According to mmes consulting, a team of scientists from Moscow state baumann technical university, boldenko institute of neurosurgery and prokhorov institute of basic physics, Russian academy of lasaer pointer sciences, have proposed a method to determine the boundary of brain tumors using terahertz radiation, thus significantly improving the effect of treating brain tumors.
Gliomas, the most common brain tumors, are not very sensitive to chemotherapy, and the boundaries of these tumors cannot be clearly determined by visual examination or mri, so surgical treatment is difficult.
Malignant tumors contain more water than healthy tissue. “Our diagnostic method takes advantage of this characteristic,” said kiril zaitsev, laboratory director of the prokhorov institute of basic physics at the Russian academy of sciences. “Using the new tumor border test during surgery will give us more options when determining further treatment options.” “Said sheikh isriam beshplaf, associate doctoral candidate at the burden-based institute of neurosurgery.
Researchers have tested the method with fragments of malignant brain tumors of varying degrees. During the experiment, the terahertz diagnosis results were consistent with the histological experts’ judgment, indicating that the diagnostic method was accurate and universal.
