Personalized antenna pathways for enhancing safety and efficacy: optimizing microwave ablation outcomes in hepatic tumor treatments

Amirreza Heshmat, Rance Tino, Caleb S. O’Connor, Jéssica Albuquerque Marques Silva et autres

Microwave ablation (MWA) is a minimally invasive technique for treating malignant liver tumors. Achieving an adequate minimal ablative margin (MAM) of at least 5 mm prevents tumor progression and recurrence. However, challenges in consistently achieving adequate MAM due to factors such as …

Identification of A0 minimum ablative margins for colorectal liver metastases: multicentre, retrospective study using deformable CT registration and artificial intelligence-based autosegmentation

Iwan Paolucci, Jéssica Albuquerque Marques Silva, Yuan‐Mao Lin, Gregor Laimer et autres

BACKGROUND: Several ablation confirmation software methods for minimum ablative margin assessment have recently been developed to improve local outcomes for patients undergoing thermal ablation of colorectal liver metastases. Previous assessments were limited to single institutions mostly at the place of development. The …

Image-Guided Ablation for Cholangiocarcinoma: Current Evidence and Future Directions

Jéssica Albuquerque Marques Silva, Iwan Paolucci, Kristy K. Brock, Bruno Calazans Odisio

Abstract Though the incidence of intrahepatic cholangiocarcinoma (ICC) is rare compared with other malignancies, its prevalence is increasing significantly worldwide. Intrahepatic cholangiocarcinoma is an aggressive tumor, typically presenting at an advanced stage and showing resistance to treatments. The primary cause of mortality …

Using Patient-Specific 3D Modeling and Simulations to Optimize Microwave Ablation Therapy for Liver Cancer

Amirreza Heshmat, Caleb S. O’Connor, Jéssica Albuquerque Marques Silva, Iwan Paolucci et autres

Microwave ablation (MWA) of liver tumors presents challenges like under- and over-ablation, potentially leading to inadequate tumor destruction and damage to healthy tissue. This study aims to develop personalized three-dimensional (3D) models to simulate MWA for liver tumors, incorporating patient-specific characteristics. The …

Feasibility of extracting critical diagnostic imaging report findings following percutaneous liver ablation with a large language model

Alexander Shieh, Iwan Paolucci, Jéssica Albuquerque Marques Silva, Kristy K. Brock et autres

Percutaneous liver ablation is a minimally invasive procedure to treat liver tumors. Postablation images are highly significant as they distinguish normal post-procedure changes from abnormalities, preventing unnecessary retreatment and confirming procedural quality. However, the cancer surveillance imaging reports after the procedure can …

Fully automated deep learning based auto-contouring of liver segments and spleen on contrast-enhanced CT images

Aashish Chandra Gupta, Guillaume Cazoulat, Mais Al Taie, Sireesha Yedururi et autres

Abstract Manual delineation of liver segments on computed tomography (CT) images for primary/secondary liver cancer (LC) patients is time-intensive and prone to inter/intra-observer variability. Therefore, we developed a deep-learning-based model to auto-contour liver segments and spleen on contrast-enhanced CT (CECT) images. We …

Incidental Ring-hyperenhancing Liver Micronodules at CT Hepatic Arteriography−guided Percutaneous Thermal Ablation of Colorectal Liver Metastases

Jéssica Albuquerque Marques Silva, Yuan‐Mao Lin, Iwan Paolucci, Caleb S. O’Connor et autres

CT during hepatic arteriography (CTHA) is a highly sensitive imaging method for detecting colorectal liver metastases (CLMs), which supports its use during percutaneous thermal liver ablation. In contrast to its high sensitivity, its specificity for incidental small CLMs not detected at preablation …
