Your Guide to Diagnostic Imaging: X-ray, Ultrasound, CT & Mammogram

Your Guide to Diagnostic Imaging: X-ray, Ultrasound, CT & Mammogram

If your doctor has sent you for a scan, the different names can be confusing. Here's a simple guide to the main types of diagnostic imaging we offer at Hargreaves Hospital in Mandeville — all under one roof.

X-ray

Quick and reliable, an X-ray is ideal for looking at bones and the chest, and for spotting fractures. It takes just minutes.

Ultrasound

An ultrasound uses sound waves — no radiation — to view soft tissues in real time, which is why it's used in pregnancy and for the abdomen, pelvis and blood vessels.

CT scan

A CT scan combines many X-ray views into detailed cross-sectional images, valuable for trauma, tumours and vascular conditions.

Mammogram

A mammogram is a specialised breast X-ray used for screening and diagnosis. Early detection saves lives, so don't put it off.

Which do you need?

Your doctor decides based on your symptoms — and often you'll only need one. If you have a referral and aren't sure how to prepare, call us. See all options on our radiology page.
