Digital Radiography (X-ray)
X-rays provide fast, low-cost imaging for bones, lungs, and lines/tubes placement.
What is X-ray?
X-ray uses a small dose of ionizing radiation to create a 2D projection image. It is the first-line test for fractures, chest evaluation, and device positioning.
How it works: An X-ray tube sends photons through the body to a detector. Dense structures like bone block more rays and appear white, while air-filled areas appear dark.
Common Uses of X-ray
Fracture detection
Identify breaks, dislocations, and alignment.
Chest evaluation
Assess pneumonia, effusion, lines, and tubes.
Abdominal overview
Screen for obstruction, free air, stones.
Advantages
- ✓Fast and widely available
- ✓Low cost
- ✓Good for bones and hardware checks
Limitations
- ⚠Uses ionizing radiation
- ⚠Limited soft-tissue detail
- ⚠2D projection can hide overlapping pathology
Preparation & What to Expect
Before the Exam
Remove metallic objects and jewelry; inform if pregnant.
During the Exam
Stay still and follow breath-hold instructions for chest films.
After the Exam
Resume normal activity immediately.
Related Imaging Methods
Use CT for cross-sectional detail or MRI for soft tissue.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
