The os sustentaculi is a rare accessory bone of the ankle and foot region. We describe the imaging findings of a symptomatic os sustentaculi in a 49-year-old man. Its clinical significance and associated conditions are also briefly discussed.

Importance: Multiparametric magnetic resonance imaging (MRI), with or without prostate biopsy, has become the standard of care for diagnosing clinically significant prostate cancer. Resource capacity limits widespread adoption. Biparametric MRI, which omits the gadolinium contrast sequence, is a shorter and cheaper alternative offering time-saving capacity gains for health systems globally.

Importance: Merkel cell carcinoma (MCC) is typically caused by the Merkel cell polyomavirus (MCPyV) and recurs in 40% of patients. Half of patients with MCC produce antibodies to MCPyV oncoproteins, the titers of which rise with disease recurrence and fall after successful treatment.
Objective: To assess the utility of MCPyV oncoprotein antibodies for early detection of first recurrence of MCC in a real-world clinical setting.

This study aimed to identify brain activity modulations associated with different types of visual tracking using advanced functional magnetic resonance imaging techniques developed by the Human Connectome Project (HCP) consortium. Magnetic resonance imaging data were collected from 27 healthy volunteers using a 3-T scanner. During a single run, participants either fixated on a stationary visual target (fixation block) or tracked a smoothly moving or jumping target (smooth or saccadic tracking blocks), alternating across blocks.

Alpha oscillations have been implicated in the maintenance of working memory representations. Notably, when memorised content is spatially lateralised, the power of posterior alpha activity exhibits corresponding lateralisation during the retention interval, consistent with the retinotopic organisation of the visual cortex. Beyond power, alpha frequency has also been linked to memory performan ce, with faster alpha rhythms associated with enhanced retention.
