Exploring the use of biphasic quantitative thoracic computed tomography to evaluate halo-pelvic traction in managing severe adolescent idiopathic scoliosis.

Background: Patients diagnosed with severe adolescent idiopathic scoliosis (AIS) often experience reduced pulmonary function and lung volume due to deformities in the spine and ribcage. Presurgical halo-pelvic traction (HPT) has been used to treat severe scoliosis before second-stage surgery. Nevertheless, there is a scarcity of studies utilizing computed tomography (CT) scans to evaluate changes in lung volume post-HPT.

Decreases in lung volume and lung height among ankylosing spondylitis patients with pulmonary function impairment: a 3D CT investigation.

Background: Respiratory compromise among ankylosing spondylitis (AS) patients is characterized by restrictive pulmonary function, leading to the need for a meticulous assessment of lung volume. Compared with conventional pulmonary function tests (PFTs), CT-based lung volume measurements have superior accuracy and are crucial for understanding functional limitations in AS. This study investigated the correlation between CT lung volume and PFT parameters in AS patients, with a focus on changes in CT parameters and lung volume in patients with compromised pulmonary function.
