Dinosaur vertebra fossil rises up in 3D from CT data
November 21, 2013 -- Noninvasive imaging techniques have long proved valuable for digging up the stories of fossils without damaging them. In a new study published online in Radiology, German researchers have gone a step further, making a carbon copy of a dinosaur vertebra using CT data and 3D printing.
House subcommittee mulls new approach to mobile app regulation
November 20, 2013 -- The debate over how best to regulate mobile medical apps reached the halls of the U.S. Congress this week as representatives sparred over a proposed bill that could strip the U.S. Food and Drug Administration of its authority to regulate many types of app software.
Radiology can benefit from mobile computing in myriad ways
November 15, 2013 -- Mobile computing technologies have the potential to reshape the practice of radiology, touching on areas such as interactions with referring physicians and other radiologists, image acquisition and transmission, education, and even patient care, according to an article in the December issue of Academic Radiology.
Ambient light rapidly degrades image quality on mobile devices
October 18, 2013 -- Maybe there's a reason radiologists work in dark rooms. A new study has found that the ability to interpret images correctly with mobile displays begins to decline if the devices are used in ambient light conditions brighter than the average office.
Mobile image viewer helps clinicians access images faster
October 3, 2013 -- Clinicians can access medical images much faster using mobile image-viewing software on Apple iPads without sacrificing diagnostic confidence or ease of use, compared with the use of traditional desktop-based software, according to researchers from the Mayo Clinic in Scottsdale, AZ.
iPads for radiology residents? Yes. Yes. Yes.
September 27, 2013 -- Should you equip your radiology residents with iPads? The answer is an unequivocal yes, according to a group from Boston, who found there were multiple benefits to using iPads and other mobile devices. However, residency programs should have a long-term vision for mobile-based education, they wrote in the October American Journal of Roentgenology.
FDA guidance on mobile apps offers clarity to developers
September 26, 2013 -- The U.S. Food and Drug Administration's release on Monday of its long-awaited final guidance on mobile medical applications was designed to address market confusion over its policy for regulating these apps. While some questions remain, the guidance offers app developers a path forward in determining how to secure regulatory clearance for their products.
MRI software opens views to blood-flow issues, stroke potential
September 25, 2013 -- When patients experience blood-vessel blockage that could lead to a stroke, correcting the condition as soon as possible can be critical. Vascular analysis technology firm VasSol believes its software, designed to quantify blood flow through any vessel in the body, can help with this and other conditions.
FDA mobile medical apps guidance includes radiology apps
September 23, 2013 -- More than two years after it issued a draft proposal, the U.S. Food and Drug Administration on Monday released its final guidance on the regulation of mobile medical applications for developers. Radiology-oriented apps figure prominently in the examples of mobile apps the agency said it intends to regulate.
Software yields 3D visual summaries of radiology reports
September 13, 2013 -- Medical imaging made a major leap forward when it moved from 2D images to 3D renderings. But the radiology department's primary product -- the radiology report -- is still based on archaic information that's 2D and text-based. A joint team from the U.S. and Singapore has developed a way to make radiology reports come alive -- in 3D.
No bones about it: Subtraction CTA uncovers cerebral aneurysms
September 12, 2013 -- Yielding high sensitivity and accuracy, an advanced visualization technique that automatically subtracts bone data from 320-detector-row CT angiography (CTA) scans could substitute for 3D digital subtraction angiography in detecting cerebral aneurysms, according to research published online in Radiology.
Software tool offers fast analysis of metastatic lesions
September 4, 2013 -- A semiautomated lesion management application within PACS software can provide reliable, consistent, and speedy segmentation of metastatic lesions in serial CT examinations of cancer patients, according to research published in the September issue of the American Journal of Roentgenology.
Interactive reconstruction of raw CT data: The next frontier?
August 23, 2013 -- The image interpretation process has come a long way since the days of static film. In the next evolutionary phase, radiologists may be given the ability to perform interactive reconstruction of raw CT projection data -- the sinogram -- according to Dr. Eliot Siegel of the University of Maryland.
MR analysis offers speedy brain tumor therapy response
August 21, 2013 -- An advanced MR analysis method can reveal new information on blood vessel type function, enabling physicians to determine within days whether brain tumor patients are responding to antiangiogenesis therapy, according to a report published online August 18 in Nature Medicine.
Postprocessing software boosts preop TAVI assessment
August 14, 2013 -- An automated postprocessing software application shows promise for improving the preoperative assessment of patients undergoing transcatheter aortic valve implantation (TAVI), a team of Paris researchers reported in JACC: Cardiovascular Interventions.
Meeting customer needs in the 3D lab: Part 2
July 10, 2013 -- In the second part of our series on implementing postprocessing requirements for radiologists and clinicians in the 3D laboratory, AuntMinnie.com provides 3D technologist Laura Pierce's suggestions for meeting the needs of clinicians.
Algorithm identifies misfiled chest x-rays in PACS
July 8, 2013 -- The adoption of PACS hasn't eliminated the problem of lost x-ray films, as any healthcare facility knows. But Japanese researchers believe they've found an answer through a computer algorithm that locates misfiled chest radiographs based on unique anatomical data, which they call "biological fingerprints," found in each x-ray.
Meeting customer needs in the 3D lab: Part 1
July 2, 2013 -- In this first installment of a two-part series on implementing postprocessing requirements for radiologists and clinicians in the 3D laboratory, AuntMinnie.com provides 3D technologist Laura Pierce's suggestions on how to address the needs of radiologists.
MDCT: iPad triggers rapid changes in radiology
June 19, 2013 -- For a relatively young technology, Apple's iPad has already wrought huge changes in radiology, affecting education, image viewing, and interactions with referring physicians, Dr. Elliot Fishman told attendees on Tuesday at the International Symposium on Multidetector-Row CT in Washington, DC.
Postmortem CT, 3D touchscreen table aid virtual autopsy
June 14, 2013 -- Postmortem CT can be an invaluable autopsy planning tool. With the help of a life-sized, 3D-enabled touchscreen table, pathologists can also view and manipulate images in 3D modes to locate pathology, perform virtual dissections, and decide on the best autopsy approach.
