Bilateral breast ultrasound of limited use in recalled patients October 17, 2012 -- Bilateral breast ultrasound offers little or only marginal benefit in routine breast cancer screening for recalled patients, German researchers have found. In their study published in European Radiology, ultrasound detected unexpected breast cancer in dense breasts, but ultrasound-only cancer detection had a low positive predictive value.
Russian military study illuminates ankle inversion injuries October 17, 2012 -- The most common pathologic changes occurring in acute ankle inversion trauma are tears to the anterior talofibular and calcaneofibular ligaments, followed by injuries to the sinus tarsi structures and tears to the peroneus longus and brevis tendons, according to a study conducted at a top Russian military hospital.
JFR: French congress puts stress on intervention and ethics October 16, 2012 -- Interventional radiology's status has visibly moved up the agenda at the 2012 French national radiology congress, the JFR, which starts in Paris on Friday, not only because of the program's vast array of sessions dedicated to it but also because of the subspecialty's new inclusion in the official title.
ESGAR publishes consensus statement on CT colonography October 15, 2012 -- The European Society of Gastrointestinal and Abdominal Radiology (ESGAR) has published its first update on CT colonography (CTC) guidelines since 2007. Its working group on CTC has endorsed 86 statements, reaching near-complete agreement on 71 of the 86 items relating to critical practice areas affecting CTC.
Noncontrast CT may underestimate lung nodule volume October 15, 2012 -- Low-dose unenhanced CT scans may underestimate the volume of smaller lung nodules compared with standard-dose contrast CT studies, creating potential problems when tracking nodules over time, wrote researchers in the October issue of the American Journal of Roentgenology.
MIR: Technology proves double-edged sword for workload October 12, 2012 -- Efficient use of teleradiology, along with efforts to control imaging demand, will play a central role in reducing future radiology workload, according to a senior Turkish radiologist who is speaking at this week's Management in Radiology (MIR) scientific meeting in Milan.
Use CT as frontline tool in acute stroke, experts urge October 11, 2012 -- Acute stroke patients should be evaluated by noncontrast CT followed by perfusion CT, while MRI should be reserved for more chronic cases of brain ischemia or control examinations in stroke patients. That's the recommendation of an experienced group of specialists from the Czech Republic.
Swiss give new advice on MRI technique for female pelvis October 10, 2012 -- The less-motion-sensitive T2-weighted BLADE technique should not replace conventional turbo spin echo when imaging a woman's pelvis because, despite its appeal, overall contrast suffers, according to Swiss researchers.
Imaging can unlock secrets of archeological wet wood October 10, 2012 -- Austrian researchers are convinced that MRI has much to offer when it comes to dendrochronology, the scientific method of dating based on the analysis of patterns of tree rings. In archeology, the technique is used extensively to date old buildings and objects.
DWI-MRI monitors response to colorectal cancer treatment October 10, 2012 -- The ability of diffusion-weighted imaging (DWI) to create good reproducibility, correlate with histopathology, and enhance sensitivity to assess treatment results may make MRI an "excellent tool" to monitor response in metastatic colorectal cancer patients, according to a new Dutch study.
