Ultrasound nears its potential in breast cancer

By Greg Freiherr



It’s been a long time coming. Nearly a decade has passed since ATL took a serious run at advancing the medical art of breast cancer diagnosis. The company, long-since absorbed by Philips Healthcare, developed a novel algorithm designed for its Ultramark 9 HDI, later adapted for its HDI 3000 and 5000.



The goal was to eliminate the need for at least some biopsies. In an effort to… Continue

Final rules in 2009 Medicare Physician Fee Schedule disappoint some, elate others

By James Brice



The 2009 Medicare Physician Fee Schedule reflects the recent tendency of the Centers for Medicare and Medicaid Services to propose stringent reforms for in-office imaging and independent diagnostic imaging facilities in the summer and decide against their implementation when the final MPFS rules are published in the fall.



This year, CMS deferred… Continue

CT colonography offers number one choice after failed colonoscopy

By Rebekah Moan



An Italian investigation suggests virtual colonography is a better follow-up test for failed colonoscopy than a double-contrast barium enema.



Dr. Lapo Sali of the radiodiagnostic section within the department of clinical physiopathology at the University of Florence and colleagues conducted a population-based screening program for colorectal… Continue

Brain imaging uncovers why people overbid at auctions



New York University neuroscientists and economists have combined functional MRI with behavioral economic research to discover why people tend to overbid for products sold at auction: fear of losing a social competition. The next step may be explaining irrational Wall Street behavior.



Functional MRI was used to examine brain activation patterns while volunteers played either an auction game with a… Continue

Study evaluates stack mode viewing techniques

by Douglas Page



In the absence of satisfactory 3D viewers, most volumetric medical data is currently viewed as stacks of 2D slices. Yet little research has been conducted on stack mode viewing techniques.



A recent study from Canada evaluated three interaction techniques for scrolling stack mode displays of volumetric data:



* Two techniques used a scroll-wheel mouse.

* One used only the… Continue

Core needle biopsy proves safe for patients taking anticoagulants



Radiologists can breathe easier about the risk of patient bleeding and bruising when performing core needle breast biopsies on women who take daily anticoagulant aspirin or therapeutically-in-range warfarin, according to a new study.



In the past, patients were advised to cease anticoagulation therapy for one week before undergoing core needle breast biopsy. Radiologists found, however,… Continue

Colonoscopy proves cost-effective for younger patients but questionable in older ones

Rebekah Moan



Conducting colonoscopies for people in their midfifties saves money, but screening in those older than 75 may not be beneficial, according to a government policy group.



Research presented in September at the 2008 American College of Gastroenterology’s meeting showed that screening for colon cancer at age 55 would save at least two dollars for every… Continue

Product Review: 2View Mammography Specimen Container

We had the pleasure to recently review the 2View Mammography Specimen Container. Thanks to the team at 2-View for this opportunity.







The product

As mentioned on 2View's website, partial mastectomy specimen handling has challenges. Compression, lack of orthogonal views, and manual manipulation of the specimen are issues with specimen radiography. When there is no margin for error, a new device such as 2View mammography specimen container is a great… Continue

CT's impact in diagnosing appendicitis depends on clinical likelihood



Clinical experience shows that diagnostic CT reduces the incidence of negative appendectomies. Those skeptical about the application's safety, however, may find ammunition in a recent prospective study that suggests CT may be unnecessary when appendicitis is unlikely.



Dr. Robert O. Nathan, an acting assistant professor of radiology at the University of Washington in Seattle, and… Continue

Deep Vein Thrombosis Evaluation May be Performed More Cheaply per JAMA Article

A simple ultrasound scan works as well at spotting deep vein blood clots as a costly and time-consuming technique requiring more advanced equipment, Italian researchers said on Wednesday.



The finding gives emergency room doctors and hospitals lacking expensive ultrasound machines an easier way to check for the clots that can kill, said Enrico Bernardi of the Civic Hospital in Italy, who led the study.

"Until this study nobody knew if the two techniques were equally effective and… Continue

SeekRadiology: 2008 October



There are all sorts of search engines that are pertinent to the field of diagnostic imaging such as Goldminer, RadiologySearch and YottaLook. But these are all on a different server with different URL’s so if you want to use all of them at once, you have to have 3 or more windows or tabs open. SeekRadiology is bound to solve just that problem. It is not a search engine in itself, but it is a clever use of some old HTML and new Java Script to… Continue

Surf the web for your mental health

Greg Freiherr



Every day, I'm getting better at making tough decisions. I know this because searching the Internet stimulates the parts of my brain that control decision making and complex reasoning. Scientists at the University of California, Los Angeles found this out using functional MRI on computer-savvy middle-aged and older adults while they surfed the web. I extrapolated.

Functional MRI establishes link between brain receptor activation and obesity

Kathryn Madden, science administrator, Oregon Research Institute



Using brain imaging and chocolate milkshakes, scientists have found that women with weakened "reward circuitry" in their brains are at increased risk of weight gain over time and potential obesity. The risk increases even more for women who also have a gene associated with compromised dopamine signaling in the… Continue
