RSNA

RSNA newbie Real-Time Tomography launched at this year’s meeting a new image processing and enhancement software library for digital mammography.

Using sophisticated mapping technology, census data, and state cancer registry statistics, researchers from Georgia established a link between the presence of Mammography Quality Standards Act-certified mammography centers and lower death rates from breast cancer.

Carestream Health showed at the RSNA meeting a work-in-progress upgrade to its PACS that will allow cross-site reading through a unified global work list.

SuperSonic Imagine returned to the RSNA exhibit floor with FDA clearance to market its Aixplorer ultrasound system in the U.S.

CT vendors have been talking for months about the potential of iterative reconstruction as the next big thing to substantially reduce the worrisome radiation dose patients are exposed to during multislice CT imaging. Now they have results of a large multicenter cohort study to add substance to their enthusiasm.

“Hedge” statements were found in nearly a third of radiology reports using a computer-based review system described in an award-winning paper presented Tuesday at the RSNA meeting.

MRI is the best method to assess breast cancer tumor size prior to surgery and after chemotherapy, according to findings from the American College of Radiology Imaging Network trial 6657. Size on mammography does not correlate with true residual disease in patients treated with neoadjuvant chemotherapy and thus MRI is the best modality, the researchers said.

Radiation from mammography screenings may increase the chances of developing breast cancer for women at high risk, according to findings presented Tuesday at the 2009 RSNA meeting.

Findings of a study by California researchers suggest MR imaging could be a highly accurate tool in the detection of placenta accreta, the leading cause of death in women directly before or after childbirth

IT products ready for market and ones nearing commercial release punctuated the Merge Healthcare booth at the RSNA meeting. Two works-in-progress vied particularly well for the attention of visitors. One is the eFilm for iPhone, an image-enabled supplement to the electronic medical record. The second is the company’s FusionWeb Patient Access Portal, which delivers an Internet-based means for web-savvy patients to manage appointments, update records, receive appointment reminders, and view reports.

Despite growing concern over CT-related radiation exposure, measuring cumulative exposure from CT imaging in a standardized or formal way is not part of routine practice for ordering physicians in the emergency department, according to a presentation this week at the 2009 RSNA meeting.

To prevent errors and misunderstandings, referring clinicians and radiologists must show more restraint when using abbreviations, a U.K. study has found.

CMC-001, an investigational MRI liver contrast medium, may be at least a partial answer to reducing the long imaging times that have frustrated patients and encouraged radiologists to look for imaging alternatives to aid diagnosis of hepatocellular carcinoma and colon cancer metastases in the liver. A phase III trial indicates it is as sensitive as a gadolinium-enhanced MRI for detecting colon cancer metastases, but at the cost of lower specificity.

Siemens brought two blockbuster MR offerings to the RSNA meeting this week: the 3T Skyra and 1.5T Aera. The two new products, works-in-progress pending FDA clearance but scheduled to begin shipping by mid-2010, promise a productivity lift through their patient-friendly bores, measuring 70 cm wide, and automation that simplifies complex scan tasks.

GE Healthcare unveiled at RSNA 2009 a software technique that uses low-frequency sound waves in combination with MRI to measure the elasticity of liver tissue as an indicator of disease.

Philips Healthcare executives believe the MultiTransmit parallel RF (radiofrequency) technology built into the company’s flagship 3T scanner will help make 3T a clinical workhorse.

Universal x-ray screening of tuberculosis has limited value, carries potentially adverse effects for patients, and creates an unnecessary cost burden, according to a study presented Monday at the 2009 RSNA meeting.

Siemens unveiled a new information technology at RSNA 2009: software that promises to do the tedious and time-consuming tasks involved in reading MR and CT exams. The new product, a work-in-progress pending FDA clearance, is an outgrowth of the syngo platform that Siemens has used for years to provide consistency in data processing among its modalities.

Full-field digital mammography significantly increases the cancer detection rate for women younger than 50 years, according to a study presented Monday afternoon at the RSNA meeting.

Digital mammography plus MRI is the most clinically effective strategy for screening women carrying a genetic mutation known to increase the risk for breast cancer. However, unless the cost of breast MRI decreases substantially, the modality doesn’t translate as cost-effective, according to a study presented on Tuesday at the RSNA 2009 meeting.

Adding noncontrast and delayed-contrast series to abdominal/pelvic CT examinations appears common in routine clinical practice and represents a potential public health danger with no associated clinical benefit, according to a presentation Monday afternoon at the 2009 RSNA meeting.

A new Irish study has highlighted an alarming lack of knowledge among clinicians about radiation exposure and its potential risks.

Radiologist Dr. Richard M. Chesbrough has taken an in-depth look at outpatient imaging services in Southeast Michigan, and the resulting picture is not pretty

Many radiologists have already viewed clinical images on their iPhones, but a study by researchers at Weill Cornell Medical College finds that there are plenty of other applications, ranging from study aides to clinical data lookups, that may be of value to practicing imagers.

DR Systems, an independent provider of medical information management systems, debuted a new image management system based on cloud computing Monday afternoon at the 2009 RSNA conference.

The number of unidentified, not corrected errors in radiology reports of spine MRIs is significantly higher than that of corrected errors, according to a study presented at the RSNA meeting on Monday.

Imaging suite dashboards that incorporate business intelligence to automate more steps could speed up and improve imaging processes, according to a Monday presentation at the RSNA meeting.

Developing a structured and rigorous peer-review quality assurance process that involves ongoing case presentations, open discussion, and consensus opinions can help to decrease perception errors and improve the interpretive skills of breast imagers, according to radiologists at Beth Israel Deaconess Medical Center in Boston.

Preoperative meniscal extrusion and the severity of cartilage loss and bone marrow edema can be trusted to predict the outcomes of arthroscopic partial meniscectomy in middle-aged and elderly patients.

If it’s round, has a hole in it, and isn’t a bagel or donut in the break room, chances are it’s a CD brought into the practice by a patient. According to Dr. Bradley Erickson from the Mayo Clinic in Rochester, MN, the use of compact discs to transfer diagnostic imaging data has seen a steady increase over the past decade.
