Emergency Radiology: Case Review SeriesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The newest addition from the popular Case Review Series tackles the burgeoning specialty of emergency radiology. For those readers familiar with the series, the design and layout of this volume hold few surprises. The attractively bound paperback text is divided into three sections, each containing cases with images, diagnoses, and extended commentary. “Opening Round” covers the fundamental cases, while “Fair Game” and “Challenge” present cases in increasing gradations of difficulty. Cases include both traumatic and nontraumatic emergent imaging pathology. (Source: Academic Radiology)

First X-Ray StandardsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
It was 30 years after the discovery of x-rays before world leaders in the fairly new medical specialty decided that something had to be done to define x-ray units and make recommendations for their safe usage. The first significant effort was made at the first International Congress of Radiology in 1925 in London, England. This led at the next international meeting in 1928 to the establishment of two international commissions—one to define radiation units and the other to recommend safe practices.

Peripheral Intravenous Power Injection of Iodinated Contrast Media: The Impact of Temperature on Maximum Injection Pressures at Different Cannula SizesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Heating of CM effectively reduces MIPs using power injection in common IVCs.

Dynamic Evolutionary Changes in Blood Flow Measured by MDCT in a Hepatic VX2 Tumor Implant over an Extended 28-day Growth Period: Time-Density Curve AnalysisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The rabbit VX2 liver tumor is a hypovascular tumor with perilesional enhancement over its lifespan as imaged by MDCT.

The indications and applications for magnetic resonance (MR) imaging (MRI) are continually expanding, and in the era of “image gently” , MR is steadily replacing computed tomography for many diagnostic applications. MRI appears to be the imaging modality of choice for the future, and a thorough understanding of MR equipment, physics, pulse sequences, contrast agents, and image interpretation is essential for radiology residents, fellows, and practicing radiologists.

Flat Panel Volume Computed Tomography of the Coronary ArteriesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Postmortem coronary fpVCT provides an accurate and reproducible method for the quantitative assessment of both luminal stenosis and atherosclerotic plaque size. Because of its high spatial resolution, the method should be sufficiently accurate to reliably detect the lipid pools of vulnerable plaques. (Source: Academic Radiology)

The Value of Diffusion-Weighted Imaging in Characterizing Focal Liver MassesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: Solid liver lesions have a lower ADC than cysts and hemangiomas. However, there is no significant difference in ADC between solid benign and malignant lesions. DWI appears to have only minimal additional value over currently used MRI sequences in characterizing liver masses. (Source: Academic Radiology)
