Article Synopsis
- The study explores a new deep learning (DL)-based MRI reconstruction method, VIBE-DixonDL, aimed at reducing breath-hold times and enhancing image quality in patients with pancreatic conditions.
- Conducted from January to September 2023, it involved 32 participants who underwent two types of MRI scans to compare the conventional method against the DL approach.
- Results showed a substantial 52% reduction in breath-hold time and improved image clarity, helping detect pancreatic lesions better and increasing overall diagnostic confidence.
Background: Neck computed tomography (NCT) is essential for diagnosing suspected neck tumors and abscesses, but radiation exposure can be an issue. In conventional reconstruction techniques, limiting radiation dose comes at the cost of diminished diagnostic accuracy. Therefore, this study aimed to evaluate the effects of an AI-based denoising post-processing software solution in low-dose neck computer tomography.

(2) Methods: Patients, who underwent tumor resection between 2009 and 2019 and received a pre- and postoperative MRI, were included in this retrospective single-center study. Measurement of residual disease (RD) was performed using standardized criteria.

Methods: From our prospective observational PET/MRI study, a subcohort of patients diagnosed with NB with both baseline imaging and post-chemotherapy imaging was further investigated. After registration and tumor segmentation, metabolic and functional tumor volumes were calculated from the ADC and SUV values using dedicated software allowing for voxel-wise analysis.
Murine norovirus (MNV) is a positive-sense, plus-stranded RNA virus in the Caliciviridae family. Viruses in this family replicate in the intestine and are transmitted by the fecal-oral route. MNV is related to the human noroviruses, which cause the majority of nonbacterial gastroenteritis worldwide.
