RoeKo: How to predict success of thrombectomy for stroke May 25, 2017 -- Advanced software can now be used to evaluate CT scans of stroke patients, assessing the severity of the stroke and helping to identify patients who will not benefit from thrombectomy, attendees learned at the 98th German Radiology Congress (Deutscher Röntgenkongress, RöKo 2017).
FDA finds no health effects from gadolinium retention May 25, 2017 -- There is no evidence that gadolinium remaining in the body after MRI contrast administration has any negative health effects, according to a review published on 22 May by the U.S. Food and Drug Administration (FDA). The announcement is unlikely to settle the debate over gadolinium contrast safety, however.
Ultrasound loses one of its greats in David Cosgrove May 24, 2017 -- Dr. David Cosgrove, a leading researcher and teacher from London, died on Tuesday, 16 May, at the age of 78. An enthusiast for clinical ultrasound, microbubble contrast agents, and elastography, he remained active right up to his death.
Big data comes under scrutiny at German congress May 24, 2017 -- The age of big data analytics has arrived in radiology, spawning a new word: radiomics. Computer analysis of images can provide important extra diagnostic information, but big data is not an end in itself and must always be measured against established radiological models.
Was the NHS to blame in U.K. cyberattack? May 23, 2017 -- The WannaCry ransomware cyberattack left parts of the U.K. National Health Service (NHS) at a standstill. Operations were canceled, MRI and CT units had to be shut down, and staff reverted to paper notes. Columnist Stephen Holloway asks what lessons we can learn from this attack.
MRI shows true value in invasive placenta May 22, 2017 -- Further evidence of MRI's ability to confirm suspected placental anomalies or to assist in cases of equivocal ultrasound findings has come from Saudi Arabia. A study of pregnant women found that noncontrast MRI is a sensitive diagnostic test for detecting invasive placenta.
No. 1 reason Maltese women avoid breast screening: Fear May 19, 2017 -- Fear is the top reason Maltese women avoid breast cancer screening, according to a new survey. To increase screening uptake, these women's fears must be addressed, although informing them about causes of breast cancer and its related risk factors would help too, the researchers found.
SPECT/CT advances routine oral cancer assessment May 18, 2017 -- With the addition of SPECT/CT, clinicians can find previously undetected sentinel lymph nodes in patients with early-stage oral cancer, according to a study published in the June issue of the European Journal of Nuclear Medicine and Molecular Imaging.
Gadolinium dosing calculator can guide MRI contrast use May 18, 2017 -- Given the ongoing concern over the safety of gadolinium-based contrast agents (GBCAs), researchers have developed a resource for MRI technologists and radiologists that calculates accurate and appropriate GBCA doses for patients to avoid dosing errors.
U.K. radiologists struggle to cope in wake of cyberattack May 17, 2017 -- As staff in U.K. public hospitals draw breath after the unprecedented cyberattack that strangled many departments over the weekend, radiologists have begun the dual task of catching up on vital clinical work and communication and building safeguards to prevent further breaches of internet security.
