Quizplus · Accepted Answer

CA left lateral thoracic vertebrae projection showing more than 0.5 inch (1.25 cm) of space between the posterior ribs indicates that the patient's right side was rotated posteriorly, causing an increase in the apparent space between the ribs on the radiograph. To obtain an optimal projection, the vertebral column needs to be positioned parallel with the image receptor (IR), ensuring that the thoracic vertebrae are accurately represented without distortion or unnecessary spacing between the ribs.
