Technical Challenges & Opportunities of PET/MR: An Overview

Following PET/CT, PET/MR is the newest diagnostic whole-body hybrid imaging modality. Simultaneous PET and MR data acquisition requires novel technical solutions and offers new diagnostic opportunities. Attenuation correction (AC) and motion correction (MC) of PET data are current hot topics in PET/MR hybrid imaging research. The added diagnostic value of PET/MR in whole-body imaging is current...

Comparison of state-of-the-art atlas-based bone segmentation approaches from brain MR images for MR-only radiation planning and PET/MR attenuation correction

Introduction: Magnetic Resonance (MR) imaging has emerged as a valuable tool in radiation treatment (RT) planning as well as Positron Emission Tomography (PET) imaging owing to its superior soft-tissue contrast. Due to the fact that there is no direct transformation from voxel intensity in MR images into electron density, itchr('39')s crucial to generate a pseudo-CT (Computed Tomography) image ...

7T clinical cardiovascular MR imaging: initial experience

Background Recently, high-field 7T MR imaging was introduced. The higher field-strength has potential advantages, mainly related to increased signal-to-noise-ratio. One of the potentially exciting applications may be cardiovascular MR imaging. Cardiovascular MRI requires robust correction for heart motion, breathing motion and correction of field inhomogeneities. Therefore, cardiovascular imagi...
