The Diagnostic Imaging CT modality focus page provides information, videos, podcasts, and the latest news about industry product developments, trial results, screening guidelines, and protocol guidance that touch on the use of CT across the healthcare continuum, from various cancer screenings, such as lung and colon, to cardiothoracic imaging, to appendicitis, and more.
June 7th 2023
The use of contrast-enhanced computed tomography (CECT) was associated with more than double the risk of contrast-induced acute kidney injury (CI-AKI) in patients with diabetes and an estimated glomerular filtration rate (eGFR) less than 30 mL/min/1.73 m2 in comparison to the use of non-contrast CT in this population.
Study Suggests AI Enhances Non-Contrast CT Detection of Large Vessel OcclusionJuly 29th 2022
Artificial intelligence (AI) accurately diagnosed 79 percent of proximal large vessel occlusions with an ipsiversive gaze deviation on non-contrast computed tomography (CT), according to new research findings presented recently at the Society of Neurointerventional Surgery’s (SNIS) 19th Annual Meeting in Toronto.
Iodinated Contrast Media Alternative: FDA OKs Bayer Importing Foreign-Labeled IopromideJuly 19th 2022
The Food and Drug Administration (FDA) has given the green light to Bayer to import foreign-labeled iopromide (Ultravist) to help alleviate ongoing supply challenges with iodinated contrast media in the United States.
Study Suggests Benefits of Preoperative CT for Left Atrial Appendage Occlusion ProceduresJuly 14th 2022
Emerging research shows the use of preoperative computed tomography (CT) led to improved success rates with device implantation, reduced procedure time and less device size changes in comparison to standalone transesophageal echocardiogram (TEE) for left atrial appendage occlusion (LAAO) procedures.
Study Confirms Higher Accuracy of MRI Over Emerging PSMA PET/CT for Diagnosing Prostate CancerJuly 8th 2022
Magnetic resonance imaging (MRI) had better accuracy than prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) “for detecting any grade of prostate cancer,” according to new study findings presented at the European Association of Urology Annual Congress (EAU22) in Amsterdam.
CMS Declines to Expand Coverage of Computed Tomography Colonography (CTC) for Medicare BeneficiariesJuly 7th 2022
Citing “insufficient” evidence, the Centers for Medicare and Medicaid Services (CMS) has declined a formal request by the American College of Radiology and multiple patient advocacy groups to reevaluate the lack of Medicare and Medicaid coverage of computed tomography colonography (CTC) for colorectal cancer screening.
Philips Adds Proteomic Nodule Risk Assessment to Lung Cancer Orchestrator SystemJune 30th 2022
The addition of Biodesix’s Nodify Lung nodule risk assessment tool to Philips’ lung cancer patient management system may enhance diagnostic efficiency and facilitate improved management of high-risk patients.
Colorectal Cancer Screening: Could a Lower Age Threshold Reveal Greater Screening Disparities?June 30th 2022
In a large study looking at the use of colorectal cancer screening techniques (including computed tomography (CT) colonography) between 2000 and 2018, researchers found that the 50 to 54 age group had the lowest increases in screening and a significantly higher chasm of racial and socioeconomic disparities in comparison to other age groups.
Combatting Workplace Musculoskeletal Injuries in the Radiology CommunityJune 23rd 2022
Recognizing the significant potential for workplace injuries in the radiology field, these authors discuss the proactive benefits of optimal positioning and disruptions of static posture as well as a heightened management awareness of ergonomic solutions and potential issues in maneuvering mobile imaging units.
Iodinated Contrast Media Shortage: Practical Solutions and Applications in RadiologyJune 21st 2022
As the iodinated contrast media shortage continues to have a significant adverse effect on radiology, these authors assess the pros and cons of emerging strategies and imaging alternatives.
AI Software Facilitates 22.1 Percent Reduction in Chest CT Review TimeJune 17th 2022
Noting that an AI software platform could save radiologists up to an hour a day in interpreting chest computed tomography (CT) scans, the authors of a prospective study found shorter mean interpretation times with non-contrast and contrast-enhanced CT as well as positive CT scans with and without significant new findings.
New Study Says Expansion of USPSTF Lung Cancer Screening Eligibility May be Reducing Racial DisparitiesJune 15th 2022
Emerging research shows a 14.5 percent increase among African Americans getting screened for lung cancer, which may be attributable to the United States Preventive Services Taskforce (USPSTF) lowering the minimum screening age to 50 and decreasing the smoking intensity screening threshold from 30 pack years to 20 pack years in March 2021.
Is Whole Body Imaging Warranted for Thrombocytopenia Caused by a COVID-19 Vaccine?June 14th 2022
In what may be the largest study to date to examine the use of whole-body imaging to assess multisystem thrombosis in patients with COVID-19 vaccine-induced immune thrombotic thrombocytopenia, researchers found multiple sites of thrombosis in 83 percent of patients who had additional CT, MRI and/or ultrasound imaging beyond the area of their primary complaint.
