No Evidence for the Superiority of 3 Tesla Magnetic Resonance Imaging Over 1.5 Tesla Magnetic Resonance Imaging for Diagnosing Wrist Ligamentous Lesions: A Systematic Review and Meta-analysis.

Purpose: To determine the diagnostic accuracy of native magnetic resonance imaging (MRI) regarding different ligamentous lesions of the wrist and to analyze the influence of technical characteristics, such as field strength, application of fat saturation, 3-dimensional sequences, and wrist coils.

Methods: A systematic search was performed using MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases. Studies that were published before February 12, 2024, were included.

Load-induced increase in muscle activity during 30° abduction in patients with rotator cuff tears and control subjects.

Background: Rotator cuff muscles stabilise the glenohumeral joint and contribute to the initial abduction phase with other shoulder muscles. This study aimed to determine if the load-induced increase in shoulder muscle activity during a 30° abduction test is influenced by asymptomatic or symptomatic rotator cuff pathologies.

Materials And Methods: Twenty-five patients with unilateral rotator cuff tears (age, 64.

Rationale And Objectives: To assess the potential of 0.55T low-field MRI system in lumbar spine imaging with and without the use of additional advanced postprocessing techniques.

Materials And Methods: The lumbar spine of 14 volunteers (32.

Visual and quantitative assessment of hip implant-related metal artifacts at low field MRI: a phantom study comparing a 0.55-T system with 1.5-T and 3-T systems.

Background: To investigate hip implant-related metal artifacts on a 0.55-T system compared with 1.5-T and 3-T systems.

Load-Induced Glenohumeral Translation After Rotator Cuff Tears: Protocol for an In Vivo Study.

Background: Rotator cuff tears are a common shoulder injury, but they sometimes remain undiagnosed, as symptoms can be limited. Altered shoulder biomechanics can lead to secondary damage and degeneration. In biomechanical analyses, the shoulder (ie, the glenohumeral joint) is normally idealized as a ball-and-socket joint, even though a translation is often observed clinically.

Diagnostics of infrapatellar saphenous neuralgia-a reversible cause of chronic anteromedial pain following knee surgery.

Objectives: To evaluate the impact of diagnostic nerve block and ultrasound findings on therapeutic choices and predict the outcome after concomitant surgery in patients with suspected neuropathy of the infrapatellar branch of the saphenous nerve (IPBSN).

Methods: Fifty-five patients following knee surgery with suspicion of IPBSN neuralgia were retrospectively included. Ultrasound reports were assessed for neuroma and postsurgical scarring (yes/no).

Orthopaedic surgeons do not consult radiology reports. Fact or fiction?

Purpose: To find out how orthopaedic surgeons handle radiological reports and to identify ways to improve musculoskeletal radiology service and interdisciplinary communication.

Method: An anonymised 14-question online survey was distributed among 27 orthopaedic departments in German-speaking parts of Europe. It was available to trainees and consultants between 22/10/2020 and 05/06/2021.

AI-based detection and classification of distal radius fractures using low-effort data labeling: evaluation of applicability and effect of training set size.

Objectives: To evaluate the performance of a deep convolutional neural network (DCNN) in detecting and classifying distal radius fractures, metal, and cast on radiographs using labels based on radiology reports. The secondary aim was to evaluate the effect of the training set size on the algorithm's performance.

Methods: A total of 15,775 frontal and lateral radiographs, corresponding radiology reports, and a ResNet18 DCNN were used.

In vivo 3D tomography of the lumbar spine using a twin robotic X-ray system: quantitative and qualitative evaluation of the lumbar neural foramina in supine and upright position.

Objectives: Supine lumbar spine examinations underestimate body weight effects on neuroforaminal size. Therefore, our purpose was to evaluate size changes of the lumbar neuroforamina using supine and upright 3D tomography and to initially assess image quality compared with computed tomography (CT).

Methods: The lumbar spines were prospectively scanned in 48 patients in upright (3D tomographic twin robotic X-ray) and supine (30 with 3D tomography, 18 with CT) position.

MR variability of collagen meniscal implant remodelling in patients with good clinical outcome.

Purpose: Collagen meniscal implants (CMI) have variable imaging findings on MRI and it remains ambiguous, if alterations may be present in asymptomatic patients. The aim was, to evaluate MR morphological characteristics and volume of CMI in the early, mid- and long-term follow-up.

Methods: Fifty-seven patients (mean age, 43.

Dose-optimized computed tomography of the cervical spine in patients with shoulder pull-down: Is image quality comparable with a standard dose protocol in an emergency setting?

Purpose: Superimposing soft tissue and bony structures in computed tomography (CT) of the cervical spine (C-spine) is a limiting factor in optimizing radiation exposure maintaining an acceptable image quality. Therefore, we assessed image quality of dose-optimized (DO) C-spine CT in patients capable of shoulder pull-down in an emergency setting.

Methods And Materials: DO-CT (105mAs/120 kVp) of the C-spine in trauma settings was performed in patients with shoulder pull-down if C5 was not superimposed by soft tissue on the lateral topogram, otherwise standard-dose (SD)-CT (195 mAs/120 kVp) was performed.

Two positive tuberculosis cases in the late Nigrovits family, 18th century, Vác, Hungary.

Two mummies of the Hungarian mummy collection from Vác were the subjects of anthropological, paleopathological, radiological, paleomicrobiological, paleohistological and paleoproteomic studies. Both individuals belonged to the same family. The father, József Nigrovits (No 29), died at the age of 55 on the 11th of November 1793; his son, Antal Nigrovits (No 54), died on the 16th of July 1803, at the age of 22.

Effect of short-term unloading on T2 relaxation time in the lumbar intervertebral disc--in vivo magnetic resonance imaging study at 3.0 tesla.

Background Context: Diurnal changes in T2 values, indicative for changes in water content, have been reported in the lumbar intervertebral discs. However, data concerning short-term T2 changes are missing.

Purpose: The purpose of this study was to investigate the short-term effects of unloading on T2 values in lumbar intervertebral discs in vivo.

Quantitative T2 evaluation at 3.0T compared to morphological grading of the lumbar intervertebral disc: a standardized evaluation approach in patients with low back pain.

Background: The purpose of our investigation was to compare quantitative T2 relaxation time measurement evaluation of lumbar intervertebral discs with morphological grading in young to middle-aged patients with low back pain, using a standardized region-of-interest evaluation approach.

Patients And Methods: Three hundred thirty lumbar discs from 66 patients (mean age, 39 years) with low back pain were examined on a 3.0T MR unit.
