Magnetic resonance imaging in primary amyloidosis. 1987

L Benson, and A Hemmingsson, and A Ericsson, and B Jung, and G Sperber, and K A Thuomas, and P Westermark

Twelve patients with primary amyloidosis (AL) were investigated with magnetic resonance imaging (MRI). In 9 patients an abnormal thickening of the heart walls was present and in 2 macroglossia was found at MRI. T1 was significantly increased in liver (p less than 0.05) and subcutaneous fat (p less than 0.01) while it was decreased in the spleen (p less than 0.05). T2 was significantly decreased (p less than 0.01) in the spleen in patients with amyloidosis, while it was not significantly altered in the liver or subcutaneous fat. After therapy T1 of the liver was reduced towards normal values in 4 patients. It is concluded that MRI might be a method to quantitate the amount of amyloid deposits in the tissue, and that the effect of therapy may be monitored with this technique.

D000686 Amyloidosis A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits. Amyloidoses
