Dedicated breast MRI reins in false positives
October 1, 2012 -- Use of a specialized breast MRI scanner led to a sharp decline in false positives compared to breast imaging on whole-body MRI scanners in a study published in the October issue of Radiology. The results address what has historically been a weak point for breast MRI: its specificity.
Noncontrast CT may underestimate lung nodule volume
October 1, 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.
Risk markers found for erectile dysfunction after RT
October 1, 2012 -- Genetic markers associated with the development of erectile dysfunction in prostate cancer patients following radiation therapy (RT) have been identified, according to a study published online on September 27 in the International Journal of Radiation Oncology, Biology, Physics.
Patients want to hear exam results from radiologists
September 28, 2012 -- Patients prefer hearing exam results from both their general physician and their interpreting radiologist, according to a new study published in the October issue of the American Journal of Roentgenology. This is good news for a specialty challenged to come out of the reading room and into more daily patient contact.
NLST stands alone in finding lung screening mortality benefit
September 28, 2012 -- A new meta-analysis of lung cancer screening studies shows that only one of three randomized trials that looked at mortality found a benefit from screening. Still, the comparison is questionable inasmuch as the two studies analyzed along with the National Lung Screening Trial (NLST) may be too small with too little follow-up.
Statewide imaging repository takes off in Australia
September 28, 2012 -- Although technically and financially challenging, making a patient's radiology images and records accessible to any physician who needs them is intrinsic to the concept of digital radiology. In Australia, the state of New South Wales is making this happen.
Subspecialty second reads improve pediatric patient care
September 27, 2012 -- In research that may support the case for more subspecialization in radiology, a Wisconsin team found that the rate of disagreement between interpretations of pediatric imaging studies by generalist community radiologists and specialty radiologists at tertiary care pediatric hospitals can be as high as 42%.
Iterative dose reduction with 3D enhances CT image quality
September 27, 2012 -- The use of an advanced iterative reconstruction technique with 3D processing can improve image quality and interreader agreement in reduced- and low-dose CT scans for patients with pulmonary diseases, Japanese researchers have found.
Nuclear medicine pioneer Dr. Henry Wagner passes away
September 26, 2012 -- Dr. Henry Wagner Jr., a pioneer in the field of nuclear medicine and past president of the Society of Nuclear Medicine and Molecular Imaging, died on September 25 at the age of 85. Wagner is credited as being one of the founders of nuclear medicine as a scientific and medical specialty.
Radiology: Time to mothball 'low-dose' terminology
September 26, 2012 -- The terms "low dose" and "standard dose" are meaningless, so if the paper you're submitting to Radiology includes them, expect to get it back, say the editors of the specialty's flagship journal.
