David A. Feinberg,Bruce R. Rosen,Robert C. McKinstry,Stephen G. Hushek +9 more
TL;DR: Images of phantom materials and normal rabbit brain tissue in vivo, acquired in 150 ms, every 2 s, clearly showed the dynamics of temperature‐related signal intensity changes in the regions irradiated by the laser.

Tissue temperature monitoring for thermal interventional therapy: comparison of T1-weighted MR sequences.
TL;DR: Methods introduced to evaluate temperature sensitivity and resolution should prove useful in selecting appropriate MR protocols for monitoring thermal treatment modalities such as interstitial laser therapy, focused ultrasound therapy, or radio‐frequency heating.

MRI of laser-induced interstitial thermal injury in an in vivo animal liver model with histologic correlation.
Paul R. Morrison,Ferenc A. Jolesz,Daniel Charous,Robert V. Mulkern,Stephen G. Hushek,Randall Margolis,Marvin P. Fried +6 more
TL;DR: Monitoring of LITT in vivo in rabbit liver found lesions had hyperintense margins that were brighter than surrounding normal tissue and mapped to tissue necrosis characterized by the presence of thermally damaged ghost red blood cells amid generally normal hepatocytes.

MR systems for MRI-guided interventions
Stephen G. Hushek,Alastair J. Martin,Michael Steckner,Elyakim Bosak,J. Debbins,Walter Kucharzyk +5 more
TL;DR: The various systems that research groups and vendors have designed to meet the requirements of interventional MR are discussed and possible solutions to those requirements that have not yet been met are suggested.

Dynamic T1‐weighted magnetic resonance imaging of interstitial laser photocoagulation in the liver: Observations on in vivo temperature sensitivity
Marvin P. Fried,Paul R. Morrison,Stephen G. Hushek,Gilberto A. Kernahan,Ferenc A. Jolesz,Ferenc A. Jolesz +5 more
TL;DR: MRI's potential to monitor interstitial laser photocoagulation (ILP) has been previously demonstrated and is further tested here with improved spatial and temporal resolution.
