Some Notes on Critical Appraisal of Prevalence Studies; Comment on: “The Development of a Critical Appraisal Tool for Use in Systematic Reviews Addressing Questions of Prevalence”

Decisions in healthcare should be based on information obtained according to the principles of Evidence-Based Medicine (EBM). An increasing number of systematic reviews are published which summarize the results of prevalence studies. Interpretation of the results of these reviews should be accompanied by an appraisal of the methodological quality of the included data and studies. The critical a...

MRI thermometry based on encapsulated hyperpolarized xenon.

A new approach to MRI thermometry using encapsulated hyperpolarized xenon is demonstrated. The method is based on the temperature dependent chemical shift of hyperpolarized xenon in a cryptophane-A cage. This shift is linear with a slope of 0.29 ppm °C(-1) which is perceptibly higher than the shift of the proton resonance frequency of water (ca. 0.01 ppm °C(-1)) that is currently used for MRI t...

Volumetric thermometry

Background/introduction Many applications of thermal therapy would benefit from temperature distribution measurements with high spatial and temporal resolution that cover a large 3D volume. Although MRI can acquire 3D temperature measurements, it is not possible to obtain fully sampled 3D MRI measurements that cover the insonified field of view with sufficient spatial and temporal resolution fo...

Nuclear Thermometry

The concept of a nuclear temperature was introduced some seventy years ago in pioneering works performed by Bethe [1] and Weisskopf [2]. The goal was to describe the formation and the decay of a compound nucleus in reactions induced by light projectiles, mostly neutrons. Later on, the concept of a nuclear temperature was extended to reactions involving highenergy projectiles and heavy ions [3]....
