Prostatic Utricle Cysts as a Potential Pitfall in PSMA PET/CT Interpretation.
Clin Nucl Med
September 2024

A 60-year-old man with T2aN0M0 prostate cancer underwent intensity-modulated radiotherapy targeting the prostate and seminal vesicles. Experiencing biochemical recurrence after 6 years, 68 Ga-PSMA-11 PET/CT revealed focal radioactivity in the posterior midline of the prostate, identified as a prostatic utricle cyst on subsequent MRI. Similar findings appeared in a previous 18 F-piflufolastat PET/CT, with negative biopsy results.

Article Synopsis
- * I-131 scans are essential for monitoring thyroid remnants, residual disease, and potential recurrences, relying on the sodium-iodide symporter for iodine uptake.
- * This review discusses cases from our department where false-positive I-131 uptake occurred in conditions like vertebral hemangioma, lipoma, sinusitis, teratoma, and uterine leiomyoma.
Microgram BaCl2 ablation targets for trapped ion experiments.

Trapped ions for quantum information processing have been an area of intense study due to the extraordinarily high fidelity operations that have been reported experimentally. Specifically, barium trapped ions have been shown to have exceptional state-preparation and measurement fidelities. The 133Ba+ (I = 1/2) isotope in particular is a promising candidate for large-scale quantum computing experiments.

Background: F-FDG PET/CT is performed for the assessment of radioactive iodine non-avid disease in patients with DTC. In patients prepared by THW, increased pituitary uptake of F-FDG in the absence of pituitary disease may reflect the physiological activation of pituitary thyrotroph cells by hypothyroidism. This study aimed to compare pituitary F-FDG uptake in patients with DTC under THW vs.

Alzheimer's disease (AD) is a neurodegenerative disorder with increasing global prevalence and accounts for over half of all dementia cases. Early diagnosis is paramount for not only the management of the disease, but also for the development of new AD treatments. The current golden standard for diagnosis is performed by positron emission tomography (PET) scans with the tracer [C]Pittsburg Compound B ([C]PiB), which targets amyloid beta protein (A) that builds up as plaques in the brain of AD patients.
