Special Considerations and Techniques of Interventions in Lung Transplant Recipients
Lung transplant remains an important treatment option for patients with end-stage lung diseases providing improvement in survival rates and quality of life. Specialized considerations should be applied with interventions of lung transplant recipients as they host specific anatomic variations and high risk towards certain complications. In this article, we highlight the role of interventional radiology for lung transplant recipients along with discussion of interventional techniques. Specific emphasis is placed on describing and explaining the techniques pertained to the points of anastomosis, diagnosis and treatment of mal...

Magnetic Resonance-Guided Procedures: consensus on rationale, techniques, and outcomes
This article covers the main points of MR-guided hepatic tumor ablation as a representative of MR-guided procedures. Patient selection and appropriate equipment utilization are essential for successful MR-guided tumor ablation. Intra-procedural planning imaging enables the visualization of the tumor and surrounding anatomical structures in most cases without application of contrast agent, ensuring optimal planning of the applicator tract.

Percutaneous Robotics in Interventional Radiology
We report our experience in using the robotic device for the insertion of trocar needles in CT guided procedures. The majority of procedures were targeted organ biopsies in the chest abdomen or pelvis. The accuracy of needle placement after target adjustments did not significantly differ from those patients where a linear trajectory could be used.

Contrast-Enhanced Ultrasound for Image-Guided Procedures
Contrast-enhanced ultrasound (CEUS) uses intravenously injected gas microbubbles as a pure blood pool contrast agent to demonstrate blood flow and tissue perfusion at a much higher sensitivity than color Doppler and power Doppler ultrasound. CEUS has gained traction in abdominal diagnostic imaging for improved lesion detection and characterization and a complementary problem-solving tool to CT and MRI. In addition to its diagnostic applications, CEUS has also proven useful for pre-procedure planning, procedure guidance, and post-procedure evaluation.

CT navigation for percutaneous needle placement: How I do it
CT navigation (CTN) has recently been developed to combine many of the advantages of conventional CT and CT-fluoroscopic guidance for needle placement. CTN systems display real-time needle position superimposed on a CT dataset. This is accomplished by placing electromagnetic (EM) or optical transmitters/sensors on the patient and needle, combined with fiducials placed within the scan field to superimpose a known needle location onto a CT dataset. Advantages of CTN include real-time needle tracking using a contemporaneous CT dataset with the patient in the treatment position, reduced radiation to the physician, facilitation...

Image Fusion Technology in Interventional Radiology
Image fusion technology aims to improve patient outcomes for image-guided interventions by leveraging the strengths of multimodality imaging datasets. This most commonly involves the overlay or co-display of advanced cross-sectional imaging permitting freedom of device placement via conventional image guidance such as ultrasound, fluoroscopy and computed tomography. This can allow the interventionalist to target and treat lesions that would otherwise be difficult or impossible to visualize and access using conventional imaging guidance.

Advancements and Future Outlook of PET/CT-Guided Interventions
Advancements in minimally invasive technology, coupled with imaging breakthroughs, have empowered the field of interventional radiology to achieve unparalleled precision in image-guided diagnosis and treatment while simultaneously reducing periprocedural morbidity. Molecular imaging, which provides valuable physiological and metabolic information alongside anatomical localization, can expand the capabilities of image-guided interventions. Among various molecular imaging techniques, positron emission tomography (PET) stands out for its superior spatial resolution and ability to acquire quantitative data. (Source: Techniques...

Overcoming Barriers and Advancements in Endovascular Robotics: A Review of Systems and Developments
Endovascular robots have the potential to revolutionize the field of vascular interventions by enhancing procedural efficiency, accuracy, and standardization. They aim to reduce radiation exposure, as well as physical strain on operators and medical staff, while enabling precise navigation of catheters through challenging anatomical structures. However, the widespread adoption of these robots faces barriers, such as real estate constraints, setup time, limited range of compatible tools, and high costs.

Virtual and Augmented Reality in Interventional Radiology: Current Applications, Challenges, and Future Directions
Virtual Reality (VR) and Augmented Reality (AR) are emerging technologies with the potential to revolutionize Interventional Radiology (IR). These innovations offer advantages in patient care, interventional planning, and educational training by improving the visualization and navigation of medical images. Despite progress, several challenges hinder their widespread adoption, including limitations in navigation systems, cost, clinical acceptance, and technical constraints of AR/VR equipment. However, ongoing research holds promise, with recent advancements such as shape-sensing needles and improved organ deformation modeli...

Techniques for Embolization of the Ovarian Vein and Pelvic Reservoir
Pelvic venous disorders are a common and under diagnosed cause of chronic pelvic pain in women, presenting with chronic, non-cyclical pelvic pain for greater than six months and the presence of pelvic varicosities. Pelvic varices and ovarian vein reflux are a strong indicator of venous origin chronic pelvic and may benefit from embolization. This most commonly occurs in multiparous, premenopausal women with symptoms of gravity dependent pelvic pain and post coital pain. Additional causes of pelvic venous disorders include iliac vein compression, internal iliac vein reflux and renal vein compression, however for the purpose...
