“…It is probably the most widely employed method for diagnosing and monitoring disease activity in patients with TA nowadays (it is certainly the technique of choice in the authors' experience) and it has been extensively used in children ( 96 , 97 ). Diffusion-weighted MRI may be a useful imaging modality to assess the vascular inflammation and discriminate between active and non-active arterial lesions ( 98 ). Drawbacks of MRA include its inability to capture small vessels and the possibility of overestimating the degree of vascular stenosis ( 99 ).…”

Takayasu arteritis is an idiopathic granulomatous vasculitis of the aorta and its main branches and it constitutes one of the more common vasculitides in children. Inflammation and intimal proliferation lead to wall thickening, stenotic or occlusive lesions, and thrombosis, while destruction of the elastica and muscularis layers originates aneurysms and dissection. Carotid artery tenderness, claudication, ocular disturbances, central nervous system abnormalities, and weakening of pulses are the most frequent clinical features. The diagnosis is usually confirmed by the observation of large vessel wall abnormalities: stenosis, aneurysms, occlusion, and evidence of increased collateral circulation in angiography, MRA or CTA imaging. The purpose of this revision is to address the current knowledge on pathogenesis, investigations, classification, outcome measures and management, and to emphasize the need for timely diagnosis, effective therapeutic intervention, and close monitoring of this severe condition.

“…Es probablemente el método más empleado hoy en día para el diagnóstico y seguimiento de la actividad de la enfermedad en pacientes con AT (sin duda es la técnica de elección en la experiencia de los autores) y ha sido ampliamente utilizada en niños (Aluquin, 2002;Andrews, 2004). La resonancia magnética ponderada por difusión puede ser una modalidad de imagen útil para evaluar la inflamación vascular y discriminar entre lesiones arteriales activas y no activas (Kuroiwa, et al, 2017). Los inconvenientes de la ARM incluyen su incapacidad para capturar vasos pequeños y la posibilidad de sobrestimar el grado de estenosis vascular (Sueyoshi, Sakamoto y Uetani, 2006).…”

La arteritis de Takayasu es una vasculitis granulomatosa idiopática de la aorta y sus principales ramas y constituye una de las vasculitis más frecuentes en niños. La inflamación y la proliferación de la íntima conducen al engrosamiento de la pared, lesiones estenóticas u oclusivas y trombosis, mientras que la destrucción de las capas elástica y muscular origina aneurismas y disecciones. Las características clínicas más frecuentes son dolor a la palpación de la arteria carótida, claudicación, alteraciones oculares, anomalías del sistema nervioso central y debilitamiento del pulso. El diagnóstico generalmente se confirma mediante la observación de anomalías en la pared de los vasos grandes: estenosis, aneurismas, oclusión y evidencia de aumento de la circulación colateral en angiografía, MRA o CTA. El propósito de esta revisión es abordar el conocimiento actual sobre patogenia, investigaciones, clasificación

“…However, high cost, radiation exposure, and availability are serious limitations of 18 F-FDG-PET/CT. Magnetic resonance diffusion weighted imaging (DWI) can visualize diffusion capacity of water molecules, and was used to detect the active phase of Takayasu arteritis [3]. Therefore, we applied this technique to visualize aortic inflammatory activity in a patient with IgG4-related disease.…”

Immunoglobulin (IgG) 4-related disease is a systemic inflammatory disease, and it affects vascular system as aortitis, periaortitis, or aneurysm. However, due to a lack of serum biomarker on aortic damage and the multiorgan involvement, it is difficult to assess aortic inflammatory activity of IgG4-related disease. We described a case of IgG4-related pancreatitis and aortitis, which was visualized with magnetic resonance merged image of diffusion weighted and T 1 weighted images. The aortic signal intensity or apparent diffusion coefficient value reduced or increased after oral prednisone administration, respectively. Magnetic resonance diffusion weighted image and apparent diffusion coefficient may be a useful imaging tool for assessment of vascular inflammation in IgG4-related aortitis.
