There was considerable variability in false-positive rates (FPRs) and nodule counts across radiologists in the National Lung Screening Trial (NLST), according to a study published online April 16 in Radiology.

The standard trauma protocol of ordering a nonfocused CT study on transferred patients who underwent a focused exam at an outside institution is unnecessary and leads to overutilization, according to an April 15 presentation at the annual meeting of the American Roentgen Ray Society in Washington, D.C. Instead, researchers recommended an imaging strategy informed by patient history and physical findings.

Radiographs have been shown to provide limited marginal value when conducted before interpretation of MRI studies of pediatric knee pain, challenging common practice and recommendations in the American College of Radiology (ACR) Appropriateness Criteria, according to a study published in the April issue of the American Journal of Roentgenology.

Bioinformatics technology has launched a revolution in DNA sequencing. Genetics experts are highlighting a range of genomics research by metagenomic analysis, genetic expressions in certain cancers and in infectious disease, according to a series of studies published in the April edition of the Journal of the American Medical Association.

Radiation dose in lumbar spine CT can be cut 41 percent by accounting for patient size, according to a study abstract in the electronic exhibit program at the American Roentgen Ray Society Annual (ARRS) annual meeting in Washington, D.C.

Now that hybrid PET/CT systems are thoroughly mainstream, standardization of practice has moved into the spotlight. A thorough F-18 FDG PET/CT oncological report should include much more than just what meets the eye, according to the authors of a comprehensive review published in the May issue of The Journal of Nuclear Medicine.

Amyloid imaging is now promising earlier Alzheimer’s disease diagnoses and potential anti-amyloid therapies in the not-too-distant future. The radiotracer C-11 Pittsburgh compound-B (C-11 PiB) has been proven effective for amyloid PET imaging and has outperformed many F-18 bound biomarkers, but the radiotracer F-18 NAV4694 is showing a binding pattern that nearly mirrors that of C-11 PiB with all the logistical perks of a fluorine-based agent, according to research being published in the June edition of The Journal of Nuclear Medicine.

To help reduce complications and improve the accuracy and safety of interventional procedures, Toshiba America Medical Systems, Inc. extends AplioTM 500’s Smart Fusion ultrasound technology to MR.
