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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
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. Read More
Ground-glass nodule features on CT reveal malignancy risk
April 29, 2008 -- Researchers are peering through a proverbial glass, darkly, to study the features of ground-glass opacities (GGOs). GGOs are being detected with increasing frequency as more thin-section CT lung scans are performed to check for cancer in smokers and former smokers. Distinguishing benign from malignant GGOs is a hit-or-miss task for CT, one that could potentially improve if researchers are able to find reliable signs of malignancy or benignity, thereby reducing the need for invasive biopsy.

Open-source software delivers 3-way (PET/CT/MR) image fusion
April 25, 2008 -- There is a growing tendency for MR images to be viewed in combination with PET and/or CT in the quest for more accurate diagnoses of complex diseases. While hybrid PET/MR machines have yet to reach the market, a new open-source software application offers radiologists a way to create three-way PET/CT/MR image fusion. Read More
