Better together: Auto kV with iterative recon improves CCTA
Combining automatic tube potential selection and tube current modulation with iterative reconstruction delivered consistently high-quality coronary CT angiography (CCTA) images with doses that were lower by one-third, according to a new study from Korean researchers in Radiology.

Women, minorities still sparse in radiology
The percentage of women and minorities among radiologists and radiology residents has barely budged in the past eight years, making it unlikely that tomorrow's crop of medical imaging specialists will be more diverse, according to a new study in Radiology.

X-ray attenuating hand cream shields interventionalists
A new bismuth-oxide-based hand cream recently approved by the U.S. Food and Drug Administration might free interventional radiologists to focus more on their patients and worry less about radiation exposure to their own hands.

Experience matters: Senior residents log fewer trauma misses
Serious discrepancies in image interpretation are fairly rare among residents in trauma centers, particularly in the third and fourth years of training, concludes a multiyear study conducted at a tertiary care center in Virginia. Results were published online in Emergency Radiology.

Higher creatinine can occur after CT -- even without contrast
Contrast media is often blamed for what appears to be contrast-induced nephropathy (CIN) in patients getting CT scans. But Chinese researchers have found that elevated rates of serum creatinine -- a marker for CIN -- can occur after CT even in patients who never receive contrast.

USPSTF recommends CT lung cancer screening
In a landmark decision, the U.S. Preventive Services Task Force (USPSTF) on Monday issued a draft recommendation in favor of CT lung cancer screening for long-term smokers. The decision is a major step toward making the exam an accepted test with widespread application, much like breast or colorectal cancer screening.

CCTA makes the call for coronary revascularization
Addressing a question that has traditionally received little attention, researchers from South Carolina found that coronary CT angiography (CCTA) can accurately decide whether symptomatic patients at high risk of coronary artery disease actually need revascularization.

(A) F-18 AlF-NOTA-BCP137 PET/CT images before and after immunotherapy for patient 1 and patient 2. (B) F-18 AlF-NOTA-BCP137 PET/CT and MR images of patient 3 (left panels) after one cycle of immunotherapy. PET images showed higher uptake by tumor and spleen, and PET result was evaluated as positive; therefore, the patient was considered to be responder to treatment and underwent surgical resection. Representative images of hematoxylin and eosin (HE) staining and multiplex immunofluorescence of CD8 and CD137 (right panels) in HCC tumor and adjacent normal tissues of patient 3 after surgery. Nuclei were stained with 4′,6-diamidino-2-phenylindole. Primary tumors are indicated by white arrows, and increased thyroid uptake is indicated by red arrow in PET images.
