SCIENCE TO PRACTICE:

Deborah Levine: Science to Practice: Can MR Oxygenation Imaging Be Used to Assess At-Risk Pregnancies?
By combining emerging technologies and in response to the need for noninvasive measurement of fetal and placental oxygenation, Wedegärtner et al demonstrate that 3-T BOLD MR imaging can be used to depict changes in fetal sheep organ oxygenation induced by maternal hypoxia.

Review:

Gregory T. Sica: Bias in Research Studies
Bias is a ubiquitous and insidious problem in research study design and execution, and while no study design is exempt from bias, some are more prone to particular types.

How I Do It:

Lane F. Donnelly and Janet L. Strife: Establishing a Program to Promote Professionalism and Effective Communication in Radiology
Although it is difficult to measure the subjective attributes that constitute excellent professionalism and communication skills and thus result in an outstanding radiologist, in our opinion, those departments that develop programs that stress the importance of these skills and create measures that motivate positive department behavior will be the most successful.

The accuracy values achieved for classification of stenosis with findings at MR angiography compared with those for classification with findings at digital subtraction angiography were fairly low in our study, with a value of 56.4% for the gadodiamide group and 52.8% for the gadopentetate group, because a single dose of 0.1 mmol/kg was too low to obtain sufficient contrast enhancement of smaller abdominal and iliac arteries.
