Proton magnetic resonance and @entity1 thyroid neoplasia. II: Potential avoidance of surgery for XXXX .

@entity5 @entity1 @entity652 @entity259
@entity259 is rare, but many thyroidectomies continue to be performed simply to exclude a diagnosis of @entity5 . The purpose of this study was to determine the potential financial savings associated with the use of proton magnetic resonance analysis of @entity5 . Proton magnetic resonance spectroscopy was performed on tissue obtained at the time of surgery from 98 consecutive solitary or dominant thyroid nodules. Fine-needle biopsies were also performed on operative specimens, and the tissues assessed by proton magnetic resonance; these spectra were then compared with those obtained from tissue specimens. An estimate of potential savings was obtained by comparing the magnetic resonance data with the indications for surgery and pathology on all @entity1 having thyroidectomy over a 10-year period. Proton magnetic resonance spectroscopy was able to distinguish between normal thyroid tissue and invasive @entity259 with 100% specificity. @entity652 fall into two groups: 44% having a spectral pattern comparable with normal thyroid, and the remaining 56% demonstrating an altered spectral pattern more comparable to the malignant magnetic resonance profile. Proton magnetic resonance spectroscopy on fine-needle biopsy specimens produced spectra similar to those from tissues from the same @entity1 . From a fine-needle biopsy specimen, proton magnetic resonance spectroscopy can identify a group of @entity652 with spectral profiles akin to those of normal thyroid cells, thus avoiding the need for unnecessary surgical excision. The potential savings in one surgical unit alone were over  1 million in 10 years.
