German study confirms image quality of hybrid PET/MRI
January 25, 2012 -- Researchers have provided further evidence that hybrid PET/MRI systems can offer "uncompromised MR image quality" and a "high accordance" between PET/MR and PET/CT in a new study published online 17 January in the European Journal of Radiology.
Turks take delight from MRI's success in tularemia
January 24, 2012 -- When three outbreaks of tularemia occurred in northeastern Turkey in 2004 and 2005, Europe was stunned at the chilling prospect of a little-known infectious disease that can spread so rapidly from animals to humans. Now radiologists are using MRI to provide valuable clinical information in complex cases.
'Magic mushroom' trips point to new depression drugs
January 24, 2012 -- LONDON (Reuters) - The brains of people tripping on magic mushrooms have given the best picture yet of how psychedelic drugs work, and British scientists say the findings suggest such drugs could be used to treat depression.
MRI lung perfusion looks set for broader clinical use
January 23, 2012 -- Contrast-enhanced MRI pulmonary perfusion should be used in a broader clinical area, in part because the modality can be performed quickly, even in critically ill patients, but optimal temporal resolution and contrast-to-noise ratio are both necessary to achieve appropriate perfusion imaging of the lung, according to researchers.
MRI shows potentially grave extracardiac findings
January 19, 2012 -- Cardiac MRI finds significant numbers of extracardiac findings in patients with suspected heart disease, and as many as 20% are potentially serious, according to a Swiss study in European Radiology. The prevalence of extracardiac findings has been investigated using CT but less with MRI.
Fetal MRI can complement prenatal ultrasound
January 17, 2012 -- MRI is proving useful in the prenatal diagnosis and evaluation of complex fetal thoracic pathologies, and is invaluable in assisting surgical planning where complicated anatomical abnormalities exist, Irish radiologists have discovered.
MRI of limited use in C-spine imaging of whiplash patients
January 12, 2012 -- Swiss researchers have concluded that 1.5-tesla MRI provides "only limited evidence" of specific changes to the cervical spine and surrounding tissues in patients with acute symptomatic whiplash injury, according to a study published online December 20 in Radiology.
'Wait-and-see' OK if rectal CA responds completely to chemoradiation
January 3, 2012 -- NEW YORK (Reuters Health) - Patients with rectal cancer who have a complete clinical response to chemoradiation can be managed without surgery if they are monitored closely, according to Dutch researchers who used MRI and endoscopy to assess the patients' clinical response.
4D MRA progresses in cerebrovascular diseases
December 30, 2011 -- Time-resolved, or 4D, MR angiography (MRA) seems to be making rapid advances. The development of parallel-imaging techniques and hardware improvements such as gradient performance have enabled time-resolved MRA acquisition, which provides dynamic information at a feasible temporal resolution.
3D matches 2D MRI for knee osteoarthritis, but in less time
December 27, 2011 -- Three-dimensional fast spin-echo MRI can achieve "moderate to almost perfect agreement and high accuracy" compared with routine 2D fast spin-echo MRI for evaluating knee osteoarthritis, but in 30% less time, according to a study presented at the recent RSNA 2011 meeting in Chicago.
Cardiac MRI beats SPECT in detecting coronary heart disease
December 26, 2011 -- Cardiovascular MRI is more accurate than SPECT for diagnosing coronary heart disease, according to the results of a prospective U.K. trial comparing the two. Authors of the study, published online on 23 December in Lancet, say their results indicate that cardiac MRI should be adopted more widely.
Imaging illuminates athleticism of Canarian wrestlers
December 21, 2011 -- Canarian wrestling may be a fairly specialized and small-scale sport, but the physical prowess of its athletes has come under intense scrutiny from a group of Spanish researchers. Their findings were presented at the recent Euroecho and Other Imaging Modalities conference in Budapest.
Eating disorders: Imaging can unearth hidden epidemic
December 14, 2011 -- Diana, Princess of Wales, is one of many people who have suffered in silence from life-threatening eating disorders. There are now around 70 million anorexia and bulimia sufferers worldwide, but award-winning research presented at the recent RSNA congress explains how radiologists can help.
MRI of hippocampus pinpoints early signs of dementia
December 7, 2011 -- Dutch researchers have discovered that hippocampal shape can predict dementia in the general population on average four years before clinical diagnosis. The shape varies from patient to patient, but similarities exist in certain "landmark points," delegates learned at last week's RSNA meeting.
Waking the dead: Virtual autopsies come under scrutiny
December 7, 2011 -- Just how accurate is a radiologist's diagnosis of cause of death compared with a coroner's? In 2006, the U.K. Department of Health commissioned a validation study to find out, and the findings were published online on 22 November in the journal Lancet.
PET/MRI surpasses PET/CT for some abdominal lesions
December 2, 2011 -- CHICAGO - PET/MRI can outperform PET/CT for lesion conspicuity and characterization in the abdomen, particularly in the liver, according to a study presented by Swiss researchers at the RSNA 2011 meeting.
