Patient survival influences new lung cancer staging system
Based on on a database with more than 100,000 submitted cases, modifications to the international system for staging non-small cell lung cancer promise to more closely reflect the connection between disease progression and the patient's prospects for survival.
Advantages of wide CT detectors outweigh disadvantagesMay 19th 2009
The new generation of wide CT detectors provides expanded coverage, allowing faster scans and even dynamic imaging of organs, including heart and brain. There are disadvantages, said Dr. Mathias Prokop, speaking May 19 at the 11th International Symposium on Multidetector Row CT, but these are minor in comparison.
Glazer calls 'invisible radiologist' to task, encourages molecular understandingMay 19th 2009
A smorgasbord of challenges face radiology but few present a greater threat than the “invisible radiologist,” said Dr. Gary Glazer, chairman of the Stanford University radiology department, who kicked off the 11th International Symposium on Multidetector-Row CT.
Ground-glass nodules merit scrutiny for differential diagnosisMay 16th 2008
Persistent ground-glass nodules in the lungs are worth a closer look, as they are highly associated with malignancy. Dr. Anne Leung offered an overview of how these lesions present on CT imaging at the 2008 Stanford International Symposium on Multidetector-Row CT in Las Vegas.
Benign mesenteric disease demands views other than axial CTMay 16th 2008
A comprehensive CT evaluation of the abdomen requires analysis of the mesenteric vasculature above and beyond the axial plane, according to Dr. Elliot Fishman, director of diagnostic radiology and body CT at Johns Hopkins University and Hospital.
Philips accelerates Brilliance iCT installationsMay 15th 2008
Philips Healthcare is stepping up efforts to deliver its ultra-premium Brilliance iCT to sites around the world. Jeffrey Studenka, Philips’ senior director for field marketing, told Diagnostic Imaging at the Stanford MDCT conference that the company now expects to have 50 of the 256-slice units installed by the end of 2008. This is about four times as many as company execs were predicting when they unveiled the iCT at RSNA 2007.
Lung cancer therapy response calls for new thinkingMay 15th 2008
CT multitasks in the lungs, serving as a tool for cancer screening, disease diagnosis, lesion characterization, and lung cancer treatment response. In a talk at the 2008 Stanford International Symposium on Multidetector-Row CT in Las Vegas, Michael McNitt-Gray, Ph.D., posited that CT can be used more effectively to assess treatment response in lung cancer patients, but clinicians must look beyond current response parameters.
Oral fluids may dilute contrast reaction risk in patients with kidney disordersMay 14th 2008
Logistical and reimbursement limitations dictate that most CT exams be performed on an outpatient basis, making it difficult to manage contrast-related reactions, especially in patients with renal insufficiency. Oral hydration may be as effective as intravenous fluids for preventing contrast-induced nephropathy in some instances, but further study is needed.
FDA clears GE’s new CT scannerMay 14th 2008
As the exhibit floor at the Stanford International Symposium on Multidetector-Row CT was ready to open May 13, GE booth managers strategically placed signs announcing the FDA clearance of its new LightSpeed CT750 HD atop displays of the scanner’s components.
Siemens showcases dual energy software, applicationsMay 14th 2008
Siemens Healthcare cast its dual-source CT scanner Somatom Definition as the clinical pioneer of multienergy scanning, presenting its Optimum Contrast software as the means for improving dual-energy images created using injected contrast agents. Image optimization algorithms process data obtained at different energy levels -- 80 kVp to 140 kVp -- to create optimal image quality for the kinds of structures being displayed (soft tissue and vasculature, for example), according to the company.
Dual-energy CT catches subtleties of pancreatic massesMay 14th 2008
Faster and better visualization are the main reasons to use dual-energy CT for the assessment of pancreatic masses, according to a presentation at the Stanford International Symposium on Multidetector-Row CT in Las Vegas.
