Image artifacts from MR-based attenuation correction in dedicated PET/MR breast coil for PET/MR mammography
نویسندگان
چکیده
Materials and Methods Attenuation map of hybrid F-18 FDG PET/MR mammography in 38 patients diagnosed with invasive breast carcinoma were retrospectively inspected for artifacts. The artifacts were subdivided into 2 groups with minor (group A) and major artifacts (group B) on the basis of their severity. The impact of μ-map artifacts on PET interpretation was evaluated qualitatively via visual analysis as well as quantitatively by comparing SUVmax of breast cancer between PET/MR mammography and whole body PET/MR.

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 ...
متن کاملTowards integration of PET/MR hybrid imaging into radiation therapy treatment planning.
PURPOSE Multimodality imaging has become an important adjunct of state-of-the-art radiation therapy (RT) treatment planning. Recently, simultaneous PET/MR hybrid imaging has become clinically available and may also contribute to target volume delineation and biological individualization in RT planning. For integration of PET/MR hybrid imaging into RT treatment planning, compatible dedicated RT ...
متن کاملWhole-body hybrid imaging concept for the integration of PET/MR into radiation therapy treatment planning.
Modern radiation therapy (RT) treatment planning is based on multimodality imaging. With the recent availability of whole-body PET/MR hybrid imaging new opportunities arise to improve target volume delineation in RT treatment planning. This, however, requires dedicated RT equipment for reproducible patient positioning on the PET/MR system, which has to be compatible with MR and PET imaging. A p...
متن کاملMarkerless attenuation correction for carotid MRI surface receiver coils in combined PET/MR imaging.
The purpose of the study was to evaluate the effect of attenuation of MR coils on quantitative carotid PET/MR exams. Additionally, an automated attenuation correction method for flexible carotid MR coils was developed and evaluated. The attenuation of the carotid coil was measured by imaging a uniform water phantom injected with 37 MBq of 18F-FDG in a combined PET/MR scanner for 24 min with and...
متن کاملThe effect of limited MR field of view in MR/PET attenuation correction.
PURPOSE A critical question in the development of combined MR/PET scanners is whether MR can provide the tissue attenuation data required for PET reconstruction. Unfortunately, MR images are often unable to encompass the entire patient. The resulting truncation in the transverse plane leads to incomplete attenuation maps, causing artifacts in the reconstructed PET image. This article describes ...
