Magnetic resonance imaging: the basic physical and clinical concepts. Part II.

Noninvasive evaluation of the human body has become an essential tool in the diagnosis of disease processes. Recent developments in nuclear magnetic resonance imaging (MRI) have extended a powerful chemical analytic technique to the medical imaging field. This article presents the fundamental principles of MRI in terms of the concept of transmission and reception of energy. The physical principles of spin resonance were discussed in Part I. Spin relaxation and pulse sequences will be examined in Part II and III. A selected bibliography directs the reader to a more detailed discussion of the pertinent physics.

The accuracy of tympanic temperature measurement in children.

PURPOSE: To evaluate the accuracy and consistency of tympanic temperature measurement in children. METHODOLOGY: A correlational study compared tympanic temperature measurements with oral, axillary, and rectal measurements. A convenience sample of 209 hospitalized children ages newborn to 12 years was stratified according to age. Cross tabulation by fever was analyzed for sensitivity and specificity. RESULTS: Tympanic measurements were significantly correlated to oral, axillary, and rectal measurements. The correlation between axillary and tympanic in newborns was lowest. Tympanic measures identified fevers more often than oral or axillary measurements when compared to rectal measurements. CONCLUSIONS: Tympanic measurement in newborns was not sufficiently accurate. Tympanic measurements may be used routinely in children older than 3 years.

Look to the future.

With the UKCC and the national boards up for review, a consultation document proposes a radical overhaul of these governing bodies. Professional organisations have until the end of next month to respond. Here, their leaders give Nursing Times a hint of what they may say.

Dignified dying as a nursing outcome.

The goal for humanistic end-of-life care is to maintain quality of life and personal dignity. The nursing outcome called "dignified dying" is defined as maintaining personal control and comfort with the approaching end of life and lists indicators for measuring this. These criteria enable nurses to measure the effectiveness of their nursing interventions, monitor patient progress over time, and summarize research data. This article describes the development of this outcome and illustrates its use with a case study.
