How do lymph nodes look on CT scan?
On CT imaging, normal lymph nodes are well demonstrated on CT. They are ovoid in shape and are of soft tissue density. MR imaging must cover the entire pathway of locoregional spread of the tumour being evaluated and the sequences used depend on the anatomic region assessed.
Can a CT scan detect neck problems?
A CT scan of the cervical spine can help find problems such as infection, tumours, and breaks in the cervical spine. It also can help diagnose narrowing of the spinal canal (spinal stenosis) and a herniated disc in the cervical spine.
Does CT neck show parotid gland?
CT allows more accurate evaluation of tumor location and extent in the parotid gland than any other method and helps distinguish malignant from benign lesions. The normal CT appearances of the parotid region are necessary for precise interpretation of CT images in this region.

It also helps your doctor to evaluate your face, sinuses, and skull or to plan radiation therapy for brain cancer.
How are neck problems diagnosed?

Does a neck CT scan show the head?
A CT (computed tomography) or CAT (computerized axial tomography) head scan looks inside your head and neck. CT and CAT scans are the same test. Special X-ray technology gives your doctor a picture of your skull, brain, eyes, nasal passages, veins, arteries, and tissue.

What can a CT scan of the neck reveal?
CT scans of the neck many times also reveal tumors or infections involving the vocal cords. Neck CT exams are often used to study a lump or mass or to look for enlarged lymph nodes or glands in the neck.
Why would a neck CT scan be performed for angioedema?
The diagnosis of angioedema as the cause of head and neck swelling is usually based on clinical examination findings and the exclusion of other serious diagnoses. Therefore, neck CT may be performed to rule out treatable diagnoses. Neck CT images show focal or diffuse low-attenuation swelling of all or some of the soft tissues of the upper airway.
Which soft tissue structures of the neck should be evaluated?
The soft tissue structures of the neck that are evaluated include nasopharynx, oropharynx, laryngopharynx, thyroid, lateral pharyngeal space, and other soft tissues. The study is best done with intravenous contrast.
What does a CT scan of the submandibular gland show?
Axial contrast-enhanced CT image (a) shows an enlarged hyperenhancing right submandibular gland (black arrowhead) with internal and surrounding edema (black arrow) and overlying thickening of the platysma muscle (white arrow). In comparison, the left submandibular gland (white arrowhead) is normal.
