![]() ![]() If an oblique cervical spine image has a left side marker, the left intervertebral foramina are demonstrated (see left) This convention is a simple aid to the radiologist. The cervical spine images on this page all have the side marker on the side of the intervertebral foramen demonstrated. Some centres will prefer the side marker to also refer to the intervertebral foramina demonstrated. ![]() The images need to be flipped horizontally to be viewed in the anatomical position. The PA obliques have the marker placed PA on the IR on the side touching the IR. Given that they are taken AP, they do not need to be flipped horizontally to be viewed The AP obliques have marker placement on the side away from the IR. Oblique cervical spine views can be performed erect or supine and AP or PA.Įssentials of Skeletal RadiologyTerry Yochum and Lindsay Rowe3rd Edition, Volume 1 Osteophyte impingement of intervertebral foramen arrowed Patient with severe degenerative disease. The cervical nerve roots can be seen in this model exiting through the intervertebral foramina Oblique radiographs of the cervical spine are necessary if the condition is to be confirmed radiologically. This is a common cause of brachialgia in middle age. The presence of osteo-arthritis in the unco-vertebral articulations of the lower cervical spine frequently produces pressure on the nerve-roots lying in the intervertebral foramina. The oblique view shows the intervertebral foramina formed by the inferior notch of the pedicle of the vertebrae above and the superior notch of the pedicle of the vertebrae below. This can be caused by pressure on the nerves which exit the cervical spine through the intervertebral foramina. The oblique view of the cervical spine can be important in patients with pain and/or altered sensation in their upper limbs. This page is dedicated to answering some of these questions What exposure technique should be employed?.Oblique views in radiography tend to be problematic. ![]()
