Magnetic Resonance Imaging MRI

Magnetic resonance imaging is dependent on the alignment of hydrogen nuclei (protons) in water in a magnetic field. The MR signals that provide the diagnostic information are produced within the patient's tissue in response to radiofrequency pulses, generated by a transmitter coil built into the construction of the magnet. Between the electromagnetic radiofrequen-5 cy pulses, the nuclei relax and realign releasing energy which is recorded and used for imaging of the tissue. This imaging technique provides good spatial resolution as well as a good ability to distinguish between tissues, and is being extensively used in other areas of medicine.

In HS, MRI has shown lesions with increased skin thickness, induration of subcutaneous tissues and abscess-like lesions [3]. The skin changes are not reported as distinguishable from other those of other disorders, e.g. erysipelas or cellulitis. It may however be useful in the identification of fistulas and deeper sinus tracts and abscesses [4]. Similarly, MRI may give information about the presence of alternative causes of fistulation to the skin, for example, and as such help to identify patients who need different treatment.

Currently there are no commercially available coils specifically for skin imaging, and although these are being developed experimentally, this method appears most helpful when studying deeper or extensive involvement.
