The Diagnostic Imaging CT modality focus page provides information, videos, podcasts, and the latest news about industry product developments, trial results, screening guidelines, and protocol guidance that touch on the use of CT across the healthcare continuum, from various cancer screenings, such as lung and colon, to cardiothoracic imaging, to appendicitis, and more.

Combining clinical and CT features, adjunctive use of a classification and regression tree (CART) diagnostic model demonstrated AUCs for detecting clear cell renal cell carcinoma (ccRCC) that were 15 to 22 percent higher than unassisted radiologist assessments.

Radical gamma camera design promises to shake up nuclear medicine
December 19th 2005Israeli start-up Spectrum Dynamics has developed technology that can generate 10 times the sensitivity and double the spatial resolution of conventional Anger cameras, according to the company. Such dramatic increases raise the possibility of real-time imaging that shows the perfusion of one or more radiotracers through the myocardium introducing a radical change in the way cardiac patients are evaluated.
Top Siemens Medical exec details strategy behind Somatom Definition
December 19th 2005Siemens embraced customers 10 years ago as integral to its operations. When developing new technologies, engineers turn to customers early on to make sure their ideas have clinical value. This has led to some risk-taking, as evidenced by the introduction at the RSNA meeting of the Somatom Definition, a unique CT scanner that boosts speed and data collection by using dual detectors and tubes.
Incidental findings abound in cardiac CT imaging
December 9th 2005There is nothing incidental about the frequency of incidental findings seen in wide field-of-view 64-slice cardiac imaging. A study by Dr. Joshua Macatol, a radiology researcher at William Beaumont Medical Center in Royal Oak, MI, found that dozens of noncoronary findings may go undetected, however, as cardiologists focus on possible coronary artery disease.
Israeli firm promises to shake up nuclear medicine
December 5th 2005Imagine a gamma camera that generates video showing the perfusion of a radiotracer through the myocardium, the image brightening and dimming with the wash-in and wash-out of the tracer. Now imagine using a cocktail of radiotracers with each ingredient appearing on screen in a different color, together displaying a range of physiologic data.
Incidental findings abound in cardiac CT imaging
December 1st 2005There is nothing incidental about the frequency of incidental findings seen in wide field-of-view 64-slice cardiac imaging. A study by Dr. Joshua Macatol, a radiology researcher at William Beaumont Medical Center in Royal Oak, MI, found that dozens of noncoronary findings may go undetected, however, as cardiologists focus on possible coronary artery disease.
Unexpected tales abound in veterinary imaging
December 1st 2005Veterinary imaging specialists are broadening their horizons, making greater use of MRI, CT, and nuclear scintigraphy to supplement information from radiography and ultrasound examinations. The number and complexity of diagnostic tests on dogs, cats, and horses are growing steadily, and even live sharks and elephants have been imaged.
Siemens dual-source CT breaks with slice wars
November 27th 2005Siemens is radically changing the direction of its CT program with the introduction of its Somatom Definition. The new scanner, publicly announced Nov. 17 and featured Sunday at the RSNA meeting, packs two imaging chains in a single unit, generating 128 slices per rotation. But Siemens is downplaying the number of slices in favor of the speed of the scanner and how its use might change the clinical application of CT.
FDA clearances boom for second straight month
November 7th 2005The radiology industry appears to have bounced back from a bruising first half-year, during which the number of radiological devices cleared lagged far behind the pace set in the last two years. Thirty-three such devices passed FDA muster in September, just shy of the year’s highwater mark of 35 set in August.
CMS reins in nuclear medicine, multiple imaging costs
November 5th 2005The Centers for Medicare and Medicaid Services has decided to apply the federal physician self-referral law to nuclear medicine, reduce technical payments for cross-sectional imaging of contiguous body parts, and reduce payments on the Physician Fee Schedule, according to the final rule published by CMS this month.
Pediatric CT colonography sheds light on screening
November 2nd 2005Researchers have generally discarded the notion of virtual colonoscopy screening in children because colonic pathology in pediatric patients is rare and radiation exposure is a concern. A study from Argentina, however, has found that pediatric patients with suspected polypoid lesions of the colon can safely undergo diagnostic low-dose CT colonography. The low-dose protocol could have implications for adult colon cancer screening as well.
Specialists garner a bigger share of medical imaging
November 2nd 2005Diagnostic imaging's crucial role in medical practice is affirmed by the eagerness with which referring physicians have embraced diagnostic ultrasound, MR, CT, and nuclear medicine for an ever-lengthening list of clinical roles. Evidence now suggests that referring physicians appreciate diagnostic imaging so much, for both clinical and financial reasons, that a growing number are intent on making it their own. They are using exemptions in federal antireferral law that allow them to add high-tech imaging to their menu of in-office services.
Preventive imager laments fall of EBCT, spreads the blame
November 2nd 2005"Few radiologists understand preventive cardiology. They are enamored with less noisy pictures, and that's it. And few traditionally trained cardiologists care about coronary prevention and risk stratification of the asymptomatic person. Prevention falls to the primary-care doctor who, sadly, witnesses the specialists' apathy.
