(2024), (Campbell Washburn et al., 2019) due to increased safety and lower manufacturing and maintenance cost and consequently improving the accessibility of MRI for clinical purposes (Arnold et al., |
| 15 | +2023). The reduced field strength leads to a reduced signal and change in T1 relaxation times and therefore different contrast and signal to noise as 1.5T and 3T systems.<br>MRI is often used for diagnosing and monitoring brain tumors, lesions, and disorders such as neurodegenerative diseases. Especially for the last afflictions gray matter (GM) and white matter (WM) volume are interesting markers due to the atrophy associated with these diseases. Automatic segmentation models including Adaptive Maximum A Posteriori (MAP) segmentation (Rajapakse et al., 1997) and partial volume estimation (PVE) (Tohka et al., 2004) are well established models that are used by applications such as CAT12 to estimate GM and WM volumes.<br>In this work we study the quality of T1 weighted based brain segmentations at 0.6T in the context of brain volume measurements in healthy volunteers. We compare segmentations from 0.6T and 1.5T and study how noise suppression by deep learning based reconstruction as provided by the vendor might affect these.}, |

| 30 | + abstract = {Fluid-Attenuated Inversion Recovery (FLAIR) images are an important part of clinical brain protocols, especially due to the excellent contrast for diagnosing lesions, edema, etc. (Campbell-Washburn et al., 2019). Mid field MR scanners (0.1T-1T) provide a more accessible and affordable option for clinical use compared to high-field scanners (Arnold et al., 2023). However, lower field strength often produces lower-quality FLAIR images due to longer T1 relaxation time and lower signal to noise ratio (Lavrova et al., 2024). Moreover, from our initial tests with a 0.6T MRI-scanner, we noticed that the relative drop in quality of these images compared to 1.5T was much higher for FLAIR than for example T2W images, which could limit their diagnostic value.<br>This project aims to address this issue by applying a content/style-based plug-and-play reconstruction framework PnP-MUNIT (Rao et al., 2024) to guide the reconstruction of FLAIR images using information from T2-weighted scans, with the goal of improving image quality and reducing the scan time. In this work we assess this concept using data from a 3T scanner and adapt it for 0.6T data, applying the content/style model to the lower field strength in a zero-shot manner without any fine-tuning.}, |
