“…Note that the post-treatment condition can be obtained from medical images, thus allowing a real performance assessment, but also with CFD, allowing a predictive assessment. In numerical modeling, this simple comparison is convenient since the explicit representation of the virtual devices increases the computational times (and costs) (Morales et al, 2011;Larrabide et al, 2013).…”

“…All the clinical records and aneurysm morphological features were included as follows ( Table 1): Age, sex, hypertension, aneurysm size, aneurysm shape, size ratio (SR) and aspect ratio (AR) were collected [8] [9]. In this study, the aneurysm shape was divided into regular and irregular.…”

Objective: This study was designed to identify hemodynamic features of aneurysms prior to rupture in comparison with unruptured aneurysms. Materials and Methods: A retrospective data of four large unruptured aneurysms (pre-ruptured group) with sufficient films just pre-rupture was used. Matched with the same location and similar sizes, another four unruptured aneurysms (unruptured group) were in accordance with controls during the same time period and flow simulations were performed for hemodynamic analysis. Results: Compared with the unruptured group, the pre-ruptured group had significantly more irregular aneurysm shape, higher aspect ratio and lower aneurysm-averaged wall shear stress (p = 0.031, p = 0.039 and p = 0.042, respectively). Although pre-ruptured aneurysms had lower low wall shear stress (WSS) area and higher oscillatory shear index value, there was no significant difference between groups. Conclusions: Irregular shape, higher aspect ratio and low wall shear stress were relative with unruptured ICA aneurysms in predicting rupture. Those patients with these risk factors should be more prone to treatment even if with an unruptured aneurysm.

Medical image analysis has grown into a matured field challenged by progress made across all medical imaging technologies and more recent breakthroughs in biological imaging. The cross-fertilisation between medical image analysis, biomedical imaging physics and technology, and domain knowledge from medicine and biology has spurred a truly interdisciplinary effort that stretched outside the original boundaries of the disciplines that gave birth to this field and created stimulating and enriching synergies. Consideration on how the field has evolved and the experience of the work carried out over the last 15 years in our centre, has led us to envision a future emphasis of medical imaging in Precision Imaging. Precision Imaging is not a new discipline but rather a distinct emphasis in medical imaging borne at the cross-roads between, and unifying the efforts behind mechanistic and phenomenological modelbased imaging. It captures three main directions in the effort to deal with the information deluge in imaging sciences, and thus achieve wisdom from data, information, and knowledge. Precision Imaging is finally characterised by being descriptive, predictive and integrative about the imaged object. This paper provides a brief and personal perspective on how the field has evolved, summarises and formalises our vision of Precision Imaging for Precision Medicine, and highlights some connections with past research and current trends in the field.
