The purpose of this study was to investigate the biomagnetic activity emitted from the prostate gland and to differentiate cancerous from benign @entity4623 with the use of biomagnetic measurement and non-linear analysis. Magnetic recordings were obtained from 47 @entity1 with @entity4623 . Histology revealed 24 @entity263 @entity1 and 23 @entity1067 ( @entity1067 ) @entity1 . The superconducting quantum interference device (SQUID) biomagnetometer was used to measure the prostate's magnetic field by placing the SQUID detector 3 mm above the symphysis pubis. The magnetic field recorded in the 2-7 Hz frequency range was of high amplitude in most malignant lesions whereas all benign cases were of low amplitude. According to our results, the sensitivity, specificity, positive predictive value and negative predictive value were 83.33%, 100%, 100% and 85.18%, respectively. By applying the Grassberger-Procaccia algorithm to the magnetoprostatogram time series in malignant and benign @entity4623 we found clear saturation in @entity4623 with m>7 whereas in the benign lesions there was not clear saturation. @entity263 emits higher biomagnetic activity than the @entity1067 . This confirms a higher angiogenic activity in @entity263 than the @entity1067 lesions. Furthermore, the saturation value in the estimation of the correlation dimension of the attractor for the @entity5 confirms the lower complexity of the system in comparison to the @entity1067 , which is characterized by higher complexity.
