Reader experience tied to CCTA accuracy
April 23, 2013 -- Training and experience wield a huge effect on reader accuracy in coronary CT angiography (CCTA) interpretation, and current minimum standards may not be sufficient, concluded a new study published online in the European Journal of Radiology.
Out of sight: CT know-how proves vital in orbital trauma
April 23, 2013 -- Full awareness of the CT features of orbital trauma, and the potential complications of damage to the eye, makes it possible to diagnose sight-threatening problems before permanent visual loss occurs, according to new research from a leading U.K. hospital group.
Healthcare in 2050: Digital technology to give power to patients
April 19, 2013 -- LONDON - The growth of smartphones and other digital technology will give patients much greater control over healthcare in the future, and patients will eventually decide on the hiring of researchers and medics, predicts Lucien Engelen, from the Nijmegen Medical Centre in the Netherlands.
Chest digital tomo can help reduce CT use, costs
April 18, 2013 -- By adding chest digital tomosynthesis in suspected cases of pulmonary lesions, patients can avoid unnecessary CT scans and imaging facilities can lower their expenses, Italian researchers have found.
Norwegian study shows DBT + mammo find more cancers
April 17, 2013 -- When conventional digital mammography is combined with digital breast tomosynthesis (DBT) for interpretation by two radiologists, cancer detection is significantly improved, especially for invasive cancers. But interpretation times nearly doubled for the combined exam.
Virtopsy: Back to the future?
April 17, 2013 -- Virtual autopsies are attracting great attention, but the concept is not new -- it's been around for decades. History columnist Dr. Adrian Thomas traces the origins of the virtopsy, and explains why they're relevant today.
New software simplifies intensity-modulated radiotherapy
April 16, 2013 -- Researchers in Germany have developed a new approach for making target treatment plans for intensity-modulated radiotherapy easier. They've developed a method to make this process easier, as described in the 21 March issue of Physics in Medicine and Biology.
Free intra-abdominal gas requires careful investigation
April 15, 2013 -- It's vital to understand how the anatomy affects the distribution of free gas within the peritoneal and extraperitoneal regions and use this to determine the most likely site of perforation, award-winning researchers from Malta and the U.K. have found.
Automated CT dose maps tailor radiation dose to patients
April 15, 2013 -- A new technique aimed at mapping CT radiation dose individually for each patient is showing just how far from reality the current standard for calculating dose can be, especially in obese patients, researchers concluded at the 2013 European Congress of Radiology.
Mammo expert Tabár releases breast health book in 3D format
April 12, 2013 -- To bridge the gap between clinicians and to educate women directly, Dr. László Tabár of Falun Central Hospital in Sweden and colleagues have released a new breast health book that includes 3D stereoscopic thick-section histology images for a better understanding of breast morphology.
CT can sub for MRI in patients with ventricular tachycardia
April 11, 2013 -- Late-enhancement CT can replace MRI for preprocedural evaluation of myocardial scar in patients with ventricular tachycardia (VT), according to a study from Italy. That's good news because CT actually needs to replace MRI for preprocedural planning in many VT patients who have contraindications to MRI.
