A 65-year-old man, who denied a smoking history, presented with chest distress and pain persisting for over a week. A contrast-enhanced chest CT scan revealed a large irregular mass in the right thoracic cavity with heterogeneous enhancement. The 18F-FDG PET/CT showed a large mass in the right thoracic cavity with heterogeneous markedly high FDG uptake.

Egea) for China were identified. Four species were identified by morph-anatomical, chemical, and phylogenetic analyses by combining two gene loci (ITS and LSU).

Gallium-68-labeled fibroblast activation protein inhibitor (FAPI) targets tumor stroma, leading to high accumulation across cancer types. The purpose of this study was to conduct a meta-analysis to compare the diagnostic performances of Ga-FAPI PET/CT and FDG PET/CT in detecting PM on the basis of studies providing head-to-head comparisons between the two tests.

However, PET/CT using prostate-specific membrane antigen (PSMA) ligands is increasingly recognized as a means of evaluating disease extent in patients with PCa, including use as a possible stand-alone test in high-risk patients. The purpose of this study is to compare the diagnostic performance of Ga-PSMA-11 PET/CT with that of Tc-MDP BS for the detection of bone metastases in patients with PCa.

Methods: A total of 140 outpatients meeting CP/CPPS diagnostic and research criteria in the Second Affiliated Hospital of Xi'an Jiaotong University were randomly divided into groups A (blank control), B (BFES intervention), C (SC intervention) and D (BFES+SC intervention), 35 cases in each group. The patients in group A were left untreated, while those in groups B, C and D received BFES, SC and BFES+SC, respectively, all for 12 weeks.
Bone tracer uptake related to ureteral stones has been reported several times before. We present a right ureteral stone mimicking abnormal focal sacral uptake on planar scan in a patient with rectal cancer. This case highlights the necessity of performing SPECT/CT to ascertain the origin of abnormal focal sacral uptake on planar scan, especially in patients with a history of kidney stones.

Whether PET/CT with TSH stimulation (sPET/CT) had better diagnostic performance than PET/CT without TSH stimulation (nsPET/CT) in this scenario was also evaluated.
Methods: PubMed and Embase databases were searched for eligible studies from January 2001 to December 2018.
Objective: Negative Tc-pertechnetate uptake of the thyroid bed indicates the absence or a small volume of remnant thyroid tissue (RTT) after total thyroidectomy (TT). The aim of this study is to evaluate the predictive value of negative Tc-pertechnetate scintigraphy for excellent response (ER) to radioactive iodine therapy (RIT) in low- to intermediate-risk differentiated thyroid cancer (DTC) patients.
Patients: One-hundred and eighty-nine low- to intermediate-risk DTC patients who underwent TT, RIT with a single dose of 30 mCi and suppressive therapy with thyroid-stimulating hormone (TSH) from July 2015 to February 2016 in our hospital were retrospectively evaluated.
