A little clarity before you call

Find the right questions.
Then ask the imaging team.

MRI — magnetic resonance imaging — uses a magnetic field to create images inside the body. The scanner’s design is one part of choosing an exam.

Understand the designs

Bore: a tunnel-shaped scanner. Wide-bore describes a wider tunnel; short-bore describes a shorter tunnel. Neither label alone tells you the usable space.

Open on sides: a scanner with open sides. Space between the upper and lower parts is not a circular opening diameter. An unknown opening does not mean unlimited space.

Upright: a design that may allow some exams in a seated or standing position. Confirm available positions and exam suitability with the provider.

Read measurements together

Opening is the published circular diameter in centimeters (cm). Padding and coils reduce the space available for your body. Body shape, positioning and the part being scanned also matter.

Table limit is the provider’s published weight limit in pounds (lb). It is an equipment specification, not confirmation that a person can safely have an exam on that scanner.

Field strength is reported in tesla (T). A larger number does not automatically mean the right scanner for your exam. Your clinical team determines the protocol and equipment needed.

Before you book, ask

  1. Which exact scanner will be used for my exam, and are these published specifications still current?
  2. What usable space remains after positioning, padding and coils? Can the team assess fit beforehand?
  3. Is this design appropriate for the body part and imaging protocol my clinician requested?
  4. What MRI safety screening, referral and preparation do I need?
  5. What are the current appointment options, charges and insurance arrangements?

Site maximums describe the highest listed specifications at a location. They do not apply to every scanner or every appointment.
