New AI system may help detect prostate cancer

IANS  |  New York 

Researchers have developed a new (AI) system to help radiologists improve their ability to diagnose

The system, called FocalNet, helps identify and predict the aggressiveness of the by evaluating (MRI) scans, and does so with nearly the same level of accuracy as experienced radiologists.

FocalNet is an artificial neural network, which uses an algorithm that comprises more than a million trainable variables, according to researchers, including Ruiming Cao from University of California,

For the study, published in the journal IEEE Transactions on Medical Imaging, the team trained the system by having it analyse scans of 417 men with Scans were fed into the system to help it learn to assess and classify in a consistent way and then compare results to the actual pathology specimen.

The team compared the system's results with readings by UCLA radiologists with more than 10 years of experience.

The findings showed the was 80.5 per cent accurate in reading MRIs, while UCLA radiologists were 83.9 per cent accurate.

Radiologists use to detect and assess the aggressiveness of malignant But it typically takes practicing on thousands of scans to learn how to accurately determine whether a is cancerous or benign and to accurately estimate the grade of cancer, the team said.

The research suggests an system could save time and potentially provide diagnostic guidance to less-experienced radiologists.
