这e-Anatomy单元专门用于膝关节解剖,显示高分辨率 3T 核磁共振成像(多平面 PD-FS 和 T1 图像)上膝关节韧带、半月板、肌腱和其他结构的正常核磁共振成像外观。膝关节核磁共振成像(MRI)适用于各种临床情况,尤其是在最初的射线照相无法得出结论或需要进行详细的软组织评估时。美国放射学会(ACR)提供了针对不同膝关节疾病...
These researchers hypothesized that a substantial number of patients will show evidence of micro-instability after a sole decompression procedure. This study was a retrospective analysis of all cases of lumbar spinal stenosis treated at the Frankfurt University Clinic (Universitätsklinik Frankfurt) from...
While muscle biopsy provides valuable diagnostic information, it is an invasive procedure and may also cause collateral tissue damage. Clinical symptoms often fail to provide clear evidence in the early stages of the disease [35, 36]. Specifically, muscle MRI via Dixon water‒fat separation ...
In this paper, we introduce a self-supervised pretraining procedure using contrastive learning to improve the accuracy of undersampled DL MRI reconstruction. We use contrastive learning to transform the MRI image representations into a latent space that maximizes mutual information among different under...
To improve this model, accounting for spatial dependencies of PK pharmacokinetics, they used concatenated noisy time curves from first-order neighbourhood pixels in their expert DNNs and ensemble hypothesis DNN, collecting neighboring reconstructions before a boosting procedure produced the final clean ...
[75]. Looking closely at the dynamic T2mapping data obtained during baseline, pressure increase, and recovery, the investigators noted an expansion of the renal pelvis during the intervention (Fig.6). The increase in intrapelvic pressure during the procedure was strong enough to stretch the ...
tasks were generative, they were able to use the weights of both the encoder and decoder to initialize their downstream model. However, their method requires a separate diagnostic procedure, since it was trained on a private dataset consisting only of CT examinations from patients with COVID-19....
producing an EMI-free 1D MRI signal for that FE line. We applied this EMI cancellation procedure to all individual FE lines detected by MRI receive coil within MRI signal acquisition window before any signal averaging and subsequent image reconstruction (Fig.2d). Note that each layer within the...
What is the Vertiflex procedure for spinal stenosis? How long does appendix surgery take? Does autoimmune encephalitis show up on an MRI? What diagnostic tests are used to diagnose angina myocardial ischemia? Why is a brain MRI done to diagnose Lew...
procedure and allows a user to select steps in the workflow, wherein the circuit is configured to generate multi-dimensional visualizations using predefined data of the at least one tool and data from MRI images of the patient in substantially real time during the surgical procedure, and wherein...
