Quantitative and qualitative assessments of intraosseous neurovascular canals in dentate and posteriorly edentulous individuals in lateral maxillary sinus wall

Conclusion: This study reveals that dentate maxillary jaws present larger diameters as compared to posteriorly edentulous jaws, although the IA course remains the same. As these canal structures contain neurovascular bundles with diameters that may be large enough to cause clinically substantial complications, a thorough pre-surgical planning is therefore highly advisable.

Conclusion: The development of LRSS pneumatization affects the removal rate of CS tumors in PAs. Preoperative analysis of LRSS development should be considered when planning EES against PA with CS invasion. PMID: 31819816 [PubMed]

A 52-year-old woman with an asymptomatic cardiac murmur since her childhood visited our hospital. The peak pressure gradient across the pulmonary valve (PV) was calculated 25 mmHg by Doppler velocity during the transthoracic echocardiography, the severity was graded into mild. The cardiac computed tomography indicated a dome-shaped PV with an e...

AbstractPurposeTo determine imaging findings of pancreatic adenocarcinomas incidentally detected on contrast-enhanced multiphasic dynamic computed tomography (CT) obtained during the follow-up for other diseases.MethodsFrom January 2007 to December 2018, 14 patients with pancreatic adenocarcinomas incidentally detected on CT obtained during the follow-up for other diseases (incidental group) and 105 patients with pancreatic adenocarcinomas symptomatically detected on ultrasound or CT (non-incidental group) were included. Imaging characteristics of the tumor were compared between the two groups. Additionally, imaging findin...

CONCLUSIONS: HVLF and EDS produced a deep intranasal/intrasinal deposition in the silicone cast compared with conventional nasal spray delivery; both deposited liquid inside the surgically opened sinuses. HVLF offers the benefit of lavage, whereas EDS may be more efficient and convenient. PMID: 31813944 [PubMed - as supplied by publisher]

BooneAbstractX-ray Fluorescence Computed Tomography (XFCT) is an emerging imaging technique that provides elemental distribution in objects non-invasively. To predict and optimize the experimental outcome of XFCT, data generated by Monte Carlo (MC) simulation is usually used. However, MC codes typically require extended computing times to generate sufficient data. In this paper, we report an XFCT simulation method based on analytical computat...

CONCLUSIONS: The results have implications not only for understanding the stresses and strains within the ACL under different flexion angles, but also for providing preliminary data for the biomechanical and medical experts in regard of the injuries which may occur to the ACL at relatively higher flexion angles.

In this study, two TA15 titanium alloy block parts were built by HWAAM with two batches of wire. Notches on the wire surface and wire warpage aggravated the porosity of the built part. Quantitative characterization and analysis of pores were performed by X-ray computed tomography. Most of the pores were clustered at the fusion boundary. The porosity of the bead body zone was higher than that of the bead overlap zone. The equivalent diameters of pores primarily concentrated in a narrow range of variation. Spherical trapped gas pores were induced by hydrogen rejection. Irregularly shaped lack of fusion pores were caused by a...
