Denoising low-field MR images with a deep learning algorithm based on simulated data from easily accessible open-source software.

In this study, we introduce a denoising method aimed at improving the contrast ratio in low-field MRI (LFMRI) using an advanced 3D deep convolutional residual network model. Our approach employs synthetic brain imaging datasets that closely mimic the contrast and noise characteristics of LFMRI scans, addressing the limitation of available in-vivo LFMRI datasets for training deep learning models. In the simulation data, the Relative Contrast Ratio (RCR) increased, and similar improvements were observed in the in-vivo data across different imaging conditions.

: An uncommon cause for a common hospital admission.

Common organisms associated with community-acquired pneumonia include , , and . Pneumonia can rarely be caused by an organism such as , as in our case. This organism belongs to the Mitis group within the and typically coexists with humans in the oral cavity.

Not just a simple sore throat.

The presentation of a 'sore throat' is common and often requires only symptomatic treatment. This is the case of a 20-year-old female who presented with persistent symptoms of a sore throat. On admission she had raised inflammatory markers and a subsequent blood culture demonstrated a fusobacterium necrophorum and arcanobacterium haemolyticum bacteraemia.
