Efforts to raise awareness about the associated risks of CT-based radiation exposure and the need to keep children from receiving unnecessary scans seem to be achieving traction among healthcare providers, according to a study by Ohio researchers. Their findings suggest that such increased awareness may make referring physicians less likely to order imaging that involves ionizing radiation for young patients.

Alternating MRI with mammography every six months picks up breast cancers not identified by mammography alone for women at high risk, according to research out of the University of Texas M.D. Anderson Cancer Center in Houston.

An incidental finding of multiple sclerosis-type lesions during brain MRI is no fluke. A new study has found that some patients develop the physical symptoms of the disease within five years of the abnormalities’ discovery on MRI.

Despite encouraging earlier results, the much-awaited follow-up phase III DIAS-2 trial did not show any improvement in clinical response at 90 days for ischemic stroke patients who were given either of two doses of desmoteplase up to nine hours after the onset of symptoms of stroke compared with those who were given placebo.

Simple strategies, based on past experience with contrast-enhanced MRI for patients with compromised renal function, have helped radiologists and allied physicians bring the incidence of nephrogenic systemic fibrosis, a rare but deadly skin disorder, under control.

Siemens debuts breast ultrasound scannerSiemens dedicates MR scanner to breastFujifilm acquires RIS firmFujifilm unveils flat-panel DRNuance enhances decision support

Siemens underscored its commitment to women’s health with its introduction at RSNA 2008 of Espree Pink, a 1.5T scanner dedicated to breast imaging.

A new 3D, fast spin-echo MR sequence at 3T could one day help musculoskeletal radiologists perform a comprehensive evaluation of articular cartilage of the knee in only five minutes, according to researchers from Wisconsin and California.

For victims of psychological trauma, the challenge of suppressing painful memories may be rooted in the wiring of the brain, an ongoing study revealed at the RSNA conference Wednesday.

With the help of new robotic training, victims of stroke may be able to extend the narrow six-month window to regain their mobility, according to a recent study presented at the RSNA conference Wednesday.

A neuroradiologist, a neurosurgeon, and a radiological technologist explained to an RSNA audience how working together to analyze fMR scans has significantly helped them pinpoint hard-to-reach brain tumors and plan delicate surgery, resulting in improved surgical outcomes.

Adolescent gymnasts are developing a wider variety of arm, wrist, and hand injuries than previously described in gymnast-related medical literature, according to a retrospective review presented Monday at the RSNA meeting.

Results of a study by University of Vermont researchers suggest that 3T MRI should be considered as an alternative to CT in the evaluation of pediatric and young adult patients presenting to the emergency room with acute abdominal pain.

Philips Healthcare unveiled two MR scanners on the RSNA 2008 exhibit floor: one at 3T, the other at 1.5T. Both emphasize productivity and clinical value, albeit by different means.

Results from papers released Sunday at the 2008 RSNA suggest that a less rigid approach to treatment, coupled with knowledgeable practitioners and judicious patient selection can improve the commercial prospects of outpatient MRI-guided focused ultrasound ablation of uterine fibroids. There are caveats, though.

Breast MRI can have a positive impact on clinical decision making for African American women with newly diagnosed breast cancer, leading to wider excisions and mastectomies, according to a new study carried out in Ohio. Age is also a factor.

An aggressive, stealthy small breast cancer sub-type accounts for 10 percent of all breast cancers but half of all lesion-related deaths.

Patient comfort during MR and the efficiency of functional MR got a boost at RSNA 2008 with the unveiling by Resonance Technology of enhancements to its CinemaVision audio video systems and FuncLAB automated fMRI image data processor.

Preliminary results from American College of Radiology Imaging Network Trial 6657 show that MRI estimates residual breast cancer disease area better than clinical exams or mammography.

A new technique may help characterize diffusion anisotropy in the spinal cord in a clinical setting. Researchers have determined that using 3D single-shot diffusion-weighted stimulated echo-planar imaging in the cervical spinal cord results in higher resolution and less distortion than 2D single-shot diffusion-weighted echo-planar imaging.

Results from the largest and longest trial of its kind suggest that patients with intermediate and advanced hepatocellular carcinomas who undergo systematic treatment with three chemotherapeutic agents and arterial embolization plus imaging follow-up have better survival rates than those who undergo nonstandardized chemoembolization regimes.

The RSNA will underscore the unique achievements of Japanese imaging researchers in “Japan Presents,” a presentation of seven scientific papers focusing on diagnostic radiology. On Monday, Dec. 1, each paper will be introduced with the Japanese spin on ideas and concepts.

Themes emerging from breast imaging abstracts at the upcoming RSNA include the increased use of breast MRI, full-field digital mammography versus film-screen mammography, and more.

President-elect Barack Obama’s appointment of former Senate Majority Leader Tom Daschle to head the Department of Health and Human Services, combined with a commitment from insurers and a detailed plan from the chair of the powerful Senate Finance Committee, suggests strongly that healthcare reform will be a top priority for the new administration and the 111th Congress.

There is nothing like a little momentum to help the RSNA organizers present the latest developments in imaging research in the meeting’s scientific sessions. Everyone associated with imaging sciences from Beijing to New York City understands that presenting research in Chicago is an essential requirement for membership in this unique community.

Every day, I’m getting better at making tough decisions. I know this because searching the Internet stimulates the parts of my brain that control decision making and complex reasoning.

Using brain imaging and chocolate milkshakes, scientists have found that women with weakened “reward circuitry” in their brains are at increased risk of weight gain over time and potential obesity. The risk increases even more for women who also have a gene associated with compromised dopamine signaling in the brain.
