The Role and Future of Artificial Intelligence in Robotic Image-Guided Interventions.

Artificial intelligence and robotics are transforming interventional radiology, driven by advancements in computer vision, robotics and procedural automation. Historically focused on diagnostics, AI now also enhances procedural capabilities in IR, enabling future robotic systems to handle complex tasks such as catheter manipulation or needle placement with increasing precision and reliability. Early robotic systems in IR demonstrated improved accuracy in both vascular and percutaneous interventions, though none were equipped with automatic decision-making.

Imaging in France: 2024 Update.

Radiology in France has made major advances in recent years through innovations in research and clinical practice. French institutions have developed innovative imaging techniques and artificial intelligence applications in the field of diagnostic imaging and interventional radiology. These include, but are not limited to, a more precise diagnosis of cancer and other diseases, research in dual-energy and photon-counting computed tomography, new applications of artificial intelligence, and advanced treatments in the field of interventional radiology.

Artificial intelligence in interventional radiology: Current concepts and future trends.

While artificial intelligence (AI) is already well established in diagnostic radiology, it is beginning to make its mark in interventional radiology. AI has the potential to dramatically change the daily practice of interventional radiology at several levels. In the preoperative setting, recent advances in deep learning models, particularly foundation models, enable effective management of multimodality and increased autonomy through their ability to function minimally without supervision.

Clinical value of sequential circulating tumor DNA analysis using next-generation sequencing and epigenetic modifications for guiding thermal ablation for colorectal cancer metastases: a prospective study.

Introduction: While thermal ablation is now a standard treatment option for oligometastatic colorectal cancer patients, selecting those who will benefit most from locoregional therapies remains challenging. This proof-of-concept study is the first to assess the feasibility of routine testing of ctDNA before and after thermal ablation with curative intent, analyzed by next-generation sequencing (NGS) and methylation specific digital droplet PCR (ddPCR). Our prospective study primary objective was to assess the prognostic value of ctDNA before thermal ablation.

Genicular artery embolization for knee osteoarthritis: Results of the LipioJoint-1 trial.

Purpose: The purpose of this study was to evaluate the safety and efficacy of transient genicular artery embolization (GAE) using an ethiodized oil-based emulsion for the treatment of knee osteoarthritis (KOA).

Materials And Methods: This prospective, single-arm, open-label, multicenter, first-in-human cohort trial was registered on ClinicalTrials.gov (NCT04733092).

Repeat Prostatic Artery Embolization with the Addition of a Liquid Embolic Agent: Short-term Results.

Rationale And Objectives: The long-term effectiveness of prostatic artery embolization (PAE) can be hampered by the recanalization of the previously embolized prostatic arteries (PA). The use of a liquid embolic agent (LEA) could limit this risk. The purpose of this study was to assess the safety and efficacy of repeat PAE (rePAE) using a LEA (Squid Peri) coupled with microspheres in patients experiencing recurring symptoms after initial embolization.

Exploring a Novel Technique to Tackle the Shortage of Devices for Hepatic Arterial Infusion Chemotherapy: Early Results of an Alternate Approach for Percutaneous Arterial Port Catheter Placement.

Dedicated catheters for hepatic arterial infusion chemotherapy were removed from the market. The purpose of this study was to assess the results of a novel approach to overcome the shortage of dedicated catheters for hepatic arterial infusion chemotherapy in the treatment of colorectal cancer liver metastases. We retrospectively included patients who underwent a percutaneous placement of a hepatic intra-arterial port catheter in a single tertiary center from February 2021 to June 2022.

PERcutaneous transhepatic CHOLangioscopy using a new single-operator short cholangioscope (PERCHOL): European feasibility study.

Objectives: A new short device for percutaneous endoscopic cholangioscopy was recently developed. However, feasibility and safety has not yet been evaluated. The aim of this study was to assess clinical success, technical success, and adverse events (AEs).

Treatment with selective transcatheter arterial embolization of a ruptured profunda artery perforator after internal thigh liposuction: a case report.

Background: Hemorrhage is an uncommon complication of liposuction that may be trauma-induced by the cannula on the subcutaneous perforators. It usually resolves spontaneously with external compression and results in mild to moderate ecchymosis on the liposuction site. However, in sporadic cases, active bleeding may persist and require urgent intervention for hemostasis.

Benefits of Repeat Prostatic Artery Embolization on Persistent or Recurrent Lower Urinary Tract Symptoms in Patients with Benign Prostatic Hyperplasia.

Objectives: To evaluate the benefits of repeat prostatic artery embolization (rePAE) for patients with persistent or recurrent symptoms after initial prostatic artery embolization (PAE).

Materials And Methods: This is a single-center retrospective study of all patients who underwent a rePAE between December 2014 and November 2020 for persistent or recurrent lower urinary tract symptoms. Symptoms were assessed before and after PAE and rePAE, using the International Prostate Symptom Score and quality of life (QoL) questionnaires.

Embolic Decision Making in Musculoskeletal Embolization.

In his pioneering work, Okuno and colleagues demonstrated the benefit of musculoskeletal (MSK) embolization, using imipenem as an embolic agent, in various diseases such as knee osteoarthritis (KOA), adhesive capsulitis (AC), tennis elbow and other sports injuries. As imipenem is a last-resort, broad spectrum antibiotic, its use is often not feasible depending on countries and their drug regulation. Since then, several other studies have used other material products such as microparticles or liquid embolics.

Long-term outcomes of prostate artery embolization for acute urinary retention: An analysis of 88 patients.

Purpose: The purpose of this study was to assess long-term outcome of prostate artery embolization (PAE) in patients presenting with acute urinary retention related to benign prostatic hyperplasia.

Materials And Methods: All consecutive patients who underwent PAE for acute urinary retention due to benign prostatic hyperplasia from August 2011 to December 2021 in a single institution were retrospectively included. There were 88 men with a mean age of 72 ± 12 (standard deviation [SD]) years (range: 42-99 years).

Artificial intelligence in diagnostic and interventional radiology: Where are we now?

The emergence of massively parallel yet affordable computing devices has been a game changer for research in the field of artificial intelligence (AI). In addition, dramatic investment from the web giants has fostered the development of a high-quality software stack. Going forward, the combination of faster computers with dedicated software libraries and the widespread availability of data has opened the door to more flexibility in the design of AI models.

Ruptured pulmonary artery pseudoaneurysm treated with stent graft: case report and literature review.

Background: Hemoptysis is a severe condition, associated with a high mortality rate from asphyxiation. Less than 5% of cases come from the pulmonary arterial circulation and large pseudoaneurysm are rarely treatable by stent graft.

Case Presentation: We present the case of a 74-year-old man who suffered from a new onset of hemoptysis despite a prior bronchial artery embolization.
