Paula GouldBreastResearchers take a 3D approach to breast densityCanadian and U.S. researchers have determined how measurements of volumetric breast density can be obtained from digital mammograms. The method builds upon previous work that allows the breast thickness to be determined precisely -- a key challenge when working in 3D.July 1, 2010Radiation Oncology/TherapyRadiation therapy markers may have role in drug deliveryGiven the proximity of inert implants such as fiducial markers and spacers to the target tumor, why not make more use of these devices? Researchers from Boston suggest they can be used to deliver radiosensitizing drugs or cytotoxic agents in situ, possibly improving efficacy without increasing radiation dose.January 24, 2010Radiation Oncology/TherapyOptical sensor tracks radiotherapy treatment site breast motionPostsurgical radiotherapy is an effective way of preventing breast tumors from reappearing, but the downside is the mismatch between ideal treatment plans and the doses actually delivered. Although conformal methods of delivery could address this issue, switching delivery techniques raises another potential problem: Will breast motion compromise the accuracy of a highly targeted radiotherapy regimen?November 25, 2009Radiation Oncology/TherapyCarbon ion therapy: To gate or not?When irradiating pancreatic tumors with carbon ions, respiratory gating may not provide much added benefit, according to research conducted at the National Institute of Radiological Sciences in Chiba, Japan.October 26, 2009Radiation Oncology/TherapyCan VMAT top IMRT for glioma treatment?Intensity-modulated radiation therapy (IMRT) makes it easier to target brain tumors while reducing dose to critical structures nearby. But can volumetric-modulated arc therapy (VMAT) do even better? A retrospective planning study from Canada has revealed the pros and cons of making the switch.September 17, 2009Radiation Oncology/TherapyVMAT bests IMRT for prostate cancer treatment timeIn terms of dosimetric accuracy, volumetric-modulated arc therapy (VMAT) is comparable to step-and-shoot intensity-modulated radiation therapy (IMRT), but VMAT cuts treatment time considerably, according to research from Memorial Sloan-Kettering Cancer Center.August 23, 2009Radiation Oncology/TherapyBreast IMRT without the overspillAn alternative intensity-modulated radiation therapy (IMRT) planning approach spares healthy structures from small, but significant, levels of radiation. IMRT has been recognized as a promising way to prevent breast cancer recurrence in patients who have opted for conservative surgery. Researchers in Alabama have devised a beam arrangement that delivers the benefits of IMRT, but without upping the low-dose overspill.March 2, 2008Radiation Oncology/TherapyGood vibrations stave off blood-borne diseasesA therapy based on pulsed laser irradiation could selectively destroy viruses and bacteria without damaging healthy cells. Researchers from Arizona State University in Tempe asked what would happen if viruses and harmful bacteria were excited in the same manner by a pulsed laser. Could the unwanted micro-organisms be forced to shake themselves to pieces without harming useful cells?February 10, 2008Page 1 of 1Top StoriesISMRM 2024ISMRM: Communication, multidisciplinary engagement key to pediatric MRICommunication and engagement with child-life specialists are factors in successful MR imaging for children, according to an ISMRM presentation.ISMRM 2024ISMRM: Novel visualization techniques show possible concussion damage from boxingISMRM 2024ISMRM: 'Reinventing' an MRI safety protocolISMRM 2024ISMRM: Technologist inexperience leads to MRI accidentsSponsor ContentWe care about what you think.
