“…Automated registration of the 3D model to CT grid was performed using computer vision and Vuforia 9.0.12 with the CT grid as the image target. Features on the CT grid can be reliably and quickly detected by Vuforia 12 , and studies have validated the accuracy of Vuforia on HoloLens (v1) 10 , 13 – 17 . Registration accuracies were not directly validated in this study; registration fidelity was confirmed visually by the operator based on complete alignment of the virtual gridlines with the physical gridlines.…”

“…Smartphone or tablet-based AR navigation platforms for CT-guided needle insertion have demonstrated sub-5 mm accuracies, decreased procedure times, and fewer intermediate CT scans 7 , 8 . 3D AR-assisted navigation systems using HoloLens (v1, Microsoft, Redmond, WA) have received unanimously positive feedback among operators for its potential to enhance safety, aid in execution, and improve depth perception and spatial understanding 9 , 10 . Although such systems show promise, no prior study to date has demonstrated the procedural effects of AR guidance using an optical see-through headset device through a systematic trial.…”

Out-of-plane lesions pose challenges for CT-guided interventions. Augmented reality (AR) headsets are capable to provide holographic 3D guidance to assist CT-guided targeting. A prospective trial was performed assessing CT-guided lesion targeting on an abdominal phantom with and without AR guidance using HoloLens 2. Eight operators performed a cumulative total of 86 needle passes. Total needle redirections, radiation dose, procedure time, and puncture rates of nontargeted lesions were compared with and without AR. Mean number of needle passes to reach the target reduced from 7.4 passes without AR to 3.4 passes with AR (p = 0.011). Mean CT dose index decreased from 28.7 mGy without AR to 16.9 mGy with AR (p = 0.009). Mean procedure time reduced from 8.93 min without AR to 4.42 min with AR (p = 0.027). Puncture rate of a nontargeted lesion decreased from 11.9% without AR (7/59 passes) to 0% with AR (0/27 passes). First needle passes were closer to the ideal target trajectory with AR versus without AR (4.6° vs 8.0° offset, respectively, p = 0.018). AR reduced variability and elevated the performance of all operators to the same level irrespective of prior clinical experience. AR guidance can provide significant improvements in procedural efficiency and radiation dose savings for targeting out-of-plane lesions.

“…Taking a step further is the development and adaptation of virtual reality and augmented reality. This allows to stereoscopically view 3D datasets in actual three-dimensional space, resulting in improved spatial understanding as well as procedure execution and safety, especially for inexperienced operators [ 227 , 228 ].…”

For patients with isolated liver metastases from colorectal cancer who are not candidates for potentially curative resections, non-surgical local treatments may be useful. Non-surgical local treatments are classified according to how the treatment is administered. Local treatments are applied directly on hepatic parenchyma, such as radiofrequency, microwave hyperthermia and cryotherapy. Locoregional therapies are delivered through the hepatic artery, such as chemoinfusion, chemoembolization or selective internal radiation with Yttrium 90 radioembolization. The purpose of this review is to describe the different interventional therapies that are available for these patients in routine clinical practice, the most important clinical trials that have tried to demonstrate the effectiveness of each therapy and recommendations from principal medical oncologic societies.

“…These technologies can be used to display trajectories more intuitively in actual 3D space, resulting in improved spatial understanding as well as procedure execution and safety. 71 , 72 However, accurate registration of these trajectories within patients will be essential for 3D-assisted virtual and holographic guidance. Promising results with AR-assisted guidance include decreased procedure time, reduced radiation dose, and enhanced performance of inexperienced operators.…”
