Purpose: To determine if there are differences in hepatic distribution of embolic particles following infusion with a standard end-hole catheter versus an antireflux microcatheter.
Materials And Methods: This prospective study included nine patients (age, 48-86 y) enrolled for treatment of hepatocellular carcinoma (n = 6), liver-dominant metastatic disease (n = 2), or intrahepatic cholangiocarcinoma (n = 1) with resin yttrium-90 ((90)Y) microspheres. Before (90)Y treatment, each patient received two same-day sequential lobar infusions of technetium 99m ((99m)Tc) macroaggregated albumin (MAA) via a conventional end-hole catheter and an antireflux microcatheter positioned at the same location.
Purpose: Computed tomography (CT) remains the gold standard for delineation of tumor volumes for radiotherapy (RT) planning. However, positron emission tomography (PET) overlay on CT has shown to impact the gross target volume (GTV), decrease intraobserver variability, and change the treatment planning in a significant number of patients. The objective of this study was to evaluate the influence and accuracy of FDG PET in GTV definition as a complementary modality to CT for patients with non-small-cell lung carcinoma at Vanderbilt University Medical Center.

- The study investigates the effects of selective matrix metalloproteinase inhibition (MMPi) while sparing MMP-1 on left ventricle (LV) remodeling in a pig model of congestive heart failure.
- Selective MMPi reduced LV peak wall stress and improved preload recruitable stroke work compared to rapid pacing alone, indicating potential benefits for heart function.
- Findings suggest that targeting specific MMP species for inhibition could be a more effective therapeutic approach for treating congestive heart failure.
