Reliability of the talocalcaneal angle for the evaluation of hindfoot alignment
The objective of this study was to standardize the TCA measurement technique, and to evaluate the inter and intra-observer reproducibility of the proposed technique.MethodsThe foot CT scans of a group of 30 patients between 10 and 17 years of age were analysed. Ten patients had talocalcaneal coalitions, ten calcaneonavicular coalitions and ten had no coalitions. The inter and intra-observer reproducibility of the TCA was evaluated by the intraclass correlation coefficient (ICCs). A mixed-effects ANOVA model was used to calculate the ICCs for ICC2 agreement (A, 1). This procedure was applied to the three observers (inter-observer variability), and to the test–retest of observer 1 (intra-observer variability). A two-tailed p value of ≤.05 was considered significant.ResultsThe inter-observer and intra-observer agreements were excellent for the TCA. Inter-observer agreement: ICC2 (A, 1) = .95 (p
Conclusions: The results of this study demonstrate the potential of using computer-aided dynamic navigation technology in guided endodontics in clinical practice.

PandeyAbstractThe presented work aims to evaluate the effect of porosity on the corrosion behaviour of porous iron scaffold for biodegradable implant application. Two different types of iron scaffold samples were prepared using a newly developed process based on the amalgamation of 3D printing and pressureless microwave sintering. Random porous iron scaffold (RPIS) sample having only random microporous structure and topologically ordered porous iron scaffold (TOPIS) sample having designed interconnected macro...
ConclusionThe authors demonstrate that the DECT VNCa bone marrow algorithm may be helpful in identifying isodense bone lesions of various histologies and may be used to guide percutaneous bone biopsies. This technique may help to maximize diagnostic yield, minimize the number of passes into the region of concern, and prevent patients from undergoing repeat biopsy.

Schofer, Thomas J. HeyseAbstractIntroductionStudies using conventional radiographical signs and computerized tomography (CT) for retroversion of the acetabulum have reported a prevalence of up to 25%. The purpose of this study was to provide a detailed report on acetabular version, gender, age and side differences in a large cohort.Materials and methodsA total of 404 patients receiving a whole-body CT scan, aged between 16 ...
Conclusions: Hypoxic tissue is reduced following the restoration of cerebral perfusion with revascularization surgery in patients with severe atherosclerotic stenosis of the cervical ICA. The reduction in hypoxic tissue is associated with cognitive improvement in such patients.Cerebrovasc Dis 2019;47:57 –64
Conclusion 18F-FDG PET/CT cut-off values may help clinicians with their treatment planning and follow-up in locally advanced squamous cell cervical cancer patients.
Conclusion The present study concluded that 68Ga-UBI prepared using NOTA-UBI kit is a potential agent in targeting infections associated with disease conditions including diabetic foot, cellulitis and fracture. The patient selection holds significance in accurate diagnosis using 68Ga-UBI PET/CT.
Conclusion For a 18F-FDG PET/CT scan for patients with having positive myocardial 18F-FDG uptake, a respiratory-gated PET protocol divided into five phases is recommended, to minimize the influence of internal motion on cardiac accumulation.
Conclusion As the use of CT contrast fluids results in a stronger SUV increase within the liver and mediastinal blood pool than within lymphoma tissue, this may have clinical consequences regarding visual and quantitative response assessment. Ideally, CT scans for PET attenuation correction should therefore be performed in the absence of a contrast agent.
Conclusion The most common benign salivary tumour in our study was Warthin’s tumour and the majority of these patients had a primary lung carcinoma. Given that the main predisposing factor for both pathologies is smoking, potentially this suggests an association between the incidence of primary lung carcinoma and Warthin’s tumour. Ten (14%) patients in our study had a standardized uptake value of below 3.2 (using the VUE Point HD algorithm). These patients had either no identifiable lesion on ultrasound or no malignant features on histology; therefore, we propose that a cut-off of 3.2 on PET/CT could be used ...
