Dynamic 4D MRI for Characterization of Parathyroid Adenomas: Multiparametric Analysis.
BACKGROUND AND PURPOSE The hypervascular nature of parathyroid adenomas can be explored by proper dynamic imaging to narrow the target lesions for surgical exploration. The purpose of this study was to establish MR perfusion characteristics of parathyroid adenomas to differentiate them from their mimics, such as subjacent thyroid tissue and cervical lymph nodes. MATERIALS AND METHODS Preopera...
متن کاملDiagnostic accuracy of 4D-CT for parathyroid adenomas and hyperplasia.
BACKGROUND AND PURPOSE 4D-CT is a novel method of multiphase CT imaging. When used to localize parathyroid adenomas and hyperplasia, this technique may allow for more robust diagnostic accuracy than traditional sonography and nuclear scintigraphy techniques. The purpose of our study is to assess the accuracy of 4D-CT for localizing pathologically proved parathyroid adenomas and hyperplasia foun...
متن کاملGenetic characterization of large parathyroid adenomas
In this study, we genetically characterized parathyroid adenomas with large glandular weights, for which independent observations suggest pronounced clinical manifestations. Large parathyroid adenomas (LPTAs) were defined as the 5% largest sporadic parathyroid adenomas identified among the 590 cases operated in our institution during 2005-2009. The LPTA group showed a higher relative number of ...
متن کاملPrevalence of the polar vessel sign in parathyroid adenomas on the arterial phase of 4D CT.
BACKGROUND AND PURPOSE The "polar vessel" sign has been previously described on sonography of parathyroid adenomas. We estimated the 4D CT prevalence of the polar vessel sign and determined features of parathyroid adenomas that are associated with this sign. MATERIALS AND METHODS Twenty-eight consecutive patients with parathyroid adenomas underwent 4D CT between 2008 and 2012 at 2 institution...
متن کاملCASE REPORT Cystic Parathyroid Adenomas on Dynamic CT
J.C. Sillery D.R. DeLone K.M. Welker SUMMARY: We have encountered 2 cases of parathyroid adenomas that are atypical because of their large size, cystic character, and faint enhancement compared with the typical solid parathyroid adenomas. Specifically, the enhancement pattern of a typical parathyroid adenoma in a multiphasic scan demonstrates rapid arterial enhancement and rapid washout on dela...
