Investigation of pelvic symmetry using CAD software
AbstractSevere pelvic fractures often prove difficult for surgeons as they require patient-specific surgical treatment plans and customized equipment. Developing virtual patient-specific 3D pelvis models would ease the surgical planning process and enable development of custom fixation plates. This paper aims to examine pelvic symmetry to conclude whether the contralateral side may be used as a reference model for the fractured side of the pelvis. Fourteen subjects with intact pelvises were involved in this study. CT scans of the pelvises were converted to 3D models and the right sides of the pelvises were reflected and aligned with the left sides. A deviation analysis was then performed for each set of models and results showed that the average root mean square (RMS) of values was 1.14 ± 0.26 mm and the average percentage of points below a deviation threshold of ± 2 mm was 91.9 ± 5.55%. The deviation color maps (DCMs) showed that the largest deviations were on the non-articular surfaces. The volume and surface area of each model were also examined and showed no significant diff erences between left and right sides. These results indicate that the pelvis displays bilateral symmetry and this concept can be used to develop fully intact patient-specific 3D pelvis models for fracture reconstruction using the unfractured contralateral side.Graphical Abstract
CONCLUSIONS: This new method allows operators to correct their own therapy plans and choices, customizing the treatment plan on the actual condition of the patient. Moreover, it makes all the rehabilitation process safer and can reduce the risk of failure, side effects and inconveniences for the patients. PMID: 31799661 [PubMed - in process]
Discussion/conclusionLes chirurgiens peuvent apprécier ces résultats pour déterminer un traitement postopératoire personnalisé qui assure la meilleure poursuite de vie pour le patient.
ConclusionSemi-quantitative assessment of PRH on admission CT scan allows to predict transfusion needs, hemostatic procedures, and worse outcome of severe trauma patients with pelvic fracture.
CONCLUSION: Flexible videoureterorrenoscopy and Holmium laser for the management of intrarenal stenosis are highly effective and safe with the advantages of less perioperative complications, less invasiveness and being an outpatient procedure compared to percutaneous surgery.

We report the case of a male patient with cutaneous metastasis of prostate adenocarcinoma located in the cervical and upper thoracic area. The patient also had a history of pulmonary tuberculosis. A CT scan revealed the presence of bone metastasis, pleural effusion, and infiltration of the soft tissues of the neck. The histopathological study confirmed the presence of cutaneous metastasis of primary prostate neoplasia. We present this case due to its unusualness and its importance in the differential diagnosis of this pathology. PMID: 31800950 [PubMed - in process]
At the RSNA 2019 conference in Chicago, Canon Medical showed off its brand new Aquilion ONE / PRISM Edition spectral CT scanner, a system that takes advantage of artificial intelligence technologies. The device relies on Canon’s Advanced int...
Authors: Loudos G, Georgiou M, Rouchota M, Papadimitroulas P, Fysikopoulos E Abstract BACKGROUND: For every new drug,>10,000 candidate molecules are tested for ~15 years. This is the daily mission of thousands research teams worldwide. It is well proven that small animal imaging speeds up this work, increases accuracy and decreases costs. However, commercial imaging systems have high purchase cost, require high service contracts, special facilities and trained staff. Thus, they are affordable to only few large research centres and not to the majority of small and medium research teams internationally. There are ...
CONCLUSION: In this material, the 18F-FDG PET/CT seems to be more accurate in terms of staging in case of the oesophageal cancer TNM classification. PMID: 31802058 [PubMed - in process]
CONCLUSION: The low agreement between amyloid PET/CT and previous clinical and instrumental assessments that we found in our study suggests that the amyloid PET/CT provides additional and early information. To perform an early and differential diagnosis of AD could have a great impact on the patient's management and cost of care in order to perform the correct therapeutic interventions and to allow family members to manage adequately the patient's demanding care.

Conclusion The dynamic second and third phase could potentially provide good predictors of clinicopathological discrimination, as can the early and delayed phases.
