Kathlyn StoneRadiation Oncology/TherapyVMAT provides same treatment as IMRT in half the timeA study using volumetric modulated arc therapy (VMAT) for prostate cancer affirms the feasibility of the novel technique. Researchers from Memorial Sloan-Kettering Cancer Center compared VMAT with standard intensity-modulated radiation therapy (IMRT) using retrospective data from five patients who were prescribed a dose of 86.4 Gy.October 30, 2008MRIMRI magnet explosions warrant improved venting and inspectionsAt least five MRI magnets have exploded in U.S. healthcare facilities over the last 10 years, but the incidents have gone mostly unreported, according to Wlad Sobol, Ph.D., a medical physicist and professor of radiology at the University of Alabama at Birmingham (UAB) Health System.September 29, 2008Digital X-RayLarge CR study reveals wide variation in adult and pediatric protocolsA retrospective study of more than 40,000 computed radiography exams obtained from six University of Maryland departments suggests wide variations in protocols among hospital departments and slightly higher-than-necessary radiation exposure to patients, particularly children.September 2, 2008Nuclear MedicinePET dose-painting methods produce discordant resultsAs intensity-modulated radiation therapy becomes more sophisticated, oncologists are investigating new dose-painting methods to determine which areas of tumor target volume should receive additional radiation dose. But a new study indicates that two promising methods to guide dose painting actually produce sharply varied results.August 26, 2008Image ProcessingNew method reduces scatter in portable x-ray systemsResearchers at Emory University's Winship Cancer Institute and GE Global Research are collaborating on a software-based method for reducing scatter in portable systems. Tested on thorax phantom images, the algorithm reduced the x-ray signal by 50% to 100% without loss of image quality.August 21, 2008Radiation Oncology/TherapyOptions abound for radiation therapy QCQuality control is a vital issue in radiation therapy. A panel of experts recently discussed various approaches for radiation therapy quality control, ranging from peer reviews and data sharing to regulatory approaches and standards.August 18, 2008Radiation Oncology/TherapySurrogate organs stand in for lung tumors during fluoroscopic trackingWorking from the premise that other more visible anatomic features move in concert with lung tumors, researchers have developed a computer algorithm that uses these visible features as tumor stand-ins. In a feasibility study, the method localized the tumor position to an accuracy of within 1 mm and 2.5 mm.August 7, 2008Nuclear MedicineSPECT/CT mammography system produces first patient imagesHOUSTON - Duke University researchers have begun the first patient studies of a hybrid SPECT/CT mammography system, and the unit has several advantages over conventional breast imaging technology, according to their findings.July 29, 2008Radiation Oncology/TherapyAAPM speaker tackles topic of healthcare reformHOUSTON - Physics-based technology has had an undeniably positive effect on medical diagnosis and treatment, but that same technology is overused and its expense is contributing to America's exorbitant healthcare costs, according to the opening address at the American Association of Physicists in Medicine (AAPM) annual meeting.July 28, 2008BreastDigital breast tomosynthesis boosts reader accuracy, cuts recall rateDigital breast tomosynthesis (DBT) boosts radiologists' cancer detection rates compared to full-field digital mammography (FFDM) alone, according to a multicenter, multireader study that evaluted reader performance with DBT. For this study, a dozen radiologists at five clinics took part in the trial, which compared radiologists' cancer detection rates and screening recall rates using DBT.December 27, 2007Page 1 of 2Next PageTop StoriesClinical NewsBody composition analysis, MRI safety topped 2024's most read articlesWhile COVID and radiology salaries hit the top of AuntMinnie.com's Top 10 most-read posts of 2023, they rounded out the bottom of this year's list.Practice ManagementNeiman index outperforms Charlson for predicting imaging useWomens Imaging40% of women in their 40s forgo biennial breast cancer screeningRisk ManagementPractices must comply with the Corporate Transparency ActNuclear MedicineKidneys appear to tolerate Lu-177 treatments
