Patient-specific 3-dimensional lung modelling: next-generation imaging helps guide precise surgical resection

Abstract

Recent strides have allowed the consolidation of routine imaging modalities with highly accurate reconstruction software to aid the operating surgeon generate patient-specific three-dimensional models. In this preliminary report, we describe our initial experience using a patient-specific reconstruction software to guide surgical resection for 2 patients with non-small-cell lung cancer. Digital imaging and communications in medicine data from patient chest CT scans was configured into IQQA BodyImaging Lung software to generate highly accurate maps of airways, vessels and segments as well as estimates of lung volumes. Models generated aided us in planning appropriate lung cancer resection procedures.

Application of a three‐dimensional visualization model in intraoperative guidance of percutaneous nephrolithotomy

“…The current PCNL 3D model is constructed by the surface rendering method 16–18 . Through its functions of rotating, scaling, and segmenting the region of interest, the 3D model helps to better understand the renal stone and collection system and can also intuitively display the details of anatomical variation to assist in the formulation of an individualized surgical scheme 19 . Our preoperative planning focused on the following aspects: (i) optimization of the puncture path; (ii) ultrasound image simulation: to help the surgeon find and identify the target renal calyx quickly; (iii) surgical simulation: to simulate the effect of stone removal and the possibility of residual stones.…”

How to distinguish thoracic and cervical lymph nodes during minimally invasive esophagectomy

“…With the continuous development of digital medicine, artificial intelligence three‐dimensional (3D) reconstruction technology has been widely used in clinics, achieving visualization of internal anatomical structures of human organs, digitization of disease diagnosis and treatment, and precision of surgical operations. 3D reconstruction technology is based on two‐dimensional (2D) images and integrates and reconstructs 3D images 27 . It can reconstruct the 3D anatomical structure of the human body based on computed tomography (CT), magnetic resonance imaging (MRI), and other imaging data to fully understand the nature of the lesion and the 3D structure relationship of the surrounding tissues.…”

According to reports, IQQA 3D reconstruction technology (EDDA Technology, Princeton, NJ, USA) 28 uses 3D visualization technology to reconstruct complex anatomical structures during precise segmentectomy, segmental liver resection, and partial nephrectomy, thereby providing an important reference for formulating surgical plans.…”
