Correlation between ultrasound features of refractory secondary hyperparathyroidism and lab indexes / 中国医学影像技术

ABSTRACT

Objective To analyze correlation between ultrasound features and clinical lab indexes of refractory secondary hyperparathyroidism (SHPT).Methods Two-dimensional ultrasound and CEUS were performed in 30 patients with refractory SHPT before operation.The sum volume of hyperplastic parathyroid glands and sum volume of enhanced area of parathyroid glands in each patient were measured and calculated.Clinical lab indexes,including serum intact parathyroid hormone (iPTH),serum calcium,serum phosphorus,serum alkaline phosphatase (ALP) were recorded,and corrected serum calcium and corrected serum calcium-phosphorus product were calculated 2 days before operation.The correlation between sum volume of parathyroid glands and lab indexes was analyzed.Results There were positive correlations (r=0.48,0.50,both P=0.01) between sum volume of parathyroid glands,sum volume of enhanced area of parathyroid glands and iPTH level.No correlation was found between the volume of hyperplastic parathyroid glands and serum calcium,serum phosphorus,ALP,corrected serum calcium,nor calcium-phosphorus product (all P＞0.05).Conclusion The sum volume of parathyroid can reflect active state of parathyroid glands,which is helpful to diagnosis and monitoring refractory SHPT.
