Blood vessel deformities. Magnetic resonance imaging (MRI) scan of the blood vessels of the chest and abdomen in a 23-year-old woman with Takayashu's disease. This is a systemic disease that mainly affects young women, with extensive inflammation of the blood vessels causing a wide range of symptoms and deformities. Here, the lack of flow through the left pulmonary artery (right) is probably due to narrowing of the artery. This is accompanied by a systemic hypervascularisation of the right lung blood vessels (left). The right subclavian artery (upper left) is also narrowed and fainter than the other blood vessels, indicating reduced blood flow. The downward aorta is normal.
