Ten patients who had been splenectomized for trauma between 1 and 11 years previously were studied by computed tomography (CT) and radionuclide scanning with 99Tcm tin colloid on the same day. Computed tomography detected splenic tissue in three patients. Radionuclide scanning detected splenic tissue in eight patients, including two cases of typical splenosis not identified by CT. Radionuclide scanning was found to be more sensitive in the detection of residual splenic tissue than CT.

Cancer remains a leading cause of mortality, with aggressive, treatment-resistant tumors posing significant challenges. Current combination therapies and imaging approaches often fail due to disparate pharmacokinetics and difficulties correlating drug delivery with therapeutic response. In this study, we developed radionuclide-activatable theranostic nanoparticles (NPs) comprising folate receptor-targeted bimetallic organo-nanoparticles (Gd-Ti-FA-TA NPs).

Purpose: To evaluate the added value of additional Ga-FAPI PET/CT following CT for primary staging, detection of postoperative recurrence, and management of gastric cancer patients.
Methods: We retrospectively included patients with gastric cancers who underwent contrast-enhanced computed tomography (ceCT), followed by Ga-FAPI PET/CT within 30 days. Ga-FAPI PET/CT was performed for initial staging or detection of postoperative recurrence.
Software Discrepancies in Radionuclide-Derived Left Ventricular Ejection Fraction.

Gated equilibrium radionuclide angiography (ERNA), or multigated acquisition scanning, is a well-established technique to monitor left ventricular ejection fraction (LVEF) in patients treated with potentially cardiotoxic chemotherapy. To determine the results of a true change in LVEF, low inter- and intrareader variability is important. The aim of this study was to investigate inter- and intrareader variability in LVEF measurements using 2 different commercially available software packages with cardiac MR (CMR) as a reference standard.

Purpose Of Review: This review aims to explore the clinical significance of atrial fluorodeoxyglucose (FDG) uptake observed in positron emission tomography (PET) scans, focusing on its association with atrial fibrillation (AF), cardiac sarcoidosis, and myocarditis. We discuss the implications of atrial uptake for patient management and prognosis.
Recent Findings: Recent studies have demonstrated that atrial FDG uptake is frequently present in patients with AF, particularly those with persistent AF, and is linked to increased risks of stroke and poorer outcomes after ablation.

Background: Temporal lobe epilepsy with isolated amygdala enlargement (TLE-AE) still lacks a definite characterization and controversies exist.
Methods: We conducted a retrospective study identifying brain MRI scans with isolated AE between 2015 and 2021. We collected clinical and paraclinical data of patients with TLE-AE and evaluated the outcome.
