Labelling Vertebrae with 2D Reformations of Multidetector CT Images: An Adversarial Approach for Incorporating Prior Knowledge of Spine Anatomy [article]

Anjany Sekuboyina, Markus Rempfler, Alexander Valentinitsch, Bjoern H. Menze, Jan S. Kirschke
2021 arXiv   pre-print
We investigated the superiority of the proposed approach for labelling vertebrae on three datasets: a public benchmarking dataset of 302 CT scans and two in-house datasets with a total of 238 CT scans.  ...  Spinal pathologies can have catastrophic consequences, for example, osteoporotic fractures are associated with an 8-fold higher mortality rate in the longterm [1] .  ...  There also exists a wide variation in the field-of-views (FOV) of these scans, which requires an algorithm for detecting landmarks to be robust to key-point identification.  ...

Axial Spondyloarthritis: Mimics and Pitfalls of Imaging Assessment

António Proença Caetano, Vasco V Mascarenhas, Pedro M Machado
2021 Frontiers in Medicine  
The ability to distinguish between imaging lesions suggestive of axSpA and artifacts or lesions suggestive of other disorders is critical for the accurate diagnosis of axSpA.  ...  Diagnosis may be challenging, particularly in early-stage disease and magnetic resonance imaging (MRI) plays a key role in the detection of subtle or inflammatory changes.  ...  Likewise, vertebral osteoporotic fractures constitute a significant cause of low back pain and disability.  ...
