How To Read a Chest X-Ray (CXR)

allen — Thu, 08 Jan 2009 01:14:24 GMT

Every physician has their own method of evaluating films. Most will tell you that it doesn't so much matter what method you chose, but rather that you approach an image systematically, the same way every time, in order to ensure the fewest possible omissions and errors. I have found the following method effective, feel free to adapt and post comments.

Mickey Mouse Sign

allen — Thu, 08 Jan 2009 01:14:24 GMT

A 7 year old girl presented to ED after swallowing a foreign body. Initial CXR shows a foreign body at the level of T8. There was no change in the position of the Mickey Mouse key ring after 8 hours. No pneumomediastinum or pneumothorax. The airway is patent. It was finally retrieved with oesophagoscopy. Foreign body ingestion in children is a common ED presentation. If not removed, metallic/caustic material (eg, battery) can erode into oesophagus, causing ulceration or even perforation. If passed into stomach, most round FBs cause little problem. The most common locations for FBs to lodge in the oesophagus are: (a) cricopharyngeal muscle, (b) aortic knob or (c) gastroesophageal junction. Follow up examinations to look for passage of FBs are essential, especially if they are pointed, long, irregular or jagged.

MRI for the detection of early breast cancer

allen — Thu, 08 Jan 2009 01:14:24 GMT

After a lot of the not-so-Respectful Insolence™ of the last couple of weeks, I've been meaning to get back to living up to the name of the overall mega-blog, namely ScienceBlogs. Meeting up with my fellow SB'ers over the weekend in New York Fortunately, last week a topic just so happened to pop up related to my area of expertise, when a study in The Lancet was published evaluating the use of MRI in breast cancer. It happened to get a bit of press when it came out last month, some of it a bit breathless, as though this were a revolutionary observation. (To some extent it was unexpected, but it wasn't really revolutionary.) I'm also waiting with a little bit of trepidation for my patients to start asking about it or to start demanding MRI once again, as I did a few months ago when some rather poorly justified guidelines were published by the American College of Physicians. Don't worry, though. I'm sure I'll find some red meat topics again soon enough.

Siemens Syngo Colonography PEV For CT Colonography Examinations - A New Level Of Effectiveness

allen — Thu, 08 Jan 2009 01:14:24 GMT

Siemens Medical Solutions is solidifying its presence at the forefront of the market for computer-assisted reading tools in CT colonography by announcing the release of a new version of syngo Colonography PEV (Polyp Enhanced Viewing), an automated second reader tool for the visualization of lesions in the colon. The solution helps radiologists to detect polyp-shaped objects between 6 mm and 25 mm in size and can now be used both in clean-prepped and solid-liquid tagged protocols. With the new version, syngo Colonography PEV delivers the benefits of computer-assisted reading to a wider range of protocols commonly applied in CT colonography today, including stool tagging agents. The PEV tool is seamlessly integrated into the syngo Colonography CT application.

Foetal Dosimetry

allen — Thu, 08 Jan 2009 01:14:24 GMT

This patient was involved in a motor vehicle accident, while 35 weeks pregnant. Although exposure to the gravid uterus is to be avoided when ever possible, and only deliberately performed after careful weighing up of the pros and cons, McCollough et al conclude their recent Radiographics article with: “After comparing the doses from radiologic and nuclear medicine examinations with risk data from human in utero exposures, we have concluded that the absolute risks of fetal effects, including ch
