<unk>  is more commonly discovered by chance rather than intentionally. MRI scans (favored) and X-rays are used to confirm a diagnosis of PAVF when radiological features are present. MRI is used to visualize the extent of the intervertebral ankylosis. Radiographs collected soon after birth are used for diagnosis, as early detection leads to sooner management. Thoracolumbar spine X-rays are often used to confirm a diagnosis, and some prominent features include pinching of the anterior intervertebral disc, with fusion eventually going towards the rest of the vertebrae. Sagittal MRI imaging provides accurate scans of the spine showing non-infectious fusion. CT scans can also be used to locate issues in the vertebrae, but this form of diagnosis currently lacks a significant amount of support from the literature. 3D-CT scans can be utilized to clarify the extent of the vertebral malformations, and assist in the differential diagnosis, as multiple congenital spine defects, such as osteogenesis imperfecta, may accompany<unk> .
