Of the 429 chest X-rays that were classified as normal, 120, or 28%, were also classified by the AI tool as normal. These X-rays, or 7.8 % of all the X-rays, could be potentially safely automated ...

Two freely available chest X-ray datasets were used to test and train the AI model. The datasets comprised three categories of chest X-ray images: normal, coronavirus-positive, and viral pneumonia.

Generally, a pulmonary nodule must grow to at least 1 cm in diameter before it can be seen on a chest X-ray. An SPN is surrounded by normal lung tissue and is not associated with any other ...

A chest X-ray or CT scan often detects lung nodules—small growths in the lungs—incidentally. While most lung nodules are benign, here’s to finding out if they are cancerous.

Early research suggests a promising use of artificial intelligence to predict the 10-year risk of death from a heart attack or stroke from a single chest X-ray.

A chest X-ray does not directly show pulmonary embolism. However, it may help a doctor rule out health problems that cause similar symptoms, such as pneumonia and some heart conditions.
