This paper presents a large publicly available multi-center lumbar spine magnetic resonance imaging (MRI) dataset with reference segmentations of vertebrae, intervertebral discs (IVDs), and spinal canal. The dataset includes 447 sagittal T1 and T2 MRI series from 218 patients with a history of low...
in which the X axis represents different signal intensities, and the Y axis represents the corresponding number of pixels. A two-peak distribution has been analyzed in healthy IVD from MRI, because the sharpness of the boundary between the NP and the AF can be well characterized...
In contrast, modern 0.55 T MRI systems incorporate advances and technical innovations in coil design, parallel imaging techniques, and especially image post-processing algorithms, all adopted from higher-field-strength MRI scanners [7]. Current studies show that the image quality for musculoskeletal...
While the high resolution and high contrast CThas been the modality of choice, MRI can capture both bone andsoft tissue without the ionizing radiation of CT albeit longer acquisition time. The critical tradeoff between contrast qualityand acquisition time has motivated 'thick slice MRI', which ...
In a recent study21, a longer duration of type 2 diabetes was suggested to be a risk factor for lumbar disc degeneration, as shown by a cross-sectional study using magnetic resonance imaging (MRI), a result which is in line with our findings. Because diabetic complication is highly related...
That is why the answers to the following questions are important: (1) which part of the back (neck or lumbar spine) is more likely to be painful in military pilots as a result of high G-force, and (2) what intervention methods do pilots use as countermeasures for back pain resulting ...
The gradient echo imaging data were processed online using the fat quantification routine of the MRI vendor (Philips Healthcare, Best, The Netherlands). After phase error correction, complex-based water–fat decomposition was performed using a precalibrated seven-peak fat spectrum model with a single...
The findings of that study inspired us to develop indication criteria for the use of the lateral approach in lumbar spine surgery using preoperative magnetic resonance imaging (MRI) in the axial view. We also modified the conventional lateral approach with respect to the position of entry into ...
In contrast, the most common reason for LTSA and DP among individuals without diagnosed LBP was mental disorders (35% of all LTSA and 44% of all DP). Notably, the proportion of individuals being on LTSA or DP due to disorders of the nervous system, symptoms, signs and abnormal clinical...
