Dedicated breast PET (dbPET) systems have improved the detection of small breast cancers but have increased false-positive diagnoses due to an increased chance of noise detection. This study examined whether reproducibility assessment using paired images helped to improve noise discrimination and diagnostic performance in dbPET. This study included 21 patients with newly diagnosed breast cancer wh...... hiện toàn bộ
Role of traditional CHO PET parameters in distinguishing IDH, TERT and MGMT alterations in primary diffuse gliomasSpringer Science and Business Media LLC - Tập 35 - Trang 493-503 - 2021

Hepatobiliary scintigraphy was performed in 23 normal subjects and 47 patients with chronic liver disease (chronic hepatitis; n=27, liver cirrhosis; n=20) to evaluate its availability as a test of liver function. After intravenous administration of Tc-99m N-pyriodxyl-5-methyl-tryptophan, the data were acquired for 60 min and the time-activity curves of ROIs (the heart and liver) were generated.

Performance measurement of PSF modeling reconstruction (True X) on Siemens Biograph TruePoint TrueV PET/CTSpringer Science and Business Media LLC - Tập 28 - Trang 340-348 - 2014
Young Sub Lee, Jin Su Kim, Kyeong Min Kim, Joo Hyun Kang, Sang Moo Lim, Hee-Joung Kim
The Siemens Biograph TruePoint TrueV (B-TPTV) positron emission tomography (PET) scanner performs 3D PET reconstruction using a system matrix with point spread function (PSF) modeling (called the True X reconstruction). PET resolution was dramatically improved with the True X method. In this study, we assessed the spatial resolution and image quality on a B-TPTV PET scanner. In addition, we assess...... hiện toàn bộ
Quantitative evaluation of salivary gland scintigraphy in Sjögren’s syndrome: comparison of diagnostic efficacy and relationship with pathological features of the salivary glandsSpringer Science and Business Media LLC - Tập 34 Số 4 - Trang 289-298 - 2020
Huang, Jingxiong, Wu, Jing, Zhao, Liang, Liu, Wen, Wei, Jihong, Hu, Zhenguo, Hao, Bing, Wu, Hua, Sun, Long, Chen, Haojun
The value of salivary gland scintigraphy (SGS) in the evaluation of Sjögren’s syndrome (SS) remains controversial. The aim of this study was to evaluate the diagnostic efficacy of quantitative SGS in patients with xerostomia and to assess the correlation between scintigraphic parameters and pathological features of salivary glands. Medical records of 165 patients with xerostomia who underwent [99m...... hiện toàn bộ
