Diagnostic value of 18F-FDG PET/CT in patients with biochemical recurrent prostate cancer and negative 68Ga-PSMA PET/CTEuropean Journal of Nuclear Medicine - Tập 48 - Trang 2970-2977 - 2021

68Ga-PSMA PET/CT has a high detection rate in prostate cancer patients with biochemical recurrence (BCR). However, few studies have reported other imaging methods for BCR with negative 68Ga-PSMA PET/CT findings. We investigated the value of 18F-FDG compared with 68Ga-PSMA and identified BCR patients with 68Ga-PSMA-negative findings who are most likely to benefit from 18F-FDG PET/CT. Seventy-two BC...... hiện toàn bộ
Effects of diuretics on iodine uptake in non-toxic goitre: comparison with low-iodine dietEuropean Journal of Nuclear Medicine - Tập 30 - Trang 1270-1272 - 2003

Low-iodine diet has been employed to achieve iodine depletion prior to radioiodine (RI) therapy. However, treatment with diuretics may be more effective than low-iodine diet in causing iodine depletion and subsequent increase in RI uptake by the thyroid. Fifty-five patients with non-toxic goitre were given 0.20 MBq RI p.o. on the first day of the study and thyroid uptake was measured. In 15 patien...... hiện toàn bộ
The natural history of takotsubo syndrome: a two-year follow-up study with myocardial sympathetic and perfusion G-SPECT imagingEuropean Journal of Nuclear Medicine - Tập 44 - Trang 267-283 - 2016

To investigate changes in sympathetic activity, perfusion, and left ventricular (LV) functionality in takotsubo cardiomyopathy (TTC) patients from onset (T0) to post-onset conditions at 1 month (T1), 1-2 years (T2, T3). Twenty-two patients (70 ± 11 years) underwent serial gated single photon emission tomography (G-SPECT) studies with 123I-mIBG and 99mTc-Sestamibi. Statistics were performed using A...... hiện toàn bộ
Value of the free triiodothyronine index in the diagnosis of hyperthyroidismEuropean Journal of Nuclear Medicine - Tập 5 - Trang 119-124 - 1980
Jan D. Wiener
Normalized T4 (T4N), total T3, T3 resin sponge uptake (T3U) and the response of TSH to TRH were determined in 264 patients sent for diagnosis of thyroid function. Many of these patients were diagnostic problem cases. Those with disease or medication known to invalidate the TRH test, but not those with abnormal thyroid hormone binding capacity in serum, were excluded. A free T3 index (FT3 index) wa...... hiện toàn bộ
Predicting the biodistribution of radiolabeled cMORF effector in MORF-pretargeted miceEuropean Journal of Nuclear Medicine - Tập 34 - Trang 237-246 - 2006

Pretargeting with phosphorodiamidate morpholino oligomers (MORFs) involves administration of a MORF-conjugated anti-tumor antibody such as MN14 as a pretargeting agent before that of the radiolabeled complementary MORF (cMORF) as the effector. The dosages of the pretargeting agent and effector, the pretargeting interval, and the detection time are the four pretargeting variables. The goal of this ...... hiện toàn bộ
In-vivo imaging characteristics of two fluorinated flumazenil radiotracers in the ratEuropean Journal of Nuclear Medicine - Tập 36 - Trang 958-965 - 2009

[11C]Flumazenil shows promise as a clinical and research PET radiotracer to image changes in GABAA central benzodiazepine receptor (cBZR), but its widespread use has been limited by practical limitations of [11C]. This study evaluated the imaging characteristics of two fluorinated PET radiotracers in rats in vivo: [18F]fluoroflumazenil ([18F]FFMZ) and [18F]flumazenil ([18F]FMZ). PET acquisitions w...... hiện toàn bộ
