Augmented reality-guided osteotomies for simulated mandibular reconstruction with fibular bone using virtual cutting guides and 3D navigation.

In the last decades, maxillomandibular reconstruction has been revolutionised by the use of free flaps and virtual surgical planning technologies. However, the currently available applied physical cutting guides provide no intraoperative flexibility, and adjustments based on intraoperative findings are not possible. A novel augmented reality (AR)-guided technique is presented that allows for quick intraoperative surgical planning adaptations.

In Vitro Investigation of Microcatheter Behavior During Microsphere Injection in Transarterial Radioembolization.

Purpose: To experimentally investigate the behavior of a clinically used microcatheter during transarterial radioembolization (TARE) microsphere injection in a successively bifurcating model.

Materials And Methods: A symmetrical phantom was developed which bifurcated 3 times into 8 outlets. A blood-mimicking fluid was pumped through the phantom using a physiological representative waveform.

Transarterial radioembolization: a systematic review on gaining control over the parameters that influence microsphere distribution.

Transarterial radioembolization (TARE) is an established treatment modality for patients with unresectable liver cancer. However, a better understanding of treatment parameters that influence microsphere distribution could further improve the therapy. This systematic review examines and summarizes the available evidence on intraprocedural parameters that influence the microsphere distribution during TARE as investigated by in vivo, ex vivo, in vitro and in silico studies.

Bone visualization of the cervical spine with deep learning-based synthetic CT compared to conventional CT: A single-center noninferiority study on image quality.

Purpose: To investigate whether the image quality of a specific deep learning-based synthetic CT (sCT) of the cervical spine is noninferior to conventional CT.

Method: Paired MRI and CT data were collected from 25 consecutive participants (≥ 50 years) with cervical radiculopathy. The MRI exam included a T1-weighted multiple gradient echo sequence for sCT reconstruction.
