MR shank

MRI of the lower leg is a completely safe, non-invasive and painless examination. It allows accurate imaging of both soft tissues and bony structures of the body.

Our laboratory has one of the most modern MRI machines in Poznan and Poland, namely Siemens Magnetom Sola 1.5T. Images made with this apparatus are characterized by extraordinary quality, unprecedented among older generation cameras. On top of that, the inside of the MRI is 10 cm larger in diameter, providing comfort to claustrophobic patients without compromising the quality of the examination, which happens in so-called open MRIs.

Bone anatomy of the lower leg

The shank, also known as the shin, consists of two long bones:

  • sagittal
  • tibia

The tibia is much thicker and more massive than the fibula, as the entire weight of the body is supported on it. The fibula, on the other hand, is quite thin, lateral to the tibia. The two bones together form the bony skeleton of the shin. They are connectedfromtop by the tibiofibular joint, whichnotconnects tothe knee joint, however. Between the bones is the interosseous membrane of the shin, made of tough connective tissue. It connects the two bones to each other along their entire length.

The shin provides support for the entire body, enables walking, and is the attachment of many muscles. It co-forms the upper ankle joint that allows the foot to move.

Contraindications for magnetic resonance imaging of the lower leg

Absolute contraindications to MRI include any electronic devices implanted in the patient’s body, such as:

  • pacemakers, defibrillators or cardiac pacemakers
  • insulin pumps
  • neurostimulators
  • Hearing prostheses, intracochlear implants
  • Any ferromagnetic prosthesis (old type), metal bullets after being shot, metal filings (especially in the eye) and other metals placed in the body.
  • Dental implants, retainers or even fixed braces are not a contraindication to the test.
  • Currently, a large number of implants are not a contraindication to examination in the high electromagnetic field found in MRI, because they are created from alloys of materials that do not show ferromagnetic properties, such as titanium.
  • A special contraindication is the patient’s pregnancy, especially the first trimester! Patients during pregnancy are strongly discouraged from having an MRI unless the mother’s life is at risk and the test cannot be postponed.

Course of MR examination of the lower leg

On the day of the examination, you must appear half an hour before your appointment to complete the questionnaire. We ask that each patient bring all medical records pertaining to the area being examined, i.e. previous descriptions and records of imaging studies, hospital discharges, appointment cards, etc.

The MRI examination of the lower leg lasts from 45 minutes to one hour (in the case of examinations with contrast). During the examination, you should lie as still as possible, in particular, you cannot move the examined lower leg.

The MRI makes loud noises during the test, but the patient is always given earplugs or headphones to muffle the noise.
