title: Magnetic resonance spectroscopy as a diagnostic modality for carcinoma thyroid.
abstract: OBJECTIVE
  The aim of this study was to observe the findings of magnetic resonance spectroscopy of solitary thyroid nodules and its correlation with histopathology.
  
  
  METHODS
  In this study, magnetic resonance spectroscopy was carried out on 26 patients having solitary thyroid nodules. Magnetic resonance spectroscopy (MRS) was performed on a 1.5T super conductive system with gradient strength of 33mTs. Fine needle aspiration cytology was done after MRS. All 26 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.
  
  
  CONCLUSIONS
  It was seen that presence or absence of choline peak correlates very well with presence or absence of malignant foci with in the nodule (sensitivity=100%; specificity=88.88%). These results indicate that magnetic resonance spectroscopy may prove to be an useful diagnostic modality for carcinoma thyroid.
