Volumetry software affects CT lung screening recall rates
Using different types of volumetry software to measure nodules on CT lung cancer screening exams can drastically alter the recall rate for follow-up exams, underscoring the need to validate the software to ensure effective screening, according to an article recently published online in the European Journal of Radiology.

ISCT: 5 clinical benefits of photon-counting CT
SAN DIEGO - Photon-counting CT scanners might not yet be available for everyday clinical use, but early studies have shown that the technology can offer clear benefits over conventional CT, many of which Cynthia McCollough, PhD, detailed in the opening session of the 2019 International Society for Computed Tomography (ISCT) symposium.

3D VR models improve kidney-sparing surgery outcomes
Examining 3D virtual reality (VR) models during presurgical planning for robotic-assisted partial nephrectomy led to reductions in operating time, blood loss, and hospital length of stay compared with planning based on MRI and CT scans alone in a new study, published online September 18 in JAMA Network Open.

Clinical study validates ultrahigh-resolution chest CT
An ultrahigh-resolution CT scanner substantially improved the quality of imaging data acquired from patients with various chest diseases, compared with a standard CT scanner, in a new study, recently published online in the Journal of Computer Assisted Tomography. The advanced CT technology may enhance diagnostic imaging and disease characterization.

Risk model improves accuracy of CT lung cancer screening
Using a risk-prediction model to determine eligibility for CT lung screening is more effective for detecting cancers than current guidelines from the U.S. Preventive Services Task Force, according to new results from the International Lung Screen Trial presented at the recent World Conference on Lung Cancer in Barcelona, Spain.

New 3D bioprinting method produces functional organ tissue
Researchers from Harvard University have developed a new 3D bioprinting method that uses a combination of stem cells and 3D CT data to produce functional, patient-specific organ tissue. The resulting 3D-bioprinted models are poised to facilitate organ repair and restoration, according to an article recently published online in Science Advances.

Stroke care looks skyward with new mobile CT program
The notion that stroke care could one day take to the skies seems more likely now than ever. Researchers from Australia have launched a new research program tasked with developing portable brain CT scanners that can be installed onboard aircraft to give rural areas access to faster stroke intervention.

Blood biomarkers bolster CT lung cancer screening
Adding a blood test to CT lung cancer screening improved the early detection of lung cancer by 36% in an ongoing study and may help lower mortality rates in high-risk smokers, compared with standard clinical care, according to a September 9 presentation at the World Conference on Lung Cancer in Barcelona, Spain.

Virtual reality relieves kids' anxiety over chest x-ray
Educating pediatric patients about their upcoming chest x-ray exam with virtual reality technology helped reduce preprocedural anxiety, and, in turn, the need for repeat exams and parental presence in the imaging suite in a new study, published online September 9 in JAMA Pediatrics.

3D MRI technique helps plan treatment for pediatric heart conditions
Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.
