In the newly released Lung-RADS 2022 classification system for computed tomography (CT) lung cancer screening, the American College of Radiology (ACR) has noted a variety of updates including new classification criteria for atypical pulmonary cysts and airway nodules, time intervals for nodule growth and a new stepped management approach for Lung-RADS categories 3 and 4A.

New research shows that 18F-NaF PET/CT had higher sensitivity, accuracy, and negative predictive value than 99mTc-MDP SPECT for bone metastases in patients deemed to be at high risk for prostate cancer or breast cancer.

While facilitating interdisciplinary colloaboration is a central objective with enterprise imaging platforms, this author says implementation of these platforms must ensure optimal patient privacy in sensitive cases involving abuse, assault and domestic violence.

The inclusion of digital bismuth germanate (BGO) detector material with the Omni Legend system reportedly more than doubles the sensitivity of older PET/CT devices, improves scan times, and enhances the detection of small lesions.

Out of 1,600 patients who had surgery for colorectal cancer, nearly 15 percent had pulmonary metastases within 15.4 months and higher-risk patients experienced lung metastases within three months, according to new research presented at the Scientific Forum of the American College of Surgeons Clinical Congress.

Modifications to pack-year history and smoking quit duration thresholds beyond those recommended in the 2021 United States Preventative Services Task Force (USPSTF) criteria for low-dose computed tomography lung cancer screening may more than double the number of increased lung cancer cases physicians would see with application of the 2021 USPSTF screening criteria.

In a thorough review of the literature, these authors discuss current approaches and emerging initiatives to increase the understanding of radiology reports by referring physicians as well as patients.

New research reveals that an emerging deep learning tool had comparable sensitivity and specificity to radiologist assessment of contrast-enhanced computed tomography (CT) scans for pancreatic cancer, and a 74.7 percent sensitivity rate for tumors smaller than 2 cm.

Greater imaging utilization has increased the prevalence of incidental findings or incidentalomas, but unclear clinical context and guidelines complicate management. Accordingly, these authors offer a thorough review of the literature and discuss new opportunities for improving interdisciplinary management strategies.

Comparing patients with and without comorbidities ranging from emphysema and tuberculosis to chronic obstructive pulmonary disease (COPD), researchers found that cancer detection rates and false-positive rates remained similar in lung cancer screening.

Amid emerging research showing the benefits of spectral computed tomography (CT) imaging in interventional radiology, the newly launched Phillips Spectral Angio CT Suite may provide enhanced efficiencies in care for stroke, oncology, and trauma patients.

Researchers suggest that an artificial intelligence (AI)-powered risk stratification tool for lung nodules identified on computed tomography (CT) scans may identify likely malignancies more than one year prior to definitive diagnosis.

Researchers showed the deep learning system had an area under the curve (AUC) ranging from 87 percent to 91 percent in two test sets for diagnosing solid pancreatic lesions of any size and cystic lesions 1 cm or larger on high-contrast computed tomography (CT).

Well known for her education and advocacy on the use of computed tomography (CT) colonography for colorectal cancer screening, Dr. Yee is also widely recognized for her leadership, mentoring skills and being a champion for diversity in the field of radiology.
