Soft tissue neck radiographs are commonly requested in ED either to look of foreign bodies (e.g. fish bone) or, particularly in kids, to assess retropharyngeal abscesses or upper airways infections (e.g. croup and epiglottitis).
What is X-ray mAs?
Milliampere-seconds, also more commonly known as mAs, is a measure of radiation produced (milliamperage) over a set amount of time (seconds) via an x-ray tube. It directly influences the radiographic density, when all other factors are constant.
Can a neck X-ray show a tumor?
X-rays of the spine, neck, or back may be performed to diagnose the cause of back or neck pain, fractures or broken bones, arthritis, spondylolisthesis (the dislocation or slipping of 1 vertebrae over the 1 below it), degeneration of the disks, tumors, abnormalities in the curvature of the spine like kyphosis or …

How does kVp and mAs affect image quality?
The first experiment showed that, when the film density is kept constant, the higher the kVp, the lower the resolution and image contrast percentage; also, the higher the mAs, the higher the resolution and image contrast percentage.
What does kVp and mAs mean?
* kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts.
Does head CT scan show neck?
A CT (computed tomography) or CAT (computerized axial tomography) head scan looks inside your head and neck.
Why is there a little lump on my neck?
The most common lumps or swellings are enlarged lymph nodes. These can be caused by bacterial or viral infections, cancer (malignancy), or other rare causes. Swollen salivary glands under the jaw may be caused by infection or cancer. Lumps in the muscles of the neck are caused by injury or torticollis.
How long does soft tissue in neck take to heal?
How long will it take to recover from a soft tissue injury? The recovery time from grade 1 soft tissue injuries in one to two weeks and three to four weeks for a grade 2. Grade three soft tissue injuries require immediate assessment and treatment, with much longer recovery times.
