MR fingerprinting with simultaneous T1, T2, and fat signal fraction estimation with integrated B0 correction reduces bias in water T1 and T2 estimates

Autor: Jason Ostenson, E. Brian Welch, Bruce M. Damon

Publikováno v: Magnetic Resonance Imaging. 60:7-19

Purpose MR fingerprinting (MRF) sequences permit efficient T1 and T2 estimation in cranial and extracranial regions, but these areas may include substantial fat signals that bias T1 and T2 estimates. MRI fat signal fraction estimation is also a topic

Slice-selective extended phase graphs in gradient-crushed, transient-state free precession sequences: An application to MR fingerprinting

Autor: Jason Ostenson, Mark D. Does, David S. Smith, Bruce M. Damon

Publikováno v: Magn Reson Med

PURPOSE: Slice-selective, gradient-crushed, transient-state sequences such as those used in magnetic resonance fingerprinting (MRF) relaxometry are sensitive to slice profile effects. While balanced steady-state free precession MRF profile effects ha

Voxelwise analysis of simultaneously acquired and spatially correlated 18 F-fluorodeoxyglucose (FDG)-PET and intravoxel incoherent motion metrics in breast cancer

Publikováno v: Magnetic Resonance in Medicine. 78:1147-1156

Purpose Diffusion-weighted imaging (DWI) and 18F-fluorodeoxyglucose–positron emission tomography (18F-FDG–PET) independently correlate with malignancy in breast cancer, but the relationship between their structural and metabolic metrics is not co

Multi-Frequency Interpolation in Spiral Magnetic Resonance Fingerprinting for Correction of Off-Resonance Blurring

Autor: E. Brian Welch, Jason Ostenson, Nicholas R. Zwart, Ryan K. Robison

Magnetic resonance fingerprinting (MRF) pulse sequences often employ spiral trajectories for data readout. Spiral k-space acquisitions are vulnerable to blurring in the spatial domain in the presence of static field off-resonance. This work describes

The effect of metallic tracheal stents on radiation dose in the airway and surrounding tissues

Autor: Syed S. Razi, David Y. Lee, Koji Park, F.Y. Bhora, Anudh K. Jain, Jason Ostenson, Gary S. Schwartz, Jordan R. Sasson, F. Trichter, Andrew Evans

Publikováno v: Journal of Surgical Research. 189:1-6

Background Metallic airway stents are often used in the management of central airway malignancies. The presence of a metallic foreign body may affect radiation dose in tissue. We studied the effect of a metallic airway stent on radiation dose deliver

Comparison of CT and MR-CT fusion for prostate post-implant dosimetry

Autor: Alexander Pevsner, Ronald D. Ennis, Iddo K. Wernick, Jason Ostenson, Kristina L. Maletz, Alexander Kagen

Publikováno v: International journal of radiation oncology, biology, physics. 82(5)

The use of T2 MR for postimplant dosimetry (PID) after prostate brachytherapy allows more anatomically accurate and precise contouring but does not readily permit seed identification. We developed a reproducible technique for performing MR-CT fusion
