MRI lesions of the spine in patients with axial spondyloarthritis: an update of lesion definitions and validation by the ASAS MRI working groupInflammationMagnetic Resonance ImagingSpondylitis, AnkylosingObjectives:Spinal MRI is used to visualise lesions associated with axial spondyloarthritis (axSpA). The ...
giant cells, histiocytes (foam cells),hemosiderin depositionand fibrous tissue are seen within the lesion. PVNS can be seen in the intraarticular location or extra-articular peri-
lesion is defined as tDV and mean ADC value of the area is calculated. The software is particularly useful for processing multiple and large lesions, such as multiple metastatic lesions detected by whole-body DWI. Thus, it has been adopted for evaluating the therapeutic effect of whole-body me...
(3) Whether the primary lesion is solid or cystic-solid, the solid component appears isointense or slightly hypointense on T1WI, exhibits significantly high signal on DWI, has a notably low ADC value, and shows enhancement lower than the myometrium. Internal features may include hemorrhage or ...
Based on previous studies, [22–23] tumor morphology was selected and evaluated: (1) Tumor location was determined by the lesion center and divided into two groups: supratentorial or infratentorial, peripheral or median parenchyma (basal ganglia, thalamus, brainstem, and cerebellum). (2) The max...
Predominantly afflicting individuals aged 45 and above, this ailment is commonly labeled as a “wear and tear” joint disorder, targeting joints such as the knee, hand, hips, and spine. Osteoarthritis symptoms typically increase gradually, contributing to the deterioration of articular cartilage. ...
(C) The STIR sequence also shows a localized hyperintensity with slightly minor dimension. With regard to the size of the carious lesion it can be assumed that only some areas maintain activity whereas some are already in an arrested state. (D) The 45° rotated tooth 12 shows no definite ...
context of cam-type impingement, as it serves as the first site of derangement secondary to shear force and compression injury of the hyaline cartilage(26). This may result in chondral delamination leading from the chondrolabral junction and coursing inward(26), the so-called carpet lesion(27)...
on the perirhinal cortex, that spatial memory is more dependent on the parahippocampal cortex, that the subiculum plays an important role in mediating hippocampal–cortical communication, and that the hippocampus is crucial for both semantic memory and episodic memory but that lesion location within ...
The fish specimen had been killed by decapitation and pinned to a dissecting board with the lesion uppermost. The scales around the periphery of the lesion were removed and the underlying skin was seared with a red-hot spatula to sterilize the surface. The fish with the board was then ...
