While a large retrospective study found that interstitial lung abnormalities (ILAs) were evident on 1.7 percent of computed tomography (CT) scans, researchers found that 43.9 percent of ILAs, including fibrotic ILAs, were not reported.

Will energy replace slices as CT battleground?
May 25th 2010In the wake of the slice wars, which saw CT scanners boom from four to 320 slices, a new battle will be fought, one focused on energy and spectral imaging. Photon counting, triple- and quad-energy systems, and a new breed of contrast agents are emerging drivers in the development of spectral CT, say some experts in topics scheduled for the Tuesday, May 18, ISCT session on Dual Energy and Spectral Imaging.
R&D shift seeks to leverage image quality to cut dose
May 25th 2010A dramatic shift in R&D toward patient safety has taken place in the CT industry, a shift most clearly seen in efforts to reduce patient radiation dose. Iterative reconstruction algorithms are a prominent fixture at the ISCT meeting this year, as they and their future development are increasingly seen as providing the means to cut dose, while maintaining or even boosting image quality.
Data for pediatric radiation dose scarce but solutions available, expert says
May 24th 2010Much is known about dose reduction and adult patients, but what about kids? The literature is scant, but that doesn’t mean solutions don’t exist, according to a presenter at the International Society for Computed Tomography conference May 21.
Dearth of data lowers the bar in debate over radiation and cancer
May 21st 2010Radiologists have come to expect rising demand for CT, which is why anecdotal reports of sudden and dramatic falls in CT volumes have sent a shudder through the community. All the more alarming is that the rumored drop-offs are coming at the request of patients who want nothing to do with CT because they fear its radiation will someday cause cancer. Instead they reportedly are demanding ultrasound or MRI because neither has ionizing radiation -- never mind that neither is indicated, nor, particularly in the case of ultrasound, has much chance of providing useful information.
Content-driven PACS may guide future diagnoses
May 21st 2010Efforts to interconnect information systems raise the possibility that different experiences from multiple sites might be pooled and the practice of medicine made better through a kind of collective wisdom. At the ISCT symposium, Sandy Napel, Ph.D., a Stanford professor of radiology and codirector of the Radiology 3D Laboratory, examined how diagnoses made on some patients might help clarify whether the same diagnoses apply to others.
Iterative recon marshals 'profound effect' on CT scanning
May 19th 2010Iterative reconstruction algorithms will have a “profound effect” on CT as the enabling technology for advances in image quality and patient safety, said Stanford radiology professor Geoffrey Rubin at the ISCT symposium on multidetector row CT.
Experts debate connection between CT and cancer
May 19th 2010Clinical studies examining the potential of CT exposure to cause cancer are under way, but it could be years or even a decade until the results are known. Even then, they may be inconclusive, say expert presenters at the ISCT symposium on MDCT.
Presenter asserts serum creatinine alone can’t assess kidney function
May 19th 2010While most physicians rely on serum creatinine levels to determine kidney function, it’s not the most reliable indicator, according to a nephrologist who presented at the International Society for Computed Tomography on May 18. Instead, he suggested providers look at the estimated glomerular filtration rate (eGFR). In acutely ill patients in particular look at the changing serum creatinine (sCR) levels and not the specific values or specific eGFRs, he said.
GE’s ASIR gains foothold in CT community
May 19th 2010GE Healthcare jumped ahead of competitors in the race to cut patient dose with the commercial release in 2008 of its Adaptive Statistical Iterative Reconstruction (ASIR), the first software to clean up CT images and, in the process, allow dramatic reductions -- up to 50% -- in patient radiation dose. In the first day of this year’s ISCT symposium, iterative reconstruction was hailed repeatedly as the leading solution to the hottest issue in CT patient safety.
Workstation session explores issues of policy and trust
May 18th 2010Three-D is all the buzz, as PACS companies struggle to include it in their products, if they haven’t already. But where this form of advanced visualization fits into the diagnostic process is still up in the air. Ironically, so are some of the everyday tools on which advanced visualization depends. Trust issues about the automation that makes sophisticated postprocessing viable are beginning to surface, just as progress in CAD offers new clinical capabilities.
ISCT contrast sessions explore new technology, CIN risk factors
May 18th 2010What do you get when you mix contrast delivery with computer technology? Dr. Dominik Fleischmann, director of CT at Stanford Hospital and Clinics kicks off a session at the International Society for Computed Tomography conference starting May 18 on contrast medium delivery and image enhancement. He will focus on how power injectors are starting to act as computers.
Will energy replace slices as CT battleground?
May 17th 2010In the wake of the slice wars, which saw CT scanners boom from four to 320 slices, a new battle will be fought, one focused on energy and spectral imaging. Photon counting, triple- and quad-energy systems, and a new breed of contrast agents are emerging drivers in the development of spectral CT, say some experts in topics scheduled for the Tuesday, May 18, ISCT session on Dual Energy and Spectral Imaging.
Combined probes in PET scan reveal immune system cell function
May 17th 2010A commonly used probe for PET scanning and a new probe developed by researchers at UCLA reveal different functions in diverse cells of the immune system, providing a much clearer picture of an immune response in action.
R&D shift seeks to leverage image quality to cut dose

Iterative reconstruction algorithms are a prominent fixture at the ISCT meeting this year, as they and their future development are increasingly seen as providing the means to cut dose, while maintaining or even boosting image quality.
Talks on present and future CT technology kick off ISCT symposium
May 14th 2010The last decade-plus has seen unprecedented development in all aspects of CT technology. Presenters will kick off the International Society for Computed Tomography symposium Tuesday morning May 18 looking at this evolution as part of the “Technology: Present and Future” session.
CT found effective for Dx lung collapse in women
April 29th 2010Using high-resolution CT scans to screen for lymphangioleiomyomatosis is cost-effective in women between the ages of 25 and 54 who don’t smoke and come to the emergency room for the first time with a collapsed lung, according to University of Cincinnati researchers.
Modifying technique cuts radiation dose for CTA
April 29th 2010Reduced or no “padding” during ECG-triggered coronary CT angiography results in a substantial reduction in radiation dose without affecting image quality and interpretability, according to a study in the April American Journal of Roentgenology.
Singapore meeting incorporates nuclear medicine update
April 13th 2010The annual joint scientific meeting of the Singapore Radiological Society and the College of Radiologists, Singapore, was expanded this year to include the Singapore General Hospital nuclear medicine update. This allowed a greater inclusion of topics pertaining to nuclear medicine and radiation oncology, with the theme of the meeting being “imaging and therapy in the area of molecular medicine.”
Multidetector CT reveals diverse variety of abdominal hernias
April 8th 2010Although most hernias involving the anterior abdominal wall or groin can be diagnosed easily by inspection and palpation, imaging is the principal means of detecting internal, diaphragmatic, and other nonpalpable or unsuspected hernias.1,2
