PVE correction in PET from PVE affected images

2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC), 2009
Partial Volume Effect (PVE) in Positron Emission Tomography (PET), as a consequence of the PET limited spatial resolution, causes underestimation of radiotracer uptake in oncological lesions and needs to be corrected. Aim of this work was to develop a method for PVE correction of PET-CT oncological studies, based on curves of Recovery Coefficients (RC)

PVE Correction in PET-CT Whole-Body Oncological Studies From PVE-Affected Images

IEEE Transactions on Nuclear Science, 2011
Partial Volume Effect (PVE) in PET-CT oncological studies affects the estimation of quantitative parameters useful for lesion malignancy differentiation and for monitoring disease and response to therapy. The aim of this work was to investigate the clinical feasibility and accuracy of PVE correction methods based on Recovery Coefficients (RC) as ...

Portal Vein Embolization (PVE) and Partial TIPE ALPPS: Beyond the Limitations of PVE

2020
Portal vein embolization (PVE) if often used before major hepatectomy to increase the volume of the future liver remnant (FLR) and thus prevent postsurgical liver failure. In this chapter, the history, methods, efficacy, and limitations of PVE are summarized, and a potential breakthrough in the limitations of PVE is described.

Islamist Governance and PVE Policy in Indonesia

2023
Abstract In Chapter 14, Cameron Sumpter and Yuslikha Kusama Wardhani look at preventing and countering violent extremism (P/CVE) in Indonesia and Islamist political actors’ opposition to such policies. Noting that politically active Islamists may have very few connections with those willing to carry out acts of terrorism, many remain ...

Two-Boson Exchange Corrections in PVES

AIP Conference Proceedings, 2011
I summarize the recent progress on the understanding of the two‐boson exchange effect in the parity‐violating scattering. I report the results obtained in a hadronic model and a model using Nucleon General Parton Distributions(GPDS), respectively.

PVES: Powered Visualizer for Earth Environmental Science

IEEE Systems Journal, 2008
In this paper, we propose a powered visualizer for Earth environmental science (PVES) which can accommodate three-dimensional (3D) datasets. Though a data integration system called the information fusion reactor for Earth environmental science (IFRES) is being developed at the Institute of Industrial Science at the University of Tokyo, PVES is a part ...

Application of PVE in Hepatic Surgery

2015
Portal vein embolization (PVE) is a method for selectively embolizing a branch of the portal vein, changing the hemodynamics of the portal vein, or increasing portal vein flow in a non-embolized liver lobe, resulting in non-embolized lobe regeneration and embolized lobe atrophy.

ALPPS Procedure in Insufficient Hypertrophy After Portal Vein Embolization (PVE)

World Journal of Surgery, 2016
AbstractBackgroundThe main limiting factor for major liver resections is the volume and function of the future remnant liver (FLR). Portal vein embolization (PVE) is now standard in most centers for preoperative hypertrophy of FLR. However, it has a failure rate of about 20–30 %. In these cases, the “Associating Liver Partition and Portal Vein Ligation

Sequential TACE and PVE for Hepatocellular Carcinoma

2011
Although hepatic resection is the treatment of choice for large hepatocellular carcinoma (HCC) whenever feasible, it is often precluded by the presence of underlying chronic liver disease. Portal vein embolization (PVE) has been introduced to extend the indications for major hepatic resection to increase the safety of the surgical procedure.
