French researchers develop handheld probe for SLN detection
June 17, 2008 -- NEW ORLEANS - Researchers from France have developed a handheld gamma camera to perform lymphoscintigraphy for sentinel lymph node (SLN) localization in breast cancer. They presented details of the device and results of a prospective clinical study comparing it with a conventional gamma camera during the 2008 SNM annual meeting.
Global radiation dose higher than necessary
June 3, 2008 -- Initial results of a multinational research study on x-ray quality control and patient dose conducted by the International Atomic Energy Agency (IAEA) reveal that up to 50% of x-ray exams performed in less developed nations are of substandard quality. What's more, many patients in these countries are being exposed to unnecessary radiation doses due to the need to repeat procedures.
DW-MRI shows value in RTP for head and neck cancer
June 3, 2008 -- A pilot study presented at the 2008 American Association for Cancer Research (AACR) meeting is the first to demonstrate the value of diffusion-weighted MRI for nodal staging in head and neck squamous cell carcinoma, according to investigators from Belgium.
ASCO news: Selenium use does not interfere with radiotherapy
June 2, 2008 -- CHICAGO - German researchers reported that use of the nutritional supplement selenium in women who are diagnosed with gynecological cancers does not appear to compromise the effectiveness of radiation therapy. The findings could be good news for patients taking selenium for its antioxidant properties.
VC radiation dose holds steady overall despite dose modulation
June 2, 2008 -- The radiation dose from virtual colonoscopy (VC) hasn't dropped much since the introduction of dose modulation software on CT scanners, largely because VC providers use it only half the time, according to a new study from the Netherlands, which also demonstrated significantly lower doses for VC screening protocols compared to daily practice protocols.
MRI outperforms MDCT in endoleak detection
May 30, 2008 -- Multidetector-row CT may soon find itself in competition with MRI for the imaging of endoleaks after endovascular repair (EVAR) of abdominal aortic aneurysms. Researchers found that MRI combined with a high relaxivity contrast agent had "significantly high sensitivity" for endoleak detection after EVAR when compared with MDCT.
Speech recognition shrinks report turnaround time
May 29, 2008 -- Speech recognition technology showed its worth in a study from Helsinki University Central Hospital in Finland, where report turnaround time was reduced by more than 80%. Study results were presented at the 2008 Society for Imaging Informatics in Medicine (SIIM) meeting in Seattle.
Ultrasound contrast boosts prostate biopsy yield
May 22, 2008 -- ATLANTIC CITY, NJ - Prostate biopsy guided by contrast-enhanced color Doppler ultrasound is superior to systematic biopsy in a screening setting, according to research presented at the Leading Edge in Diagnostic Ultrasound conference this week.
Automated polyp measurement cuts variability
May 21, 2008 -- A new study from the Netherlands found that manual polyp measurements in virtual colonoscopy were a bit more accurate than an automated process based on polyp protrusion measurements. The automated scheme still came out ahead, however, because it eliminated interobserver variability.
Small lung nodules vex dual-energy DR, study says
May 1, 2008 -- European researchers found no statistically significant benefit in the use of dual-energy digital radiography (DR) compared with conventional DR for detecting pulmonary nodules. The predominance of small lung nodules in the multicenter study may have exceeded the ability of dual-energy DR to detect them, they wrote.
