In vivo imaging and pharmacokinetics of percutaneously injected ultrasound and X-ray imageable thermosensitive hydrogel loaded with doxorubicin versus free drug in swine.

Intratumoral injections often lack visibility, leading to unpredictable outcomes such as incomplete tumor coverage, off-target drug delivery and systemic toxicities. This study investigated an ultrasound (US) and x-ray imageable thermosensitive hydrogel based on poloxamer 407 (POL) percutaneously delivered in a healthy swine model. The primary objective was to assess the 2D and 3D distribution of the hydrogel within tissue across three different needle devices and injection sites: liver, kidney, and intercostal muscle region.

Smartphone Technology for Applications in Image-Guided Minimally Invasive Interventional Procedures.

Smartphones contain powerful and enabling technology components that can be re-applied toward procedural tasks commonly used in everyday clinical image-guided therapies and minimally invasive procedures that use three-dimensional information and feedback during procedures. Smartphone applications are a relatively young field of research that have potential in interventional radiology (IR) toward improvement of accuracy and standardization for needle-based procedures like biopsy and ablation. This review explores the adaptation of smartphones' built-in sensors for virtual and augmented reality uses in IR.

Impact of Discordance Between MRI and US Volume Measurements on Prostate Fusion Biopsy Outcomes.

Purpose: To determine whether the difference between MRI-based and ultrasound (US)-based volume measurements are associated with MRI/US-targeted fusion-guided biopsy outcomes.

Materials And Methods: This retrospective, single-center study involved 4177 consecutive patients biopsied between 2010 and 2023 using both MRI/US-targeted fusion and systematic biopsy. Biopsies were indicated because of elevated prostate-specific antigen levels or abnormal multiparametric MRI results.
