To compare the image quality and diagnostic performance of conventional motion-corrected periodically rotated overlapping parallel line with enhanced reconstruction (PROPELLER) MRI sequences post-processed PROPELLER using deep learning-based (DL) reconstructions.In this prospective study 30 patients, (19 min 18 s) accelerated (7 16 technique were acquired. Accelerated DL. The confidence qualitatively assessed by 2 readers a 5-point Likert scale. Analysis pathological findings cartilage,...
The study aims to evaluate the diagnostic performance of deep learning-based reconstruction method (DLRecon) in 3D MR neurography for assessment brachial and lumbosacral plexus.Thirty-five exams (18 17 plexus) 34 patients undergoing routine clinical at 1.5 T were retrospectively included (mean age: 49 ± 12 years, 15 female). Coronal T2-weighted short tau inversion recovery fast spin echo with variable flip angle sequences covering plexial nerves on both sides obtained as part standard...
Prospective.To investigate the influence of paraspinal fatty muscle infiltration (FMI) and cumulative lumbar spine degeneration as assessed by magnetic resonance imaging on long-term clinical outcome measures in patients with spinal canal stenosis (LSCS) Lumbar Stenosis Outcome Study (LSOS) cohort.Past studies have tried to establish correlations morphologic findings LSCS endpoints. However, impact FMI overall load has not been examined yet.Patients from LSOS cohort moderate severe were...
Abstract Objectives To generate pseudo-CT (pCT) images of the pelvis from zero echo time (ZTE) MR sequences and compare them to conventional CT. Methods Ninety-one patients were prospectively scanned with CT MRI including ZTE pelvis. Eleven image volumes excluded due implants severe B1 field inhomogeneity. Out 80 data sets, 60 used train update a deep learning (DL) model for pCT synthesis while remaining 20 cases selected as an evaluation cohort. assessed qualitatively quantitatively by two...
To assess the impact on bone depiction quality by decreasing number of radial acquisitions (RA) a UTE MR imaging sequence in MRONJ.UTE sequences using pointwise encoding time reduction with RA (PETRA) 60'000, 30'000 and 10'000 were acquired 16 patients MRONJ healthy volunteers. Blinded readout sessions performed two radiologists. Qualitative analysis compared detection osteolytic lesions productive bony changes PETRA MRONJ. Quantitative assessed differences image artifacts, contrast-to-noise...
The palmaris longus is a superficial muscle located on the volar side of forearm. It usually arises from medial epicondyle humerus and inserts into palmar aponeurosis wrist. However, one most variable muscles in human body. frequent anatomic variation complete agenesis, which found up to 25% population.9,12 Other variations include reversed, duplicated, bifid, or hypertrophied muscles, can be clinical significance by causing effort-related pain with without median ulnar nerve...
To assess whether two-point Dixon (TPD) MRI, true fast imaging with steady-state free precession (TRUFI) MRI and non-contrast-enhanced CT (NECT) can accurately measure muscle fat fraction (FF) in the autochthonous back muscles (AM) psoas (PM) compared to multi-point (MPD) MRI.29 oncological patients who received including MPD, TPD NECT a period of three months were analyzed retrospectively. A sub-cohort 16 additionally underwent TRUFI included sub-analysis. Region interest (ROI) measurements...
