Spine Quantitative Computed Tomography (QCT) (Spine QCT)

September 29, 2017 updated by: Children's Hospital of Philadelphia

Spine Quantitative Computed Tomography (QCT) for the Assessment of Osteoporosis on Children

The purpose of this study is to compare healthy children to children who have a chronic illness called Juvenile Idiopathic Arthritis (JIA). JIA is a childhood disease that causes swollen joints that are often stiff and painful. JIA affects about 1 in 1,000 children age 16 and younger.

Study Overview

Status

Completed

Conditions

Detailed Description

Children with chronic illnesses are at risk for bone fragility due to inflammation, glucocorticoid therapy, physical activity limitation, malnutrition, and pubertal delay. The impact of low bone mass during childhood may be immediate, resulting in childhood fractures, or delayed, due to suboptimal peak bone mass attainment.
