    Article Snippet: CT-based attenuationcorrected SPECT and quantitative SPECT were reconstructed on 256 × 256 matrices using Flash 3D-ordered subset expectation maximization and an ordered subset conjugate gradient maximization (xSPECT Quant, Siemens Medical Solutions, IL) algorithms (eight subsets and four iterations; Gaussian filter of 8.0), respectively.

    Article Title: Evaluation of standardized uptake value on 131 I-6β-iodomethyl-19-norcholesterol scintigraphy for diagnosis of primary aldosteronism and correspondence with adrenal venous sampling.
    Article Snippet: Purpose Adrenal venous sampling (AVS) is a reliable method for lateralization of adrenal hormone secretion, which is important for discriminating between aldosterone-producing adenoma and bilateral adrenal hyperplasia, both of which cause primary aldosteronism (PA).. The aim of this study was to evaluate the diagnostic accuracy of the maximum and mean standardized uptake values (SUVmax and SUVmean, respectively) of 131I-6β-iodomethyl-19-norcholesterol (NP-59) singlephoton emission computed tomography (SPECT) for PA and its correspondence with AVS.. Methods Adrenal NP-59 scintigraphy was performed in 14 patients with suspected PA, and AVS was also performed in 7 of them.
