![]() A message is sent to both the PACS/viewer and the reporting solution from the model with this information. If you are struggling to see down to the level of C7/T1, a fourth swimmer’s view can be requested. The model identifies the presence of a cervical rib or cervical ribs. Typically there are three standard views provided when a cervical spine X-ray is performed, these include a lateral, antero-posterior (AP) and odontoid/open-mouth view. Images obtained from the radiograph sent to the PACS/viewer and the AI model. Radiologists can easily miss a cervical rib (or ribs, if bilateral) and would benefit from an algorithm that can detect and alert the radiologists as this congenital variant has been known to cause TOS. The patient is found to have a right-sided cervical rib, causing TOS. An x-ray of the cervical spine is performed. Ī 30-year-old female presents with numbness and tingling of her right upper extremity. In patients with forward head position, cervical spine can be considered similar to a protracted position in which the lower cervical vertebrae are flexed in a forward glide with the upper cervical vertebrae extended 1,2,27. The PA oblique cervical spine projections are supplementary views to the standard AP, odontoid and lateral images in the cervical spine series and are always done bilaterally for comparison purposes. While individuals with a cervical rib are ten times more likely to develop TOS, this variant is commonly overlooked in medical imaging. Minimum SID of 60 inches-72 inches (150-180 cm) Positioning for a lateral projection of the cervical spine For non-trauma cases, position the patient in a lateral position, either seated or standing, with the patient's shoulder against a vertical cassette holder. Citation, DOI, disclosures and article data. However, in some cases (up to 10% of the affected individuals), cervical ribs can cause problems, such as thoracic outlet syndrome (TOS) or brachial plexopathy by compressing the brachial plexus or the subclavian vessels. Occurring in less than 1% of the population, a cervical rib can vary in size and shape and is often an incidental finding without symptoms. Cervical rib, which is a congenital anomaly, is an accessory rib that grows above the first rib from C7 and can be on the right, left, or both sides. ![]()
