[MRI in diagnosis and follow-up of patients with adult metabolic disease: contribution of new techniques]. / Place de l'IRM dans l'orientation diagnostique et le suivi des maladies métaboliques: intérêt des nouvelles techniques.

INTRODUCTION: Conventional MRI allows diagnostic and prognosis approaches for patients with suspected metabolic disease. BACKGROUND: Bilateral and symmetrical abnormalities are the most suggestive aspects. Signal characteristics (intensity, difference of signal on various sequences), lesion extension and location provide important etiological information. Non-conventional MRI techniques are particularly interesting for pathophysiology. Different MRI modalities offer promising techniques for monitoring treatments and patient follow-up. CONCLUSION: Combining different MRI modalities can contribute to the diagnosis and help improve understanding of the pathogenic mechanisms of adult metabolic diseases; they offer promising options for the prognosis and treatment follow-up.
