Abstract Minimally invasive image-guided tumor ablation techniques have been established as safe, effective methods to treat a variety of unresectable soft tissue tumors. Standard thermal ablation methods include radiofrequency ablation, microwave ablation, and cryoablation. However, newer non-thermal and/or non-invasive ablation techniques are now available as alternative options to treat soft tissue tumors, particularly those that are near critical structures or otherwise susceptible to thermal energy sink effects. The 4 types of emerging ablation techniques discussed in this review are as follows: irreversible electroporation, pulsed electric field, high-intensity focused ultrasound, and histotripsy. While the clinical trials evaluating the safety and efficacy of these ablation techniques are in their early stages, initial results are promising in the treatment of various cancers at different stages. These include potential synergistic effects when combined with chemotherapy and immunotherapy.

AbstractAlthough bronchial artery embolization (BAE) initially emerged as a critical minimally invasive image-guided procedure to manage massive hemoptysis regardless of underlying etiologies, there has been a growing interest in BAE to treat pulmonary malignancies within recent years. This article provides an in-depth exploration of bronchial artery anatomy, pathologies, imaging modalities in guiding effective BAE, and procedural pearls for successful intervention. The complexity of bronchial artery anatomy, including its variations and potential complications during embolization, necessitates thorough understanding and precise procedural techniques to optimize patient outcomes and minimize risks.
