Chest CT Study Shows Higher Emphysema Risk from Combination of Marijuana and Cigarette Smoking
November 28th 2023People who smoke marijuana and cigarettes have 12 times the risk for centrilobular emphysema than non-smokers, according to new computed tomography (CT) research presented at the annual Radiological Society of North America (RSNA) conference.
Study Suggests CT-Guided Injections May Restore Sense of Smell in Patients with Long COVID
November 20th 2023Utilizing computed tomography (CT) guidance, researchers have found that performing a minimally invasive anesthetic injection into the stellate ganglia may help address parosmia due to COVID-19, according to study results that will be presented at the annual Radiological Society of North America (RSNA) conference next week.
Is Photon Counting CT a Better Option than Dual-Energy CT for Pulmonary Angiography?
November 17th 2023Performing computed tomography pulmonary angiography (CTPA) with a high-pitch photon counting detector (PCD) offers enhanced signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) at a reduced radiation dose in comparison to employing an energy-integrating detector (EID), according to new research.
New Dual-Source CT Device May be Cost-Effective Alternative for Smaller Facilities
November 16th 2023Offering a combination of simplified and personalized scanning for patients at significantly lower lifecycle costs than other dual-source CT systems, the Somatom Pro.Pulse may be a viable option for smaller rural facilities and outpatient imaging centers.
Is Surveillance Imaging Necessary After Primary Radiation for Head and Neck Cancer?
November 13th 2023For patients who had a complete metabolic response to radiation treatment for head and neck cancer, the authors of a recent study found that surveillance imaging with PET/CT, MRI or CT did not improve outcomes in comparison to expectant management.
Study Says MRI Offers Most Cost-Effective Imaging for Dizziness Presentations in the ER
November 10th 2023Noting that initial imaging sensitivity is a key factor in cost-effectiveness for patients who do not require acute treatment for dizziness, researchers found that specialized MRI (including multiplanar high-resolution DWI) provided the most benefit in a comparative trial of neuroimaging modalities.
CT News: American Cancer Society Issues Updated Lung Cancer Screening Recommendations
November 2nd 2023In a newly updated guidance, the American Cancer Society recommends the expansion of annual lung cancer screening with low-dose computed tomography (LDCT) for current or previous smokers 50 to 80 years of age who have a 20-pack-year or greater history of smoking.

Current Concepts with Advances in Photon-Counting Computed Tomography
October 26th 2023Photon-counting computed tomography (PCCT) offers a number of salient advantages over conventional CT, including improved image resolution and contrast-to-noise ratio, enhanced denoising capability and inherent spectral sensitivity.
Can Deep Learning Bolster CT Detection and Classification of Usual Interstitial Pneumonia?
October 18th 2023In a multicenter cohort of patients with interstitial lung disease (ILD), a deep learning classification tool demonstrated an 81 percent sensitivity rate and a 77 percent specificity rate for predicting usual interstitial pneumonia on computed tomography (CT) scans.
Study Shows Mixed Results with AI Software for PE Detection on CTPA Scans
October 5th 2023While the artificial intelligence (AI) triage system significantly reduced wait times for computed tomography pulmonary angiography (CTPA) results that were positive for pulmonary embolism (PE), researchers found no significant differences in the use of adjunctive AI with respect to accuracy rates and specificity rates.
