Volumes obtained from reconstructions in either plane were essentially identical. There was a linear increase in log-transformed pituitary volume with age, but relatively weak correlations with height or body mass index. There was no gender difference and only weak correlations between pituitary height and pituitary volume and between estimated pituitary volume calculation and measured pituitary volume. We provide age-related reference ranges for pituitary volumes in graphical and tabular forms.

Background-Totally implantable vascular access devices (TIVADs) are accepted as a safe and eVective method of facilitating long term intravenous therapy. We report our experience of the use of these devices in children with cystic fibrosis with a particular focus on the incidence and type of complications. (Thorax 1998;53:285-289)

ABSTRACT

No abstract

We report a case of a bleeding Meckel's diverticulum where scintigraphic and sonographic findings were thought to suggest an ileal duplication. We are not aware of previous reports of sonographic imaging of an uncomplicated Meckel's diverticulum.
