Magnetic Resonance Spectroscopy For The Evaluation Of The Thyroid Lesions

The aim of this study was to observe the findings of magnetic resonance spectroscopy of different thyroid lesions and its correlation with histopathology.In this study, magnetic resonance spectroscopy was carried out on 30 patients having different thyroid lesions. Magnetic resonance spectroscopy (MRS) was performed on a 1.5 T super conductive system with gradient strength of 33 mTs. Fine needle aspiration cytology was done after MRS. Only 27 patients underwent surgery either because of cytopathologically proven malignancy or because of cosmetic reasons.Findings of magnetic resonance spectroscopy were compared with histopathology of thyroid specimens. It was seen that presence or absence of choline peak correlates very well with presence or absence of malignant foci within the nodule (sensitivity = 100%; specificity = 80.9%). These results indicate that magnetic resonance spectroscopy may prove to be an useful diagnostic modality for carcinoma thyroid..
