without contrast material 72149 Magnetic resonance (e.g., proton) imaging, spinal canal and contents, lumbar; with contrast material 72158 Magnetic resonance (e.g., proton) imaging, spinal canal and contents, lumbar; without contrast material followed by contrast material and further sequences 1....
The results are often good, although some patients develop prolonged morbidity with postoperative pain and stiffness. The main aim of the present study was to analyze the reaction of the joint capsule 3 months after subacromial decompression using MRI without contrast. We also wanted to study if ...
Magnetic resonance imaging (MRI) is a highly sensitive and specific imaging technique that yields comprehensive images of the structure, function, and composition of tissues in the body.1Balasubramanya R, Selvarajan SK. Lumbar Spine Imaging. [Updated 2022 Mar 9]. In: StatPearls [Internet]. Treasu...

Compared with conventional imaging, in contrast, dynamic contrast-enhanced magnetic resonance imaging can also better assess the relationship between changes in lumbar spine perfusion, disc degeneration, and endplate perfusion at different stages. Key words: bone; MRI; dynamic contrast enhancement; ...
This study evaluated the clinical application and cost effectiveness of accelerated 3D T2 sequences of the lumbar spine.Prospective, cross-sectional, observational.Twenty healthy volunteers and 10 patients.A 3D T2 TSE sequence, identical 3D sequences with three different parallel imaging and CS ...
Models using LBP features provided better results, with macro-average AUC values of 0.767 and 0.714, accuracy of 61.2 and 61.4%, and macro-average recall of 61.9 and 59.8%, in the LDA and k-NN classifiers, respectively. In contrast, the accuracies of radiomics models distinguishing between ...
In the first, Case number 1 5, in whom injury was in the lumbar region, the MRI revealed odontoid fracture with the fractured fragments causing compression of the cord. This lesion had not been visualised by conventional radiographs at the time of initial injury. This case is discussed ...
The aim of this study was therefore to explore the capabilities of an advanced deep learning-based image reconstruction algorithm in terms of image quality and image acquisition time in lumbar spine imaging at 0.55 T compared with established image reconstruction techniques already used in clinical...
Nearly nothing is known about the consequences of ultra-long-distance running on knee cartilage. In this mobile MRI field study, we analysed the biochemical effects of a 4,486 km transcontinental multistage ultra-marathon on femorotibial joint (FTJ) c
