Dutch researchers have developed an algorithm called Sturgeon that can identify the type of brain tumor within 90 minutes. The algorithm relies on nanopore sequencing technology, enabling real-time reading of DNA sample base sequences. After training and testing, the algorithm was able to correctly identify 18 cases of brain tumor types in 40 minutes. By identifying the subtypes of brain tumors, surgeons can adjust their surgical strategies. Researchers hope to further validate the technology and compare it with standard methods.
