Purpose To evaluate the diagnostic performance of parathyroid 4D CT and technetium 99m-sestamibi (hereafter, referred to as sestamibi) SPECT/CT in preoperative localization in patients with primary hyperparathyroidism. The diagnostic performance of 4D CT, sestamibi SPECT/CT, combined sensitive reading, and combined specific reading to detect a parathyroid adenoma was calculated by using a binary classifier system (healthy tissue vs parathyroid adenoma or hyperplasia) and nonparametric receiver operating characteristic curve. 2014-11-27 99mTc-sestamibi/123I subtraction SPECT/CT in parathyroid scintigraphy (PS).

The difference between SPECT Scanning for parathyroids and and routine SPECT (Single Proton Emission Computerized Tomography) scanning is a new technique whereby images can be obtained of diseased glands which have absorbed a radioactive marker.

Objective: To evaluate 4-dimensional (4D) computed tomography (CT) for the localization of parathyroid adenomas previously considered nonlocalizing on ultrasound and single-photon emission CT with CT scanning (SPECT-CT). To measure radiation exposure associated with 4D-CT and compared it with SPECT-CT. For example, SPECT/CT may be used in sestamibi parathyroid scan applications, where the technique is useful in locating ectopic parathyroid adenomas which may not be in their usual locations in the thyroid gland.

Early SPECT/CT in combination with any modality for delayed imaging emerged as the best overall protocol, with an accuracy of approximately 86%. The increased anatomical detail offered by SPECT/CT is demonstrated in 1 study of 23 patients that noted the mean distance from predicted to actual adenoma location at surgery was 16.3 ± 2.7 mm SPECT and PET in Benign Thyroid and Parathyroid Disease Ujwal N. Bhure Daniela B. Husarik The role of integrated single-photon computed tomography (SPECT) and integrated positron emission tomography and computed tomography (PET-CT) in imaging thyroid and parathyroid disease is still largely undefined. BACKGROUND AND PURPOSE: Minimally invasive parathyroid surgery relies critically on image guidance, but data comparing the efficacy of various imaging modalities are scarce. Our aim was to perform a blinded comparison of the localizing capability of technetium Tc99m sestamibi SPECT, multiphase multidetector 4D CT, and the combination of these 2 modalities (technetium Tc99m sestamibi SPECT Parathyroid scintigraphy was performed according to our standard protocol as follows: Pinhole images were performed on Philips Skylight γ-camera (Philips Healthcare, Eindhoven, The Netherlands) and SPECT/CT was performed on a Philips Precedence SPECT/CT scanner or a Siemens Symbia Intevo SPECT/CT scanner (Siemens Healthcare, Erlangen, Germany). Parathyroid scintigraphy, particularly when combined with CT (e.g.

SPECT/CT's Advantage for Preoperative Localization of Small

Se hela listan på jaocr.org As with FDG-PET/CT in patients with other malignant disease, SPECT/CT has drastically reduced the difficulty of fusing anatomical and physiological data sets obtained at different time points, improving the accuracy of tracer localization in many patients with thyroid and parathyroid neoplastic disease. Objective: To evaluate 4-dimensional (4D) computed tomography (CT) for the localization of parathyroid adenomas previously considered nonlocalizing on ultrasound and single-photon emission CT with CT scanning (SPECT-CT).
