Squamous cell carcinoma of unknown primary continues to be a diagnostic challenge. We present a case where a novel molecular imaging agent aided the identification of additional lesions missed on traditional imaging, ultimately leading to diagnosis and a change in management.

Retinal ganglion cells (RGCs) are highly compartmentalized neurons whose long axons serve as the sole connection between the eye and the brain. In both injury and disease, RGC degeneration occurs in a similarly compartmentalized manner, with distinct molecular and cellular responses in the axonal and somatodendritic regions. The goal of this study was to establish a microfluidic-based platform to investigate RGC compartmentalization in both health and disease states.

Objective: CXCR4 and integrin αβ play important roles in tumor biology and are highly expressed in multiple types of tumors. This study aimed to synthesize, preclinically evaluate, and clinically validate a novel dual-targeted PET imaging probe Ga-pentixafor-c(RGDfK) for its potential in imaging tumors.
Methods: The effects of Ga-pentixafor-c(RGDfK) on cell viability, targeting specificity, and affinity were assessed in the U87MG cells.

Purpose: Cardiac noradrenergic denervation visualized by meta-[I]iodobenzylguanidine ([I]MIBG) imaging supports the diagnosis of Parkinson's disease (PD). Recently, meta-[F] fluorobenzylguanidine ([F]MFBG) PET demonstrated favorable imaging characteristics compared with [I]MIBG scintigraphy for neuroendocrine tumors. We assessed [F]MFBG dosimetry and myocardial pharmacokinetics in healthy controls and PD patients.

Adrenal cysts are rare lesions that are increasingly discovered incidentally during radiological examinations conducted without suspicion of adrenal disease. Typically benign, hormonally nonfunctional, and asymptomatic, these lesions may occasionally manifest mass effect symptoms such as pain or abdominal discomfort, particularly in large cysts. Management approaches vary from no follow-up to hormonal investigation, imaging follow-up, or adrenalectomy, especially if the cyst is growing or exhibits an atypical appearance.

Background The prognostic value of baseline visual emphysema scoring at low-dose CT (LDCT) in lung cancer screening cohorts is unknown. Purpose To determine whether a single visual emphysema score at LDCT is predictive of 25-year mortality from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease (CVD). Materials and Methods In this prospective cohort study, asymptomatic adults aged 40-85 years with a history of smoking underwent baseline LDCT screening for lung cancer between June 2000 and December 2008.
