[The progress of ultrasonography imaging about secondary hyperparathyroidism].

Percutaneous ethanol injection therapy (PEIT) is a useful therapy of secondary hyperparathyroidism due to chronic renal failure. We need information as well as possible about vascular image of swelling parathyroid glands and detail of structure for performing safely and effectively. This paper discusses about ultrasonography up to date for parathyroid gland including Fusion 3D and Contrast Fusion 3D imaging.
