CT lung screening rates show gradual upward trend
Participation in CT lung cancer screening programs among eligible individuals in the U.S. has been making modest gains over the past several years. The U.S. Centers for Disease Control and Prevention released on February 28 new survey findings with statewide rates as high as 16%.

CT CAC predicts risk of death in smokers
The presence of coronary artery calcium (CAC) on CT scans was associated with an increased risk of death from cardiovascular diseases, cancer, and all causes combined -- including for a subset of smokers eligible for CT lung cancer screening -- in a study published in the February issue of Atherosclerosis.

What do radiologists need to know about the coronavirus?
To help radiologists stay up to date on the ever-evolving coronavirus epidemic, an expert panel gave the lowdown on the current understanding of the coronavirus disease and highlighted the points most pertinent to radiologists in an article published online on February 27 in Radiology.

CT again tops DNA tests for early coronavirus detection
In a study covering more than 1,000 confirmed cases of the novel coronavirus disease, chest CT proved to be more accurate than the standard method of DNA testing for early diagnosis of the disease in high-risk individuals. The findings were published online February 26 in Radiology.

3D light scanner supplements CT for bedside procedures
Researchers from Tennessee have developed a navigation technique that employs a 3D light scanner and 3D printing technology to improve the accuracy and workflow of minimally invasive procedures reliant on CT data. They describe their technique in an article recently published in World Neurosurgery.

How can radiology help limit COVID-19 transmission?
The critical role of CT in diagnosing the novel coronavirus disease (COVID-19) has placed radiology at the frontline of disease management. Researchers discuss preemptive measures radiology departments can take to limit virus transmission in a February 19 article published in the Journal of the American College of Radiology.

CT proves vital for early diagnosis of COVID-19
Chest CT demonstrated better sensitivity than DNA testing at detecting coronavirus disease (COVID-19) in high-risk individuals upon initial presentation of symptoms in a new study, published online February 19 in Radiology. The findings affirm the vital role of CT in the early diagnosis of the condition.

Prehydration not needed before contrast CT of kidneys
Prehydrating patients who have chronic kidney disease before they undergo a contrast-enhanced CT exam has been the standard of care for years. But new research suggests that the practice results in unnecessary costs with few patient benefits. The findings were published online on February 17 in JAMA Internal Medicine.

Can ultrasound, 3D printing deepen maternal-fetal bonds?
When a pregnant woman sees her fetus on imaging scans, it can help strengthen the bond she feels with her unborn child, say researchers. They demonstrate how 3D-printed models based on ultrasound scans confirmed this concept in a study published online on February 8 in the Journal of Obstetric, Gynecologic, and Neonatal Nursing.

Subgroup analysis based on lesion size on PCCT images. The red outlined areas highlight the magnified images of lesions. (A-C) PCCT images in a 62-year-old woman with a body mass index (BMI) of 23.6, calculated as weight in kilograms divided by height in meters squared, who was diagnosed with adenocarcinoma. A lesion with a long diameter of 25 mm was identified in the right lower lobe on axial images acquired during the venous phase. For lesions less than or equal to 30 mm, decreasing section thickness improved boundary sharpness and contrast between the necrotic area and enhanced tissue, with optimal visualization at 0.4 mm. (D-F) PCCT images in a 66-year-old man with a BMI of 24.2 who was diagnosed with adenocarcinoma, revealing a lesion with a long diameter of 52 mm in the right lower lobe. For lesions greater than 30 mm, a section thickness of 1 mm demonstrated better contrast and clarity at the boundary of the necrotic area compared with 0.4 mm. This observation supported the selection of an appropriate section thickness for accurate quantification of necrotic regions within the lesion.
