STIR Magnetic Resonance Imaging: A Noninvasive Method for Detection and Follow-up of Dermatomyositis

Contrast-enhanced Ultrasound in Dermatomyositis- and Polymyositis

“…In accordance with previous observations [15,16,26], we found that patients with acute DM and PM had areas of high muscular signal intensity on T2-weighted images which is considered the most important finding in the different types of autoimmune inflammatory myopathies [6,14]. Although muscle oedema may be an early sign of an inflammatory myopathy, it is non-specific, because it has been described in other pathological conditions or even physical exercise [6,12,13,14,20].…”

Maladies systémiques et vascularites

“…Les séquences axiales en pondération T1 permettent de rechercher une atrophie et une involution graisseuse des masses musculaires, les séquences axiales STIR un oedème musculaire mais également des fascias et de la peau [113,298,354] . Le rehaussement musculaire après injection de gadolinium est superposable aux anomalies de signal observées en STIR et n'est donc pas nécessaire, sauf si l'on souhaite sensibiliser la détection d'une fasciite associée .…”

Magnetic Resonance Imaging of the Idiopathic Inflammatory Myopathies

“…In this study, ankle dorsiflexors were not involved. Muscle edema was seen to be diffuse in every case 25–28 …”

“…Muscle edema was seen to be diffuse in every case. [25][26][27][28] Further studies are needed to determine the sensitivity and specificity of this test, whether it should be part of the routine work-up of myositis, and how the technique performs in relation to standard imaging protocols.…”
