Eric M. Wilner: Are We Really Practicing Medicine Today?
While the reasons for ordering such imaging studies are many (ranging from medicolegal concerns to patients and their families surfing the Internet and insisting on particular studies), we need to stop what we are doing, call a time-out, and talk and listen to each other.

James H. Thrall: Commentary on "Are We Really Practicing Medicine Today?"
Radiology has led the transformation of medicine into the digital and molecular age, and no specialty has made more technologic progress; now, let us make sure that we lead the rest of medicine in not changing something even more important—what it means to be a doctor, to be a medical professional.

Brian C. Bowen and Charles L. Truwit: MR Angiography versus CT Angiography in the Evaluation of Neurovascular Disease
Unlike CT angiography and contrast-enhanced MR angiography, time-of-flight MR angiography requires no carefully timed contrast agent injection and is repeatable.

Charles L. Truwit and Brian C. Bowen: CT Angiography versus MR Angiography in the Evaluation of Acute Neurovascular Disease
Although MR angiography offers many valuable advantages, they are, in my opinion, more related to the screening population and to the nonemergent evaluation of neurovascular disease.

Sixty-four–section coronary CT angiography can depict in-stent low-attenuation filling defects with a higher degree of accuracy (91%) and negative predictive value (98.5%; 95% confidence interval: 90.9%, 99.9%), which suggests an important role of noninvasive coronary CT angiography for ruling out significant stent restenosis in patients with otherwise equivocal test findings.

On the basis of only the numbers of the choline-plus-creatine–to-citrate ratio, which originated from 1.0-cm³ voxels and was measured in less than 10 minutes, three-dimensional proton MR spectroscopy at 3 T with only external array coils had a high specificity for the discrimination of cancer from healthy tissues; therefore, this technique shows potential for the metabolic identification of prostate cancer.
