Image Quality of 1.5 T MRI Using Dual‐Type Deep Learning Reconstruction for Pancreatic Cystic Lesions: An Exploratory Comparison With Conventional 3 T MRI Without Deep Learning Reconstruction

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dual‐type deep learning reconstruction (DLR) may improve the pancreatic MRI image quality; however, the effects of different DLR strengths at 1.5 T compared with the conventional 1.5 T and 3 T MRI without DLR remain unclear. Purpose To evaluate the image quality of 1.5 T MRI reconstructed with different DLR strengths for pancreatic ...

Impact of Dapagliflozin on MRI‐Derived Epicardial Adipose Tissue: Secondary Imaging Analysis of a Randomized Trial

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Epicardial adipose tissue (EAT) is a metabolically active fat depot associated with cardiovascular risk and represents a modifiable imaging biomarker. Studies have shown that sodium–glucose cotransporter‐2 (SGLT2) inhibitors reduce EAT thickness in patients with type 2 diabetes mellitus (T2DM). However, it is unclear whether this is

An Inline‐Integrable Image Restoration Model With ROI Fine‐Tuning and Slice‐to‐Volume Reconstruction for Accelerated Whole‐Brain Vessel Wall Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a vessel wall imaging (VWI)‐dedicated image restoration model enabling high‐resolution whole‐brain VWI in under 6 min. Methods A transformer‐based 2.5D model was trained in a supervised manner to enhance the image quality of CAIPIRINHA 2 × 2‐accelerated VWI acquisitions to a level comparable to that of GRAPPA twofold ...

Self‐Correction of B0 Drift and Trajectory Error in Alternating Unbalanced SSFP‐FID and SSFP‐ECHO (AUSFIDE)‐Based 3D Transverse Relaxometry of the Human Brain

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The alternating unbalanced SSFP (AUSFIDE) pulse sequence, which consists of multi‐echo trains of SSFP‐FID and SSFP‐ECHO modules, enables rapid estimation of R2 and R2′, but is prone to errors from temporal drift of the main magnetic field (B0) and k‐space trajectory mismatch.

Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

PROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.
