PET/MRI offers 'powerful' option for unknown primary cancer
September 20, 2016 -- PET/MRI is just as proficient as PET/CT in detecting primary cancer and metastases from an unknown primary tumor, making PET/MRI a "powerful alternative" with significantly less exposure of patients to ionizing radiation, according to a German study in the European Journal of Radiology.
Clinical progress in focused ultrasound
September 20, 2016 -- Focused ultrasound is a developing noninvasive treatment technique that delivers ultrasonic energy to targets deep within tissue. During therapy, individual ultrasound beams pass harmlessly through adjacent tissue then converge to a focal point at the target, for a profound therapeutic effect.
CMR, scintigraphy do more to prevent unnecessary angiography
September 19, 2016 -- When physicians craft treatment plans for patients with suspected angina based on cardiovascular MRI (CMR) and SPECT myocardial perfusion imaging results, the chance of unnecessary angiographies is much less than if care is based on tried-and-tested guidelines, according to U.K. researchers.
Action on CT dose brings results in Middle East
September 19, 2016 -- A multicenter study conducted in Saudi Arabia and the United Arab Emirates has underlined the value of implementing dose-reduction techniques for coronary CT angiography and coronary calcium score examinations.
Migrants: How to determine age on pelvic x-rays
September 16, 2016 -- In an attempt to assist decision-makers in the migrant crisis, Turkish researchers have redoubled their efforts to identify an accurate way of evaluating bone age using pelvic radiographs in young adults.
Ultrasound monitors therapeutic microbubbles
September 15, 2016 -- In new work, U.K researchers have estimated microbubble velocities during therapeutic ultrasound exposure by measuring the Doppler shift of ultrasound emitted by the microbubbles as they underwent cavitation. The measurements are implementable in real-time with existing detectors.
U.K. radiologist shortage worsens
September 14, 2016 -- The shortage of radiologists in the U.K. is getting worse, according to a census released by the Royal College of Radiologists on 10 September. Demand for imaging services increases, but the supply of radiologists does not. A key finding is that 99% of U.K. radiology departments could not meet scan and x-ray reporting demands.
fMRI finds dogs get style and substance of words
September 14, 2016 -- Add a mark to the win column for dog lovers: A recent Hungarian study using functional MRI (fMRI) found that man's best friend responds to both your words and how you say them. The results also help clarify how our ability to communicate may have evolved.
Structured reporting finds little traction in Italy
September 13, 2016 -- Although many radiologists in Italy are open to adopting structured reporting, technical and professional concerns have largely limited the technology's use in daily practice so far, Italian researchers reported recently in an article published online in European Radiology.
3D luminescence imaging shows subtle bone damage
September 13, 2016 -- Researchers at Trinity College in Dublin have devised an experimental 3D bone scanning technique that may improve the diagnosis of bone injuries without the use of ionizing radiation, according to a new study published in Chemical Communications.
