PET attenuation correction using synthetic CT from ultrashort echo-time MR imaging.
UNLABELLED Integrated PET/MR systems are becoming increasingly popular in clinical and research applications. Quantitative PET reconstruction requires correction for γ-photon attenuations using an attenuation coefficient map (μ map) that is a measure of the electron density. One challenge of PET/MR, in contrast to PET/CT, lies in the accurate computation of μ maps. Unlike CT, MR imaging measure...
متن کاملAnatomic evaluation of 3-dimensional ultrashort-echo-time bone maps for PET/MR attenuation correction.
UNLABELLED Ultrashort-echo-time (UTE) sequences have been proposed in the past for MR-based attenuation correction of PET data, because of their ability to image cortical bone. In the present work we assessed the limitations of dual-echo UTE imaging for bone segmentation in head and neck imaging. Sequentially acquired MR and PET/CT clinical data were used for this purpose. METHODS Twenty pati...
متن کاملMRI-based attenuation correction for PET/MRI using ultrashort echo time sequences.
UNLABELLED One of the challenges in PET/MRI is the derivation of an attenuation map to correct the PET image for attenuation. Different methods have been suggested for deriving the attenuation map from an MR image. Because the low signal intensity of cortical bone on images acquired with conventional MRI sequences makes it difficult to detect this tissue type, these methods rely on some sort of...
متن کاملMR-based attenuation correction using ultrashort-echo-time pulse sequences in dementia patients.
UNLABELLED Attenuation correction (AC) is a critical requirement for quantitative PET reconstruction. Accounting for bone information in the attenuation map (μ map) is of paramount importance for accurate brain PET quantification. However, to measure the signal from bone structures represents a challenging task in MR. Recent (18)F-FDG PET/MR studies showed quantitative bias for the assessment o...
متن کاملEstimation of fetal absorbed dose from low-dose attenuation-correction CT in PET / CT imaging by using the Body Builder Phantom
One of the methods of studying the physiology and metabolism of important tissues such as the heart, brain and cancer tumors is the use of PET/CT System. A small number of patients are pregnant women who undergo a PET/CT scan due to lack of knowledge about pregnancy or due to dire clinical need. The final dose received by the fetus is based on three factors: the absorbed dose of the fetal tissu...
