Journal ArticleDOI
Impact of image preprocessing methods on reproducibility of radiomic features in multimodal magnetic resonance imaging in glioblastoma.
TL;DR: The preliminary findings imply that preprocessing sequences can also have a significant impact on the robustness and reproducibility of mMRI‐based radiomics features and identification of generalizable and consistent preprocessing algorithms is a pivotal step before imposing radiomics biomarkers into the clinic for GBM patients.
Journal ArticleDOI
Comparing the dosimetric characteristics of the electron beam from dedicated intraoperative and conventional radiotherapy accelerators.
Hamid Reza Baghani,Seyed Mahmoud Reza Aghamiri,Seyed Rabi Mahdavi,Mohammad Esmail Akbari,Hamid Reza Mirzaei +4 more
TL;DR: It can be concluded that dosimetric characteristics of intraoperative electron beam are substantially different from those of conventional clinical electron beam, which makes it a useful tool for intraoperative radiotherapy purposes.
Journal ArticleDOI
Optical and MRI investigations of an optimized acrylamide-based polymer gel dosimeter
TL;DR: The R2-sensitivity of polymer gel was improved by a factor of more than 2.6 in respect of the previously reported PAGAT polymer gel, and a new optical parameter, area under the absorbance spectrum (AUS), was investigated.
Journal ArticleDOI
Production of glass microspheres comprising 90Y and 177Lu for treating of hepatic tumors with SPECT imaging capabilities
Hosein Poorbaygi,Seyed Mahmoud Reza Aghamiri,Shahab Sheibani,Alireza Kamali-Asl,Elham Mohagheghpoor +4 more
TL;DR: Results of the neutron activation indicate that such a combination of glass, microspheres allow bio-distribution studies by SPECT imaging with high resolution.
Journal ArticleDOI
Is metal artefact reduction mandatory in cardiac PET/CT imaging in the presence of pacemaker and implantable cardioverter defibrillator leads?
Pardis Ghafarian,Seyed Mahmoud Reza Aghamiri,Mohammad Reza Ay,Arman Rahmim,Thomas H. Schindler,Osman Ratib,Habib Zaidi +6 more
TL;DR: Cardiac PET images corrected for attenuation using CTAC in the presence of metallic leads can be interpreted without correction for metal artefacts, and the MAR algorithm was able to effectively improve the quality of μ-maps.
