CT Scan
A CT scan uses X-rays and computer processing to create detailed cross-sectional images of the body.
When to get help quickly: CT is often urgent in trauma, stroke symptoms, sudden severe headache, chest pain, severe abdominal pain, breathing difficulty, or suspected internal bleeding.
Common symptoms
A CT scan is ordered because of symptoms or findings such as severe pain, injury, breathlessness, fever, swelling, a suspected stroke, or a concern that needs a fast and detailed look inside the body.
When imaging helps
CT helps when doctors need rapid detail in emergencies, want to look for internal injury, infection, cancer, bleeding, blockage, or complications that may not show clearly on a regular X-ray.
What radiology does
It is often used in emergencies, cancer assessment, trauma, infection, abdominal pain, and many other conditions because it is fast and detailed.
What usually happens next
The scan itself does not treat disease, but its findings often shape urgent decisions, follow-up testing, or treatment planning.
