The aim of this study was to describe the use of (99m)Tc-anti-TNF-α scintigraphy for detecting inflammation of the sacroiliac joints in a patient with non-radiographic axial spondyloarthritis. A 47-year-old female patient, non-smoker and non-drinker, complained of a low back pain inflammation, which began 4 years before her condition have exacerbated to morning stiffness and anterior uveitis in the last 6 months. Initially diagnosed as mechanical low back pain, she irregularly took non-steroidal anti-inflammatory drugs and corticosteroids, without significant long-lasting results. Radiographic findings were negative. There was increased uptake of (99m)Tc-anti-TNF-α in an area corresponding to the topography of ileum and sacroiliac right joint upon (99m)Tc-anti-TNF-α scintigraphy. Magnetic resonance imaging (MRI), the most used image diagnosis tool, showed minimum impregnation of gadolinium in the right sacroiliac joint and at the iliac face of the inferior third of the right sacroiliac joint. We suggest that (99m)Tc-anti-TNF-α can facilitate early diagnosis of patients with non-radiographic axial spondyloarthritis. More studies are now ongoing.
The thyroid is a rare site for finding tumor metastases. Renal, colorectal, pulmonary, and mammary origin are the most frequent primary neoplasms. Clinical suspicion, early diagnosis, and active surveillance are important during follow-up.

Purpose: Glomerular filtration rate (GFR) measured by dynamic renal scintigraphy (Gates method) is used in this study as the standard to investigate the applicability of two creatinine (Cr)-based GFR estimation equations in Chinese patients of different genders, age groups, and GFR stages diagnosed with neurogenic bladder (NB).
Methods: GFR values were measured using Tc-DTPA renal dynamic imaging, the new serum creatinine (Cr)-based chronic kidney disease epidemiology collaborative group (CKD-EPI) equation, and the equation for the estimated GFR of CKD patients in China, which were designated as sGFR, EPI-GFR, and cGFR, respectively. Pearson's correlation and linear regression were used to compare the differences, absolute differences, precision, and accuracies of the results of the two equations with sGFR to determine the formula offering better performance for the assessment of patients with NB.
Schwannomas are peripheral nerve sheath tumors that rarely arise from autonomic nerves of the pleural lining. Most often, they present as slow-growing tumors and are asymptomatic. Herein, we describe the case of an elderly male patient who presented with severe chest pain.

Mental health disorders emerge from complex interactions among neurobiological processes across multiple scales, which poses challenges in uncovering pathological pathways from molecular dysfunction to neuroimaging changes. Here, we proposed a multiscale fusion (mFusion) method to evaluate the relevance of each gene to the neuroimaging traits of mental health disorders. We combined gene-neuroimaging associations with gene-positron emission tomography (PET) and PET-neuroimaging associations using protein-protein interaction networks, where various genes traced by PET maps are involved in neurotransmission.
Background: Fibroblast activation protein (FAP) is an attractive target for cancer theranostics. Although FAP-targeted nuclear imaging demonstrated promising clinical results, only sub-optimal results are reported for targeted radionuclide therapy (TRT). Preclinical research is crucial in selecting promising FAP-targeted radiopharmaceuticals and for obtaining an increased understanding of factors essential for FAP-TRT improvement.
