AI/CT Combination for Assessing Pulmonary Embolism Severity Gets FDA Nod

February 23, 2023

Facilitating expedited assessment of pulmonary embolism severity, the emerging artificial intelligence (AI) tool Rapid RV/LV reportedly calculates the right ventricle/left ventricle (RV/LV) ratio within minutes of a computed tomography pulmonary angiogram (CTPA).

Can a New AI Tool Improve Detection of Incidental Pulmonary Embolism on CT?

February 22, 2023

Noting that only 25 percent of incidental emboli are identified in reporting of initial computed tomography (CT) exams, Avicenna.AI said the artificial intelligence (AI)-enabled CINA-iPE is geared toward detecting incidental pulmonary embolism (PE) on chest CT scans.

Is Follow-Up Pelvic CT Coverage Necessary for Patients Treated for Hepatocellular Carcinoma?

February 22, 2023

Noting that pelvic coverage can increase radiation dosing for liver computed tomography (CT) by 29 to 39 percent, researchers found low three-year cumulative rates of incidental pelvic tumors and isolated pelvic metastasis in follow-up liver CT imaging of over 1,100 people treated for hepatocellular carcinoma.
