Article Synopsis
- The study aims to determine if the extracellular volume (ECV) fraction can effectively identify splenic involvement in lymphoma patients and enhance the diagnostic accuracy of standard CT scans.
- Researchers analyzed data from 135 lymphoma patients who underwent CT and PET/CT scans, categorizing them into those with and without splenic involvement based on ECV fraction and spleen characteristics.
- Findings indicate that the ECV fraction is a reliable marker for splenic involvement, and when combined with spleen vertical length greater than 13 cm, it significantly improves diagnostic performance compared to other methods.
Primary small cell neuroendocrine carcinomas are extremely rare heterogeneous neoplasms. We present 68 Ga-FAPI (fibroblast activation protein inhibitor) PET/CT findings of small cell neuroendocrine carcinoma of the gallbladder in a 57-year-old woman. This rare gallbladder small cell neuroendocrine carcinoma demonstrated intense tracer uptake on 68 Ga-FAPI PET/CT.

Patients with bone metastatic neoplasms who had undergone baseline bone SPECT/CT scanning before Sr-89 therapy (148 MBq Sr-89 chloride by an intravenous injection for each patient) between July 2011 and July 2018 were included. Bone SPECT/CT images were assessed by two readers independently.
