The CT660, which is already available in Europe, Latin America and Asia, distinguishes itself by its compact footprint combined with a modular design and low dose imaging. In addition, it is also one of the most energy efficient CT scanners available and has an “environmental design” that eases refurbishment and end-of-life recycling. The scanner itself is scalable from 32 to 128 slices through purchasable options and features automatic table positioning and a color 12-inch integrated gantry display monitor.

Warm Bath Ultrasound (WBU) is a new technology designed to produce 3D breast images in less than 10 minutes. It’s based on placing the breast in a warm water bath surrounded by multiple ultrasound transducers, allowing near instantaneous tomographic imaging of the tissue.  Although limited as a screening tool, ultrasound has proven...

Two lasers in the system are used to identify the presence of eumelanin in biopsy slices and a future version of the device may work directly without having to sample the mole. According to an article in Science Translational Medicine, “the ratio of eumelanin to pheomelanin captured all investigated melanomas but excluded three-quarters of dysplastic nevi and all benign dermal nevi.” From the press release: The tool probes skin cells using two lasers to pump small amounts of energy, less than that of a laser pointer, into a suspicious mole. Scientists analyze the way the energy redistributes in the skin cells to pinpoint the microscopic locations of diff...

The main result is that when radiologists review more mammograms per year, the rate of false positives declines. The stated purpose of the research*, published in the journal Radiology, was to see how radiologists’ interpretive volume — essentially the number of mammograms read per year — affects their performance in breast cancer screening. The investigators collected data from six registries participating in the NCI’s Breast Cancer Surveillance Consortium, involving 120 radiologists who interpreted 783,965 screening mammograms from 2002 to 2006. So it was a big study, at least in terms of the number of images and outcomes assessed. First — and before reaching any concl...

New wave of MRI-safe pacemakers set to ship to hospitals This week Medtronic will begin shipping to hospitals in the United States the first pacemaker approved by the FDA as safe for most MRI scans. For consumers, it is a significant step in what is expected to be a wave of new MRI-compatible implanted cardiac devices. But this is an example of one technology chasing another and the one being chased, the MRI scanner, is changing and is a step ahead of the new line of pacemakers. The pacemaker approved for U.S. distribution is Medtronic’s first-generation pacemaker with certain limitations, while its second-generation MRI-compatible pacemaker is already in use in Europe where approval for medical devices is not as dem...

This exemption exists to allow patients with access to a laboratory test, X-ray, or other imaging test at the same time and place as when patients are seeing their physician for an office visit. Less inconvenience and speeder diagnosis and treatment — what could be wrong with that? Much, say the critics, if it leads to overutilization and higher costs and doesn’t really represent a convenience to patients. This is the gist of two studies by staff employed by the American College of Radiology, published in the December issue of Health Affa...

Regulating medical devices and health care-related applications falls under the FDA’s jurisdiction. James Kendrick from JkOnTheRun spoke with Thompson, where he stated the following: The FDA is actively engaged in surveillance of various app stores to see if apps should trigger their involvement. Applications where a smartphone is connected in any way to imaging are under scrutiny, in particular. Any app that is used to transmit images to a medical facility requires FDA approval. By “various app stores,” Thompson is likely referring to the App store [Apple], Palm App Catalog [Web OS], App World [BlackBe...

But it has been many years since I was mandated to present a case. It seems that I’m not the only doctor exasperated by a pesky new barrier to patient care: Doctors in cubicles. An old friend and mentor, Dr. Richard Kovacs, now chair of the American College of Cardiology’s Board of Governors (and IU guy), has written about these same pre-certification barriers. Dr. Kovacs, being a professor and distinguished ACC official, kindly terms these obstructionists “radiology benefit managers” (RBMs).

Analyses of Medical Device Reports (MDRs) revealed device problems that appear to be the result of faulty design or use error that could be mitigated by the incorporation of additional safeguards. Between December 31, 1999, and February 18, 2010, FDA received 1,182 MDRs associated with the use of radiation therapy devices. Of these MDRs, linear accelerators accounted for 74%, radiation therapy treatment planning systems (RTP) accounted for 19%, and...
