Management of Challenging Radioiodine Treatment Protocols: A Case Series and Review of the Literature.

Radioactive iodine (RAI) therapy with I is the standard of care for treatment in many patients with differentiated thyroid cancer. Because I is typically administered as a pill, and much of its radioactivity is excreted via the urine, there can be challenges in patients who cannot swallow pills, absorb iodine via the gastrointestinal tract, or eliminate RAI via the urine (i.e.

Ga-PSMA-11 PET/MRI: determining ideal acquisition times to reduce noise and increase image quality.

Background: In this study, we investigate the impact of increased PET acquisition time per bed position on lesion detectability, standard uptake value, and image noise in Ga-PSMA-11 PET/MRI scans.

Methods: Scans of twenty patients were analyzed in this study. Patients were injected with Ga-PSMA-11 (mean, 5.

Direction-specific disruption of subcortical visual behavior and receptive fields in mice lacking the beta2 subunit of nicotinic acetylcholine receptor.

Retinotopic mapping is a basic feature of visual system organization, but its role in processing visual information is unknown. Mutant mice lacking the beta2 subunit of nicotinic acetylcholine receptor have imprecise maps in both visual cortex (V1) and the superior colliculus (SC) due to the disruption of spontaneous retinal activity during development. Here, we use behavioral and physiological approaches to study their visual functions.
