Bone marrow stem cells suspended in X-ray-visible microbubbles can help in treating peripheral arterial disease (PAD) patients by increasing the number of blood vessels, according to research presented at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla. this week.
Naviscan has reported that its Positron Emission Mammography (PEM) scanner will be utilized in pre-clinical and translational research for the development of radiotracers by Richard Wahl, MD, professor of radiology and nuclear medicine at the Johns Hopkins School of Medicine in Baltimore.
The National Institutes of Health (NIH) convened a panel Thursday to identify ways to increase the use and quality of colorectal cancer screening in the U.S.

CHICAGO—Radiologists can accurately diagnose acute appendicitis from a remote location with the use of a handheld device or mobile phone equipped with OsiriX mobile software, based on study results presented Monday at the 2009 annual meeting of the Radiological Society of North America (RSNA). The researchers are seeking to study this technology for other conditions that require an expedited diagnoses.
An Agency for Healthcare Research and Quality (AHRQ) literature review suggests that consumer health informatics engage consumers, enhance traditional clinical interventions and improve intermediate and clinical health outcomes.
Radiologists' workloads grew substantially in the past few years, with procedures increasing 7 percent and physician work relative value units increasing 10 percent from 2002-2003 to 2006-2007, according to research published in this month's Radiology.
Researchers may have found a way to combine imaging with chemotherapy in a single agent for the treatment of prostate cancer, according to data presented this week at the 100th annual meeting of the American Association for Cancer Research (AACR) in Denver.
Radiation oncology, cardiology, and orthopedics are employing advanced visualization applications to deliver effective treatment, track the progression of disease and plan surgical interventions.
In a development that researchers say could quell concerns about the value of costly CT scans to diagnose coronary artery blockages, the results from the CorE-64 study were published online Wednesday in the New England Journal of Medicine. The results confirm that 64-slice CT scans can correctly identify people with major blood vessel disease and that they are nearly as accurate as invasive coronary angiography. The initial findings from CorE-64 were presented at the 2007 annual American Heart Association’s (AHA) Scientific Sessions last November. The results released this week reflect the study’s updated data.
Colorectal adenomas, the precursor polyps in virtually all colorectal cancers, occur infrequently in younger adults, but the rate sharply increases after age 50. The study results, published online in Clinical Gastroenterology and Hepatology, further emphasize the importance of colonoscopies for the prevention of colorectal cancer beginning at age 50.

A new technique called personalized analysis of rearranged ends provides an accurate and specific way to monitor tumors by identifying personalized biomarkers from tumor DNA, according to a study published in the Feb. 24 issue of Science Translational Medicine.
An international study on CT perfusion imaging at 15 medical centers in eight countries, led by researchers at Johns Hopkins University in Baltimore, have enrolled the first dozen patients to figure out how well various imaging tests can measure the degree of blockage or narrowing in any particular artery and their use in predicting patients who need catheterization or angioplasty, or bypass surgery.
PET/CT with C-11 acetate has higher sensitivity compared to 18F-FDG imaging in detecting primary prostate cancer, local recurrence and apparent nodal spread of the disease in both the staging and re-staging patient populations, according to research presented at the 2009 Radiological Society of North America (RSNA) annual conference in Chicago earlier this month.
The problem of developing security mechanisms needed for management protocols and policy management of personal health information (PHI) remains largely unsolved, according to Gerald Masson, PhD, director of the John Hopkins University Information Security Institute, who spoke at an assembly hearing of the Health IT Standards Committee on Nov. 19.
Researchers have found recent evidence that shows the growth of external, off-hours teleradiology services (EOTS) has slowed in recent years, despite a significant increase in the number of radiology practices using those services between 2003 and 2007, according to a study in the November issue of the American Journal of Roentgenology.
In a presentation on Tuesday at the 2009 American Association of Physicists in Medicine (AAPM) meeting in Anaheim, Calif., researchers at Johns Hopkins University in Baltimore described the design of nanoparticles that can carry cancer-treating radioisotopes through the body and deliver them to selective tumors.
In MR angiography (MRA) of peripheral arteries, injecting contrast medium at a slow, balanced rate can alleviate contamination of veins in the calves while maintaining image quality, according to a multinational team of researchers from China and the United States. Their study, published this month in the American Journal of Roentgenology, suggests that it is possible to increase arterial visibility in the calf while signal-to-noise and contrast-to-noise ratios at higher levels are maintained.
Toshiba Medical Systems will support CorE 320, an international multi-center trial, beginning this month, to compare the effectiveness of 320-detector row dynamic volume CT to SPECT technology in identifying coronary stenosis.
3T MRI has found a sweet spot in musculoskeletal, neurological and breast imaging. Clinicians are reaping the benefits of high-resolution, high-quality images acquired at a higher field strength—
and more referrals.
Ziosoft, a provider of advanced visualization and analysis software for
medical imaging, is partnering with medical teaching institution, Johns
Hopkins University in Baltimore, to explore innovative applications for
cardiac CT and MR imaging.

The use of health IT to reduce rehospitalizations will be welcome but also disruptive, said Stephen Jencks, an independent consultant in healthcare safety during a Feb. 24 webinar on the potential use of health IT to mitigate rehospitalizations, sponsored by the Agency for Healthcare Research and Quality (AHRQ).
During the Health IT Standards Committee meeting on Feb. 24 in Washington, D.C., the Clinical Operations Workgroup sought to gather comments on proposed recommendations on implementation specifications for content exchange, vocabulary and code set standards for the Interim Final Rule of meaningful use.
In 2006, the Center for Devices and Radiological Health (CDRH), a branch of the FDA, began examining the number of medical device reports they received. Over the past two years, the number of submitted reports has increased, sparking a demand for the CDRH to make a move to electronic reporting.
A new hospital breaking ground usually isn’t breaking news. But the vision of patient care at one new facility, tentatively named Palomar Medical Center West (PMC West), is currently illegal under California state law.
