Soft Tissue Neck X-Ray Anatomy

A soft tissue neck x-ray is a vital part of diagnosing various conditions. The different types of soft tissue in the neck include the Retropharyngeal space, Epiglottitis, and Prevertebral soft tissue. This article will cover the basics of neck x-ray anatomy.

lateral soft-tissue neck x-ray

The lateral soft tissue neck x ray is an important diagnostic tool for identifying and treating cervical esophageal reflux disease. It shows a patient’s cervical spine, soft tissue neck, and esophageal lining. This imaging tool has high accuracies and can be used to make a differential diagnosis.

This X-ray is also used in the management of foreign bodies in the upper aero-digestive tract. Usually, patients are referred to an ENT team via their primary care physician. To be eligible for this procedure, the patient must have an upper aero-digestive tract foreign body or a history of it. On admission, the patient is required to undergo a lateral soft tissue neck X-ray to evaluate the foreign body.

Prevertebral soft tissue

The measurement of prevertebral soft tissue thickness (PVST) on cervical X-rays is an important screening tool for spine injury. PVST thickness is a radiographic parameter that can reveal subtle injuries and ligamentous alterations. Traditionally, radiographs were used to determine normal thickness of PVST, but recent advances in CT technology and multidetector computed tomography (MDCT) are making this type of imaging increasingly important for pediatric trauma evaluation.

The prevertebral space is located between the vertebral body and the buccopharyngeal mucosa. This space can appear falsely wide on a soft tissue neck x-ray. It should be no wider than 50% of the associated vertebral body. If the prevertebral space is wider than this limit, it is possible that the patient is suffering from a retropharyngeal abscess. Therefore, x-rays of the soft tissues in the neck must be performed with the neck extended and at end-inspiration to maximize visualization of airways and minimize false widening of the prevertebral space.

Retropharyngeal space

The retropharyngeal space in soft tissue anatomy is a critical area to evaluate for infection. It is the region posterior to the pharynx and anterior to the prevertebral muscles. It is bounded by the carotid sheaths and visceral fascia on the anterior and posterior sides.

This virtual space contains lymph nodes, some fatty tissue, and some vascular structures. It is the primary site of infection for the mouth, and infections can spread through this area. In addition to this space, the neck is bounded by the danger space and the prevertebral fascia.


The appearance of epiglottitis on soft tissue neck X ray anatomy is often a symptom of a more serious condition. Patients with epiglottitis usually have a thickened epiglottis and thickened aryepiglottic folds. This type of epiglottis can be difficult to detect by radiography. For this reason, patients with epiglottitis should receive an examination from a radiologist to determine the cause.

Patients with epiglottitis and healthy controls were included in a case-control study. In each group, the clinical findings were assessed using electronic medical records. Radiographs were reviewed by a board-certified emergency medicine physician and radiologist. Subjective signs were evaluated, as well as the widths of the epiglottis, aryepiglottic fold, and hypopharynx. Using this information, receiver operating characteristic (ROC) curves were created.

Foreign body

Foreign body injuries in the head and neck region are life threatening and difficult to treat. Using various imaging modalities to diagnose these injuries can be helpful in guiding treatment. Each imaging technique has its own advantages and disadvantages. Children are more radiosensitive than adults and should be treated with great caution. The American College of Radiology has guidelines for pediatric head trauma imaging. The PECARN severity scale is often used to determine appropriate imaging procedures.

A three-year-old boy presented to the emergency room with neck pain and blood-stained saliva. He had fallen head-first while playing with his older sister, resulting in a neck injury. The child was conscious but did not have seizures or vomiting. Physical examination revealed no abnormality, but cervical spine radiographs showed a 5.7-cm linear hypodensity extending from the right prevertebral space at C2 to the left C5-C6 space.

Lung window settings

Choosing the right window settings for soft tissue neck x radiography is vital to accurately evaluate neck soft tissue pathology. Using the appropriate window settings can help you identify the presence of abnormal structures, as well as their size and conspicuity. Window settings vary depending on the type of imaging machine and observer preference. Generally, the window level is approximately halfway between the density of the structure and the surrounding tissue. Choosing the wrong window setting can grossly under or over-represent small structures.

The most common lung window settings for soft tissue neck x radiology are erect posteroanterior chest radiographs and lateral chest radiographs. These radiographs are most useful when the patient has reached full lung capacity, when just under half of the lung is free from overlying structures. There are many technical factors that determine how well the lungs are visualized on soft tissue neck x ray anatomy. However, the characteristics of current digital imaging systems enable the clinician to optimize the exposure of the soft tissue neck and lungs.
