X-ray
Often used for bones, joints, chest problems, fractures, arthritis changes, and quick first-line assessment.

Imaging Test Guide
A patient-friendly guide to X-ray, ultrasound, CT, MRI, bone scan, and other imaging tests—why they are ordered, how to prepare, and what to discuss with the doctor.
See the problem safely
Imaging tests help doctors look inside the body, but the result must be matched with symptoms and examination.
This guide helps patients understand common imaging tests, prepare reports, reduce fear, and ask better questions. It is educational and does not replace clinical judgment.
When imaging should not delay urgent care
Severe chest pain, breathing difficulty, stroke-like weakness, major trauma, loss of consciousness, severe abdominal pain, or rapidly worsening neurological symptoms need urgent medical care. Do not wait for a routine imaging appointment when warning signs are present.
Open Care Decision GuideUltrasound
Uses sound waves and is commonly used for abdomen, soft tissue, blood vessels, pregnancy, and fluid collections.
CT scan
Gives detailed cross-sectional images and is useful for trauma, complex bone injury, chest, abdomen, and urgent conditions.
MRI
Shows soft tissues well, including disc, nerve, ligament, joint cartilage, brain, spine, and marrow-related problems.
Bone scan / nuclear imaging
May help detect bone activity patterns such as stress injury, infection, inflammation, or spread of cancer when clinically needed.
Image-guided procedure
Some tests guide injections, biopsy, drainage, or aspiration. Ask why it is needed, what risks exist, and how to prepare.
Before the scan
A good imaging visit starts with good preparation.
Carry previous reports and images when possible. Tell the imaging center about pregnancy possibility, kidney disease, implanted devices, allergy to contrast, diabetes medicine, or claustrophobia before the scan.
