A Novel cause of abdominal pain presenting with anuria and renal failure.

A girl in early adolescence with autism presented with 3 months of abdominal pain and 36 hours of anuria. She had recently received treatment for urinary tract infections, anxiety and menorrhagia (she had undergone menarche a few months earlier). Due to the pain, she had pulled out an incisor.

Multiparametric 3-D analysis of bone and joint space width at the knee from weight bearing computed tomography.

Objective: Computed tomography (CT) can deliver multiple parameters relevant to osteoarthritis. In this study we demonstrate that a 3-D multiparametric approach at the weight bearing knee with cone beam CT is feasible, can include multiple parameters from across the joint space, and can reveal stronger relationships with disease status in combination.

Design: 33 participants with knee weight bearing CT (WBCT) were analysed with joint space mapping and cortical bone mapping to deliver joint space width (JSW), subchondral bone plate thickness, endocortical thickness, and trabecular attenuation at both sides of the joint.

Quantitative Three-dimensional Assessment of Knee Joint Space Width from Weight-bearing CT.

Background Imaging of structural disease in osteoarthritis has traditionally relied on MRI and radiography. Joint space mapping (JSM) can be used to quantitatively map joint space width (JSW) in three dimensions from CT images. Purpose To demonstrate the reproducibility, repeatability, and feasibility of JSM of the knee using weight-bearing CT images.
