Ultrasound or MRI: which one checks an implant?
Both scans can look at an implant shell — they differ in cost, access, and what they see best.
When it is time to look at an implant, the two main tools are ultrasound and MRI. US guidance now accepts either one for routine silicone implant surveillance, which leaves many patients wondering which to book.
How the two scans divide the work
Ultrasound is quicker, cheaper, and radiation-free, so it often serves as the first-line check; MRI sees the implant shell in more detail and is commonly used when ultrasound findings are unclear or symptoms persist.
Which scan fits best differs by individual anatomy, implant history, and local availability, so the practical move is to let a specialist match the tool to your situation during a consultation.
