Role of traditional CHO PET parameters in distinguishing IDH, TERT and MGMT alterations in primary diffuse gliomas
Springer Science and Business Media LLC - Tập 35 - Trang 493-503 - 2021
Ziren Kong, Yucheng Zhang, Delin Liu, Penghao Liu, Yixin Shi, Yaning Wang, Dachun Zhao, Xin Cheng, Yu Wang, Wenbin Ma
Isocitrate dehydrogenase (IDH) mutation, telomerase reverse transcriptase (TERT) promoter mutation and O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status are diagnostic, prognostic, predictive and therapeutic biomarkers for primary diffuse gliomas, and this study aimed to explore the relationship between choline (CHO) positron emission tomography (PET) parameters and these m...... hiện toàn bộ
Reproducibility assessment of uptake on dedicated breast PET for noise discrimination
Springer Science and Business Media LLC - Tập 37 - Trang 121-130 - 2022
Shunsuke Yuge, Kanae K. Miyake, Takayoshi Ishimori, Masako Kataoka, Yoshiaki Matsumoto, Koji Fujimoto, Tomoharu Sugie, Masakazu Toi, Yuji Nakamoto
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
Assessment of hepatic excretory function in chronic liver disease by hepatobiliary scintigraphy
Springer Science and Business Media LLC - Tập 3 - Trang 139-142 - 1989
Hisao Itoh, Norio Takahashi, Reiko Shimono, Takafumi Sugawara, Masashi Kawamura, Takaharu Tsuda, Masaaki Kataoka, Atsushi Iio, Ken Hamamoto, Kanji Ohshima, Koichi Akamatsu
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.

Fluorine- 18-fluorodeoxyglucose positron emission tomography for assessment of patients with unresectable recurrent or metastatic lung cancers after CT-guided radiofrequency ablation: Preliminary results
Springer Science and Business Media LLC - Tập 20 - Trang 115-121 - 2006
Tomohisa Okuma, Terue Okamura, Toshiyuki Matsuoka, Akira Yamamoto, Yoshimasa Oyama, Masami Toyoshima, Koichi Koyama, Kiyotoshi Inoue, Kenji Nakamura, Yuichi Inoue
We compared the diagnostic value of fluorine-18-fiuorodeoxyglucose positron emission tomography (FDG-PET) with that of computed tomography (CT) following radiofrequency ablation (RFA) of inoperable recurrent or metastatic cancers in the lung. Twelve patients (9 males and 3 females; 5 had recurrent lung cancer and the other 7 had metastatic nodules from a variety of primary cancers) were treated by...... 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 glands
Springer 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

Abstract Purpose To evaluate fluorine-18 fluorocholine (FCH) PET/CT for the detection of recurrent prostate cancer in relation to prostate-specific antigen (PSA) level. Methods FCH PET/CT ...... hiện toàn bộ
Comparison of gallium-67 citrate and technetium-99m tetrofosmin scan to detect Hodgkin’s disease
Springer Science and Business Media LLC - Tập 17 - Trang 439-442 - 2003
Feng-Yuan Liu, Yu-Chien Shiau, Ruoh-Fang Yen, Jhi-Joung Wang, Shung-Tai Ho, Chia-Hung Kao
Objective: The purpose of this study was to compare the usefulness of gallium-67 citrate (67Ga) and technetium-99m tetrofosmin (Tc-TF) scan to detect Hodgkin’s disease (HD).Methods: In this study, 24 patients with HD underwent67Ga and Tc-TF scan before receiving any therapy.Results:67Ga scan could detect HD in all 24 (100%) patients. Tc-TF scan could detect HD in 22/24 (91.6%) pat...... hiện toàn bộ
Phantom study of fusion image of CT and SPECT with body-contour generated from external Compton scatter sources
Springer Science and Business Media LLC - Tập 14 - Trang 271-277 - 2000
Kazuyoshi Suga, Naofumi Matsunaga, Yasuhiko Kawakami, Mataichi Furukawa
A phantom study was conducted to evaluate the feasibility of body contour definition with Compton scatter photons from extemal sources of technetium-99m pertechnetate (Tc-99m) to create a fusion image of CT and SPECT images. External sources of 1 mCi (37 MBq) Tc-99m were placed on each collimator, and bodycontour SPECT images were obtained with an energy window of 100 keV±25% for detecting 90° and...... hiện toàn bộ
Comparison of skeletal segmentation by deep learning-based and atlas-based segmentation in prostate cancer patients
Springer Science and Business Media LLC - Tập 36 - Trang 834-841 - 2022
Kazuki Motegi, Noriaki Miyaji, Kosuke Yamashita, Mitsuru Koizumi, Takashi Terauchi
We aimed to compare the deep learning-based (VSBONE BSI) and atlas-based (BONENAVI) segmentation accuracy that have been developed to measure the bone scan index based on skeletal segmentation. We retrospectively conducted bone scans for 383 patients with prostate cancer. These patients were divided into two groups: 208 patients were injected with 99mTc-hydroxymethylene diphosphonate processed by ...... hiện toàn bộ
Completely inverse images in dual-isotope SPECT with TI-201 and I-123 MIBG in a patient with myocarditis
Springer Science and Business Media LLC - Tập 15 - Trang 277-280 - 2001

Dual-isotope myocardial SPECT in a female patient with idiopathic myocarditis showed completely inverse images in Tl-201 and I-123 MIBG SPECT. In the dual-isotope SPECT performed 13 days after her admission, Tl-201 SPECT images showed reduced accumulation in the apex and normal accumulation in the other regions, whereas the corresponding I-123 MIBG SPECT images showed normal findings in the apex a...... hiện toàn bộ
