Scientists at Purdue University have devised a simulator that can give an idea about the effect of strong magnetic fields of the power of about 7 Tesla, on human breast tissue of varying densities. The regular MRI machines in hospitals generate magnetic fields of about 3 Tesla as high resonance magnetic fields could lead to excessive heating and permanent hampering of tissues. However, the exact effect of such high power has been a mystery.
The study was published in the journal, Magnetic Resonance in Medicine.
20 varying breast tissues were simulated and the quantity of heat produced in the scanned tissue was assessed. The heat increased with the density of the tissue, as a greater amount of electromagnetic waves were absorbed by the tissue.
This research could enhance the diagnostic ability of MRI machines which could then be used in the majority of the hospitals. It would not lead to a conclusive result but will surely present an open tool for further research in this field. Additionally, MRI machines may be used for non-invasive therapeutic purposes in the future if high-power concentrated and regulated electromagnetic waves could destroy deep tumor cells.
