Research presented at RSNA 2007 bolsters the role of MR imaging for preoperative surgical planning in patients with known breast cancer and in working up the challenging invasive lobular carcinoma.

The use of multislice CT angiography has increased detection of vascular injury in patients suffering head and neck trauma, prompting debate on whether whole-body screening or focused attention on the head and neck is more useful. Both methods had their proponents at an RSNA session on emergency radiology.

Diffusion-weighted MR imaging could one day become a routine exam for noninvasive characterization and staging of uterine tumors, replacing unnecessary catheter or surgical biopsies, according to several studies released Sunday at the RSNA meeting.

The RSNA has decided to eliminate ultrasound as a separate subspecialty category from its annual meeting’s scientific paper program in favor of an organ-based and clinical subspecialty-based approach. The move was received with mixed reactions by radiologists and sonologists.

Toshiba America Medical Systems has been talking for years about the development of a 256-slice CT. This morning, the company outdid itself, introducing a 320-element detector onboard its FDA-cleared Aquilion One. The announcement came as the exhibit floor opened, just hours before Philips Medical Systems unveiled a 256-slice CT, its Brilliance iCT.

Researchers from Ohio have found huge national discrepancies in waiting times for mammography. Women in the southern states fare much worse than their sisters in other regions.

A study from the Midwest that tracked the effects of converting from traditional transcription to voice recognition software indicates the automated approach is more accurate. The new approach also contributed to an impressive improvement in report turnaround time compared with manual report preparation.

RSNA newcomer Parascript is demonstrating at the RSNA meeting this week algorithms its executives claim could dramatically reduce false positives in mammography computer-aided detection. AccuDetect software could cut false positives by 60% to 80% below those typically encountered in mammography CAD, according to Yuri Prizemin, Parascript director of product marketing.

CT angiography of the lower extremities can be incorporated into whole-body CTA with a reduced contrast load but no reduction in image quality, according to research presented by Dr. Bryan Foster of the Boston University School of Medicine.

A radically redesigned CT platform unveiled by GE Healthcare at the RSNA meeting produces images of soft tissue that rival those taken using MR, according to GE executives, who are framing the platform as a wholly new breed of CT scanner.

A newcomer to the RSNA exhibit floor has introduced an all-in-one PACS solution with a beginning list price of just $15,000. But while QStar Technologies may be new to the annual Chicago meeting, it is a 20-year veteran of the IT business and a mainstream supplier of storage equipment to PACS vendors.

Practitioners can minimize radiation exposure during interventional procedures by following 10 easy steps, according to Dr. Navnit Kumar, a radiologist from Leeds Teaching Hospitals in the U.K.

Of the 6000 scientific abstracts submitted to the RSNA this year, four major areas stand out, according to Dr. Gerald Dodd III, chair of the RSNA’s scientific program committee.

In keeping with family tradition, my niece has entered the radiology business. She is getting ready for her first RSNA meeting and asked me, “As a potential customer, what would you want to see or hear at our booth this year?”

Slice wars erupted nearly a decade ago with the introduction of quadslice CT scanners. Since then, it's been one battle after another, as the industry jumped to eight slices per rotation, then 16, up to 32 and 40, back to 16 (with generators of varying power), then 64. Along the way, semantic skirmishes have broken out over what was a slice and whether multislice CT should be called MD (multidetector) CT.

Every modality other than ultrasound has siting requirements, sometimes big ones; cardiac cath labs and angio suites, are examples. But even the largest sonography systems can be wheeled from one room to another. Some can fit in the palm of your hand. There are trade-offs, to be sure. These nano scanners don't have much display space, and the computing engine can't compare to those on cart-based systems. But the market wants portability, the more the better, in some cases.

This year has been a miserable one for the makers of PET/CT units, so miserable that one vendor-Hitachi Medical Systems of America-has stopped marketing its hybrid scanners. Others are struggling under the weight of a plunge in sales of some 30% compared with the same periods last year.

Breast MR is approaching celebrity status. A raft of expert opinions, notably from the American Cancer Society, has established MR in public and professional minds as a leading means to diagnose cancer among patients at high risk and possibly even among patients in the general population.

Three-D reconstructions are routinely used in the imaging of many organ systems. Not only do referring physicians and patients like the volume-rendered images, but radiologists are finding the inclusion of coronal and sagittal reformats imperative to making the most confident diagnoses. The use of advanced imaging over the last year has become important in several organs, mainly the heart/chest (Figure 1) and the abdomen/pelvis.

The onslaught of faster, smaller, more precise, and more portable ultrasound imaging technology continues. Nearly three dozen RSNA exhibitors will be showing ultrasound scanners whose portability has lately crowded onto center stage along with image quality and once optional capabilities, such as 3D/4D.
