Magnetic induction useful in prostate cancer diagnosis
July 10th, 2009 Posted in prostate cancer diagnosisThe results of a preliminary study at Istanbul University, Turkey, indicate that a noninvasive magnetic induction technique for assessing the resonance of tissues may be useful as a screening tool for prostate cancer.
Magnetic fields associated with bioelectric interactions may be detected non-invasively by coupling the oscillations of a probe with those from the biological tissues to produce a phenomenon called nonlinear resonance interaction.
Researchers used the Tissue Resonance Interaction Method (TRIMprob) to assess 148 men, and concluded that TRIMprob had a sensitivity, specificity, positive predictive value, and negative predictive value for the diagnosis of prostate cancer. Furthermore, TRIMprob had a greater area under the receiver operating characteristics curve for predicting prostate cancer than total PSA, free/total PSA ratio, and PSA density
