Chest pain patients do well after ultralow-dose SPECT
April 10, 2015 -- Patients with chest pain who underwent SPECT myocardial perfusion imaging with an ultralow-radiation-dose gamma camera had no major cardiac events a year later. The research, published in the April issue of the Journal of Nuclear Medicine, indicates that MPI radiation dose can be slashed without adverse clinical impact.
Study finds wild price variations for head CT scans
April 9, 2015 -- The price of a noncontrast head CT scan can vary more than fivefold in academic hospitals and more than tenfold in private practices across the U.S., according to a new study published online in the Journal of the American College of Radiology.
Study advises MRI screening for high-risk pancreatic cancer patients
April 8, 2015 -- Swedish researchers believe that MRI could be the best imaging modality to screen people at high risk of pancreatic cancer, according to an April 8 study in JAMA Surgery. In a small study, they showed how using MRI to screen high-risk individuals found pancreatic lesions in 40% of patients.
3T MRI shows how meniscus tears heal, predicts outcomes
April 8, 2015 -- MRI at 3 tesla can help forecast the healing potential of a meniscus tear based, in part, on decreased meniscus extrusion, according to a study presented March 28 at a meeting of the American Orthopaedic Society for Sports Medicine.
Mammo false positives, overdiagnosis cost U.S. $4B per year
April 7, 2015 -- False positives and overdiagnosis related to mammography screening cost the U.S. $4 billion per year, a figure that's much higher than previous estimates, according to a study published in Health Affairs. But the study's findings are based on previous research that has already been criticized by advocates of screening.
FDDNP-PET gives insight into brain trauma of NFL players
April 7, 2015 -- Brain scans with the PET radiopharmaceutical FDDNP of former National Football League (NFL) players who experienced multiple concussions show patterns that are similar to patients who experienced chronic traumatic encephalopathy, according to an April 6 study in the Proceedings of the National Academy of Sciences.
Should radiology residency be reduced to 3 years?
April 7, 2015 -- Should the current radiologist training schedule be changed from four years of residency to three and turn the fourth year of education into a fellowship? Such a structure might better reflect recent changes in radiology education and employment, according to an opinion published online in the Journal of the American College of Radiology.
Coregistered 3D US plus angio boosts aneurysm surgery
April 6, 2015 -- Combining rotational digital subtraction angiography with 3D ultrasound creates a powerful pair for guiding aneurysm surgery when images are dynamically coregistered during procedures, according to a new study by German researchers and published in PLOS One.
NCI: Cancer incidence, mortality continue to fall in U.S.
April 6, 2015 -- Rates of cancer incidence and mortality continue to fall in the U.S., according to a new report by the U.S. National Cancer Institute (NCI). Deaths from cancer dropped 1.8% annually in men and 1.4% annually in women from 2002 to 2011, the report disclosed.
Not all clinical decision support software is created equal
April 3, 2015 -- A new study has found fundamental differences in the effectiveness of clinical decision support based on the type of software that's used. In a study published in the Journal of the American College of Radiology, researchers found that radiologists can become frustrated if the software is not easy to use.
Practice of Ultrasound: Part 22 -- Quantum ultrasonics
April 3, 2015 -- In the next installment of his series on the practice of ultrasound, Dr. Jason Birnholz delves into the quantum energy foundations of ultrasound, providing a fundamental link to all other diagnostic imaging techniques.
Study: It's tough complying with Calif. dose reporting law
April 2, 2015 -- Compliance with California's radiation dose reporting law is difficult because dose reporting processes that rely on manual data entry are unreliable -- at least in the experience of one large institution -- according to a new study in the American Journal of Roentgenology.
Breast imaging providers must lead density education
April 2, 2015 -- Radiologists are uniquely suited to discuss breast density with patients and should take the lead in patient information efforts, according to Dr. Amy Thurmond of Womens Imaging & Intervention in Oregon. In this column, Thurmond discusses how her practice talks about density with its patients.
Long-term study confirms safety of gadolinium MRI contrast agent
April 1, 2015 -- Amid persistent concerns over the safety of gadolinium MRI contrast agents, a new study published in the April issue of the American Journal of Roentgenology reinforces the "relatively robust safety profile" of at least one MRI agent. Adverse reactions were tracked over nearly eight years and found to be "infinitesimally small."
Ultrasound should be 1st choice for female pelvic imaging
March 31, 2015 -- Female pelvic pain is often evaluated with MRI and CT, adding cost and -- in the case of CT -- radiation exposure for patients. Ultrasound is the better initial choice, according to an article published online Tuesday in the American Journal of Obstetrics & Gynecology.
