“…Pre-procedural CT angiogram [26] and pre-procedural MR angiography (MRA) [27] with different benefits are described but are not within the scope of this review. Several other studies propose variations of the intra-procedural CBCT [21,22,24,[28][29][30] and additional virtual injection methods [20] in order to improve identification of prostatic arteries and treatment techniques (Tabe 1).…”

“…This can simulate embolization by using virtual injection points on a 3D reconstruction of vasculature from the CBCT data. Barrel et al have shown that this technology can reduce the radiation dose by almost twofold [29] by reducing the number of DSAs needed. The software can also provide an overlay for the operator during fluoroscopy using the data from CBCT and provide a guide during cannulation (Fig.…”

Prostatic artery embolization (PAE) has proven to be an efficacious treatment for urinary symptoms of benign prostatic hyperplasia. PAE is performed in a complex and challenging anatomical field which may pose difficulties from procedural standpoint. Cone beam computed tomography (CBCT) has been proposed as an invaluable tool during the PAE procedure. A review of different techniques and advancements, as well as demonstration of CBCT benefits via a pictorial overview of the salient examples is lacking. The techniques of CBCT are discussed herein and the virtual injection technology as an advancement in CBCT is discussed. To show the merits of CBCT in PAE, a pictorial overview of various clinical scenarios is presented where CBCT can be crucial in decision making. These scenarios are aimed at showing different benefits including identification of the origin of the prostatic artery and avoiding non-target embolization. Other benefits may include ensuring complete embolization of entire prostate gland as angiographic appearance alone can be inconclusive if it mimics a severely thickened bladder wall or ensuring adequate embolization of the median lobe to provide relief from “ball-valve” effect. Further examples include verification of embolization of the entire prostate when rare variants or multiple (> 2) arterial feeders are present.

“…[14][15][16][17][18][19] One study evaluating the integration of AI-driven virtual injection software during CBCT-guided prostatic artery embolization procedures revealed that implementation of virtual injection significantly reduced various radiation exposure parameters compared to standard procedures as well as overall procedure time. 20 Further studies validating it's use in the hepatic setting is expected. Furthermore, suites combining multiple modalities may help to provide the capability to perform complex combined or staged procedures as well as scheduling flexibility by allowing any type of case to be performed in this IR suite.…”

Interventional Oncology (IO) stands at the forefront of transformative cancer care, leveraging advanced imaging technologies and innovative interventions. This narrative review explores recent developments within IO, highlighting its potential impact facilitated by artificial intelligence (AI), personalized medicine and imaging innovations. The integration of AI in IO holds promise for accelerating tumour detection and characterization, guiding treatment strategies and refining predictive models. Imaging modalities, including functional MRI, PET and cone beam CT are reshaping imaging and precision. Navigation, fusion imaging, augmented reality and robotics have the potential to revolutionize procedural guidance and offer unparalleled accuracy. New developments are observed in embolization and ablative therapies. The pivotal role of genomics in treatment planning, targeted therapies and biomarkers for treatment response prediction underscore the personalization of IO. Quality of life assessment, minimizing side effects and long-term survivorship care emphasize patient-centred outcomes after IO treatment. The evolving landscape of IO training programs, simulation technologies and workforce competence ensures the field’s adaptability. Despite barriers to adoption, synergy between interventional radiologists’ proficiency and technological advancements hold promise in cancer care.
