Significance of X-rays in Diagnosis
Jan 18, 2025
X-ray is a grey-scale picture of the area to be studied. It is quick, painless, and is used to screen bones and lungs, among other indications. X-ray beams pass through the body and give an image based on differences in the density of various organs of the body. A single or few X-rays do not cause significant radiation. Weighing with the information they give to guide treatment, X-rays are one of the safest techniques available.
Why is an X-ray done?
X-rays are recommended to look at
· Sinuses
· The lungs
· Bones/fractures
· Foreign body ingestion (if
radio-opaque)
· Bowel gas pattern
· Bone age/bone growth
· The correct placements of the
feeding tube, endotracheal tube, central line, and umbilical vein/artery
catheters
· Teeth and the tissues around
them and the Position of DJ stents/implants
How to prepare for an X-ray?
· No specific preparation is
needed unless the doctor specifies
· Few X-rays may require bowel
preparation
· You need to remove jewelry, and
hair pins, or reposition some clothing that may obscure the image due to
unwanted shadows
· Keep a record of previous
X-rays so that appropriate comparisons can be made by your doctor
Safety precautions for kids during
X-rays:
· Explain to the children and
prepare them mentally before the procedure

the X-ray pictures are taken
· You can check with the doctor
if some other imaging techniques like MRI or ultrasound can be used
