Cervical spine x ray positioning3/31/2024 ![]() ![]() The shoulder adjacent to the grid rests firmly against it. The vertebral column is centered to the midline of the grid. The body is rotated 20 degrees posterior or anterior (AP or PA oblique, respectively). Position of patient Standing or sitting erect in a lateral position in front of a vertical grid. Purpose and Structures Shown An oblique projection of the thoracic spine to demonstrate the zygapophyseal articulations. Video Credit : RadPositioning Thoracic Spine AP or PA Oblique Projection Upright The patient may breathe normally when the exposure is being taken. The long axis of the spine is horizontal. Position of part The patient is positioned with knees bent to stabilize the body. The left lateral position is preferred because placing the heart closer to the IR minimizes overlap. ![]() Position of patient Lying on the left or right side (lateral recumbent position). Purpose and Structures Shown A basic view of the thoracic spine. Ribs, shoulders, diaphragm, and lungs are visible. The vertebral column is aligned to the middle of the image. The patient is asked to stop breathing when the exposure is taken. Position of part The gonads are shielded. The head should rest directly on the table or on a thin support to avoid exaggerating the thoracic kyphosis. The arms are placed by the side of the body and the shoulders are flat on the table. Two radiographs may be necessary for the upper and lower thoracic regions. Purpose and Structures Shown A basic view of the thoracic spine showing all 12 thoracic vertebral bodies, intervertebral disc spaces, transverse processes, and costovertebral joints. The lateral projection shows the left and right hemidiaphragm, vertebral bodies, intervertebral disc spaces, and posterior ribs. In addition to the thoracic vertebral bodies, spinous processes, and transverse processes, a good quality thoracic spine AP projection shows the left ventricle, gastric bubble, right/left hemidiaphragm, posterior ribs, and right/left clavicle. Thoracic Spine AP or PA Oblique Projection Recumbent.Thoracic Spine AP or PA Oblique Projection Upright.In this preliminary study, the application of erect WB radiography technique in evaluating the lower cervical region of adult non-trauma patients gives limited advantage.This article discusses radiographic positioning of the thoracic spine for the Radiologic Technologist (X-Ray Tech). Regardless of the imaging system or techniques used, adequate instructions given to the patient before and during the imaging procedure of C-spine lateral radiography demonstrated a significant improvement in visualizing the lower C-spine region. ![]() The instruction given to the patient significantly correlated with the visibility of the lower C-spine region within each group of WB and NWB in both imaging systems.Ĭonclusions: The visibility of the number of vertebral bodies in the lower C-spine region in either CR or DR systems did not demonstrate any enhancement with the WB technique. However, a significant difference was identified for CR (p = 0.012). Further, no significant relationship (p > 0.05) was observed between the WB technique and the visualization of C7-T1 junction in DR systems. Results: There was no significant difference (p > 0.05) in the visualization of the number of vertebral bodies between the two techniques of WB and NWB for CR or DR. The instructions given by the radiographer to the patient for the imaging procedure were also assessed on the Likert scale (very good, good, fair, poor, very poor). Methods: Forty-four CR (29 WB and 15 non-WB – NWB) and 61 DR (26 WB and 35 NWB) lateral C-spine radiographs were prospectively evaluated to assess the visible number of cervical vertebral bodies and C7-T1 junction. The study was conducted using both computed radiography (CR) and digital radiography (DR) systems. This study was conducted to determine the effect of the weight-bearing (WB) technique in visualizing lower cervical vertebrae and cervicothoracic junction (C7-T1) on standing lateral cervical radiographs of adult non-trauma patients. However, the effectiveness of these techniques still remains unclear. Introduction: Various positioning techniques are utilized to enhance the visualization of lower cervical vertebrae on lateral radiographs.
