Ultrasound appearance of regenerative peripheral nerve interface with clinical correlation
ConclusionUltrasound imaging can demonstrate various morphologic changes involving the nerve, muscle, and interface between these two biological components of RPNIs. These changes correspond to expected degenerative and regenerative processes following nerve resection and muscle reinnervation and should not be misconstrued as pathologic in all cases. N5 and N1 morphologic type changes of the RPNI were found to be associated with symptoms. (Source: Skeletal Radiology)

Weight-bearing cone-beam CT: the need for standardised acquisition protocols and measurements to fulfill high expectations —a review of the literature
AbstractWeight bearing CT (WBCT) of the lower extremity is gaining momentum in evaluation of the foot/ankle and knee. A growing number of international studies use WBCT, which is promising for improving our understanding of anatomy and biomechanics during natural loading of the lower extremity. However, we belie ve there is risk of excessive enthusiasm for WBCT leading to premature application of the technique, before sufficiently robust protocols are in place e.g. standardised limb positioning and imaging planes, choice of anatomical landmarks and image slices used for individual measurements. Lack of stan dardisation c...

Morphologic, dynamic and high-resolution microscopy MRI in early-onset spondyloarthritis finger dactylitis
ConclusionsOur MRI study on early-onset dactylitis demonstrates that flexor tenosynovitis, joint synovitis and oedema of the digit soft tissue are the predominant alterations visible in the early phase of evolution of dactylitis and that, therefore, enthesitis may not be considered the primary lesion of dactylitis.

Radiomics-based approaches outperform visual analysis for differentiating lipoma from atypical lipomatous tumors: a review
ConclusionRadiomic models may show improved performance for differentiating ALTs/WDLs from benign lipomas compared to conventional analysis. However, considerable variability between radiomic approaches exists and future studies evaluating a standardized radiomic model with a multi-institutional study design and preferably fully automated segmentation software are needed before clinical application can be more broadly considered.

Radiologists should use the hip-knee-ankle angle rather than the mechanical axis deviation to describe knee alignment
ConclusionHKAA should be used instead of the MAD because it is more clinically relevant and takes the same amount of time to be measured. (Source: Skeletal Radiology)
