Wayne Forrest[email protected]Clinical NewsPET/MR equals PET/CT for lung cancer, with far less radiationA pilot study conducted by German researchers and published in the August issue of Radiology suggests that PET/MRI provides diagnostic-quality images for assessing pulmonary masses in lung cancer cases, while cutting radiation dose by 75%.July 30, 2012Clinical NewsDWI-MRI shows tumor response after RF ablationUsing 3-tesla diffusion-weighted MRI (DWI), Swiss researchers found that apparent diffusion coefficient values of malignant liver lesions successfully treated by radiofrequency (RF) ablation may help radiologists monitor tumor response within six months of therapy, according to a study published online on 18 July in the European Journal of Radiology.July 26, 2012Clinical NewsPiB, FDG-PET change diagnosis for dementia patientsA new study by Dutch researchers adds evidence that PET imaging with carbon-11-labeled Pittsburgh Compound B (PiB) and FDG can lead to early diagnosis of Alzheimer's disease and differentiate between specific dementias, especially when previous diagnostic certainty is low.July 25, 2012Clinical NewsMRI shows fingolimod therapy helps multiple sclerosis patientsMRI scans have confirmed that the drug fingolimod reduced inflammatory lesion activity and brain volume loss in patients with multiple sclerosis. Results from the two-year, placebo-controlled trial were published online on 2 July in Archives of Neurology.July 9, 2012Clinical NewsMRI with gadolinium oxide particles finds more MS lesionsThe combination of gadolinium and ultrasmall superparamagnetic iron oxide particles in patients with multiple sclerosis (MS) reveals 51% more active lesions in MRI scans than gadolinium alone, French researchers report in the July issue of Radiology.June 26, 2012Clinical NewsDiffusion-weighted MRI provides boost for breast lesion detectionDiffusion-weighted MRI and apparent diffusion coefficient measurements help increase the specificity of breast MRI to more than 90% and provide faster imaging times in a noninvasive, nonionizing radiation way, concludes a new meta-analysis from France.June 19, 2012Molecular ImagingGerman team collects SNM Image of the Year awardGerman researchers have received this year's Image of the Year award at the recent Society of Nuclear Medicine (SNM) annual meeting for their research illustrating the effectiveness of a new radiopharmaceutical for treating digestive tumors.June 17, 2012Clinical News7T MRI helps predict multiple sclerosis in uncertain casesResearchers have achieved 100% positive and negative predictive values using 7-tesla MRI and a specialized scanning protocol to scan the brains of patients suspected of having multiple sclerosis (MS). The technique could possibly be applied to 3-tesla magnets, providing a means to diagnose MS patients without further invasive workup.June 3, 2012Clinical NewsMR elastography helps distinguish malignant, benign liver tumorsMR elastrography measures the properties of tissues through low frequency waves that induce stress, and is proving an effective way to distinguish between malignant and benign liver tumors, French researchers have found in a study published online in European Radiology.May 28, 2012Clinical NewsPET can prove effective for measuring tumor vascularityTo better assess the efficacy of drugs in early tumor response in clinical trials involving novel cancer therapeutics through PET imaging, researchers from several European centers have proposed a series of recommendations.May 1, 2012Previous PagePage 35 of 46Next PageTop StoriesWomens ImagingType of breast cancer features contribute to AI-mammography missesSpecific breast cancer characteristics contribute to AI-mammography misses -- and radiologists should keep them in mind when using the technology with mammography.UltrasoundForeign body imaging: X-ray overused, ultrasound underusedCTIR study: Keep aware of hydrophilic polymer embolizationCTRadiology mourns death of Ireland’s Barry KellyArtificial IntelligenceAI improves MRI diagnosis of prostate cancer
