Biomagnetic activity in ovarian lesions

Background-Materials: This study aimed to investigate biomagnetic activity in benign and malignant ovarian diseases using the biomagnetometer SQUID. M agnetic recordings were obtained from 40 patients with palpable ovarian les ions. 19 of these were invasive carcinomas, and 21 were benign ovarian lesi ons. Methods: We used a one channel biomagnetometer SQUID (superconducting quantum inteference device), in order to measure the magnetic field from be nign and malignant ovarian diseases. Results: Interestingly, the ovarian le sion waveforms and the corresponding spectral densities were of high amplit ude in most (96%) malignant ovarian lesions, and of low amplitude in most ( 95%) benign ovarian diseases. These findings were of statistical significan ce (students t-test p < 0.005). Conclusions: It is suggested that biomagnet ic measurement of benign and malignant ovarian diseases, which is an entire ly new application of SQUID technology, is a promising procedure for assess ing ovarian tumors.
