Jude Dineley[email protected]Molecular ImagingDutch use shimming to enhance value of MRI-linac unitOnly a handful of groups are developing hybrid MRI-linac systems for cancer treatment, but interest in this area looks set to grow after researchers from the Netherlands showed that shimming allows a system to acquire images with good geometric fidelity for all static gantry positions.July 16, 2014Clinical NewsBidirectional scans can boost resolution of 3D imagesThe value of optoacoustic or photoacoustic imaging in preclinical research has been established, and German researchers are now working toward clinical translation of the technique. A new study shows a bidirectional scanning approach improves the elevational resolution of 3D images.June 12, 2014Clinical NewsEstimating dose for advanced mammographyNew conversion factors enable calculation of mean glandular dose resulting from contrast-enhanced digital mammography, and have been adopted for use in Europe and by the International Atomic Energy Agency, following pioneering work by researchers in the U.K.May 7, 2014Clinical NewsPhase-contrast CT boosts tissue contrastIn screening for breast cancer, conventional mammography carries a finite risk of false positives and undetected lesions. Phase-contrast CT is a promising candidate that exploits variations in x-ray phase, instead of absorption, to produce superior soft-tissue contrast to conventional CT imaging.April 28, 2014Clinical NewsProton CT can improve stopping power accuracyThe fine-tuning of proton therapy plans to maximize tumor dose and minimize dose to healthy tissue is held back by significant uncertainties in the stopping power estimates used to calculate proton range. Danish researchers have boosted the accuracy of these estimates with an image reconstruction technique combining x-ray cone-beam CT data with a proton CT scan.April 6, 2014Molecular ImagingFocused ultrasound releases cancer drugIn a step toward the clinical use of ultrasound-mediated doxorubicin delivery, a joint French-Dutch research project has identified the ultrasound characteristics required to release the chemotherapy drug from temperature-sensitive liposomes.January 8, 2014Molecular ImagingTargeted LET-painting can improve tumor controlSteering high-linear-energy-transfer (LET) radiation into hypoxic regions of a tumor could substantially increase tumor control, according to researchers from Denmark and Germany in an initial modeling study.November 6, 2013Molecular ImagingUltrasound imaging: No need to touchNoncontact ultrasound imaging, in which the transducer is separated from the skin by air, has been achieved in vivo by researchers. The group is cautiously optimistic about a clinical future for the technique, which uses a tightly focused high-intensity beam to generate tomographic images.September 25, 2013Molecular ImagingHybrid brain imaging technique adds temporal dimensionMRI/PET/electroencephalography hybrid scanning has been achieved for the first time by a group of researchers from Jülich in Germany, according to a recent article published online by the Journal of Magnetic Resonance, which describes the work being done and makes a case for multimodal imaging at 3 tesla and 9.4 tesla.February 25, 2013Molecular ImagingAdvanced segmentation cuts plan errors for PET-guided IMRTSignificant dosimetric errors in PET-guided planning of intensity-modulated radiation therapy (IMRT) can be avoided by using advanced segmentation algorithms, according to an article published in a September issue of Physics in Medicine and Biology. Use of these algorithms helps maintain patient safety and quality in a radiation oncology department.September 23, 2012Previous PagePage 3 of 4Next PageTop StoriesMRILow sexual desire manifests as dimorphic brain processing on fMRIMen and women with hypoactive sexual desire disorder (HSDD) show dimorphic brain processing on functional MRI, a new study has found.Emergency RadiologyJAMA: Radiology among least affected services in Ukraine warEnterprise ImagingAgfa secures agreement with Dublin hospitalCTUse CCTA to track vasculopathy risk in heart transplant patientsSponsor ContentJourney to the Cloud: A Snapshot of Market Progress - 22 May @ 7pm CET
