Quantity quotient reporting. Comparison of various models.

Quantity quotient (QQ) reporting has been proposed by several authors to improve or support the present situation of presenting quantitative laboratory results. This proposal is based on a concept (symmetrical model) known from the intelligence quotient, which was developed to make intelligence tests comparable. In laboratory medicine, however, most measurands follow a non-symmetrical (skewed) distribution, leading to a compression of the QQ values at the lower end of the reference interval.

The future of imaging techniques for cancer patients in The Netherlands : A Delphi study.

There is a need in The Netherlands to understand the future prospects of imaging techniques in cancer care to deal with current and expected capacity decisions. For this, a Delphi research was performed with a panel of 35 noted experts. The panel anticipates that the application of imaging techniques (e.
