X-ray, MRI or ultrasound: which joint scans a doctor needs before treatment

In practice, most people need one or two scans, not all three. An X-ray is often the starting point for joint wear, MRI is added when soft tissues or early changes matter, and ultrasound is used to look at tendons and fluid and to guide the needle during the procedure itself.

• What it shows: joint space narrowing, bony spurs, changes in the bone under the cartilage, deformity, old fractures.
• What it misses: early cartilage damage, meniscus and ligament tears, tendons, inflammation in soft tissues.
• Useful detail: for the knee and hip, an X-ray taken while standing shows the real load on the joint and makes narrowing easier to see.

X-rays use a small dose of radiation. If you are or may be pregnant, tell the staff before the scan.

• What it shows: cartilage thinning and defects, meniscus tears, ligament and tendon damage, swelling in the bone marrow, fluid and cysts.
• When it is especially useful: when the X-ray looks almost normal but pain persists, when a meniscus or tendon tear is suspected, or when the doctor needs to plan treatment precisely.
• Before the scan: tell the staff about a pacemaker, metal implants, fragments of metal in the body or pregnancy. The scan is painless but noisy and takes some time, and you need to lie still.

Ultrasound does not see through bone, so it cannot show the deep parts of a joint or the cartilage hidden between bones. That is why it rarely replaces an X-ray or MRI for staging joint wear.

Ultrasound also plays a second role: it guides the needle during an injection. Placing PRP or SVF precisely into the joint under ultrasound control is part of how the procedure is done on our joint treatment page.

This is a general guide. The doctor decides which scans are needed after hearing your symptoms and looking at what you already have.

• The radiologist's written report for each scan. If it is not in English, send it anyway; a translation helps but is not required for a first look.
• The dates of the scans and which side was examined.
• A short description of your symptoms: where it hurts, since when, what makes it worse, previous injuries, injections or operations.

How recent should the scans be? As a rule, images from the last several months are the most useful. If the pain has changed a lot, after a new injury or when the scans are old, the doctor may ask for new ones before making a plan.

The first consultation and the review of your scans are free and can be done online: send your X-rays, MRI or ultrasound with the reports and a short description of your symptoms. If something is missing, the doctor tells you which scan is needed. If PRP or SVF suits your case, the doctor explains the plan and names the cost, which is then fixed in the contract. A personal coordinator stays with you from the first message to the follow-up visits, and scans and questions can be sent by Telegram. Read more on the joint treatment page.
