General lumbar AP, lateral projection was until recently preformed to diagnose disease in lumbar spine. However, when unsuspected disease is doubted, both oblique projection is taken naturally to add, sometimes tomography is added. Especially in case of spondylolysis patient, this four of radiology practices application is inescapable, and in such case pars interarticularis is concerned. In oblique or lateral view, pars interarticularis is found along the backbone. It's can be a accomplished. But it's feared that reappearance may go down, because of difference the rotating body. In AP view, pars interarticularis in upper part of lumbar is well expressed but the more it goes down to the low part the reapprarance. In common spondylolysis occur frequently in the L4-5, L5-S area, I performed attesting in order to improve imaging radiograph in making the direction centerray angle cranial 30° after making the patient in the supine position. As the result of it, both pars interarticularis imaging appeared in the more superior reappearance than it appeared in other radiographs. So I am reporting.
