title: Biomagnetic activity in ovarian lesions.
abstract: BACKGROUND-MATERIALS: This study aimed to investigate biomagnetic activity in benign and malignant ovarian diseases using the biomagnetometer SQUID. Magnetic recordings were obtained from 40 patients with palpable ovarian lesions. 19 of these were invasive carcinomas, and 21 were benign ovarian lesions.
  
  
  METHODS
  We used a one channel biomagnetometer SQUID (superconducting quantum interference device), in order to measure the magnetic field from benign and malignant ovarian diseases.
  
  
  RESULTS
  Interestingly, the ovarian lesion waveforms and the corresponding spectral densities were of high amplitude in most (96%) malignant ovarian lesions, and of low amplitude in most (95%) benign ovarian diseases. These findings were of statistical significance (students t-test p < 0.005).
  
  
  CONCLUSIONS
  It is suggested that biomagnetic measurement of benign and malignant ovarian diseases, which is an entirely new application of SQUID technology, is a promising procedure for assessing ovarian tumors.
