The LUCA device shows high accuracy in thyroid cancer screening
Thyroid nodules are a common pathology having a prevalence of 19-76% when screened with ultrasound, with higher frequencies in women. Current medical methods used to assess the malignancy of a nodule consist in performing an ultrasound, followed by a Doppler ultrasound, and then a biopsy. However, unfortunately, these methods present both low specificity and low sensitivity. This insufficient effectiveness in accurately being able to diagnose thyroid tumors leads to many unclear or unnoticed cases as well as many others that undergo unnecessary surgeries (false positives) and increase the cost of medical healthcare, not to mention the reduction of quality of life of patients.

Scientists’ algorithm will diagnose thyroid tumors faster Researchers from 10 leading centers in Russia, including TSU, have developed a new approach to diagnosing thyroid tumors, based on a blood test. The main diagnostic tools are spectroscopy and machine learning. The role of the TSU scientists was to create methods of analysis using artificial intelligence. The results are presented in the highly ranked journal Biomedical Optics Express (Q1). The methods used today to diagnose thyroid tumors are either complicated or not accurate enough,- explains Yuri Kistenev, head of the TSU Laboratory of Biophotonics and executive director of the TSU Institute of Biomedicine. -Our approach involves the analysis of molecular markers of blood by terahertz spectroscopy and machine learning.
