Surgeons call on HoloLens during reconstructive surgery
In a recent case study published in European Radiology Experimental, surgeons at St. Mary’s Hospital in London used Microsoft HoloLens to overlay images of CT scans onto patients'legs during reconstructive lower limb surgery.
Conclusions: Proper clinical conditions, for scheduling a postextraction immediate implant placement surgery, involve the presence of 4 bone walls showing and sufficient height and width. The accurate knowledge of alveolus bone morphology of mandibular molars, prior extraction, could be an important guide to avoid potential failures due to nonideal anatomical features to fixture stabilization.
This study is the first to demonstrate the feasibility of producing high quality microcapsules from labile flavor complexes by spray-chilling. The use of generally recognized as safe (GRAS) substances, including 2AP and ZnCl2, may allow for widespread commercial use of 2AP as a flavor ingredient.

Organic cross-linked polymer gel such as cross-linked polyacrylamide gel is one of the most popular and available gel sealant materials. It is of strong sealing ability, but the gelation time is too short to control and ensure safe drilling operation. Initiator used to supply free r...
CONCLUSIONS: Using FBP, comparable IAC measurements were achieved with 91% reduction in dose compared with a standard exposure protocol. The use of ASIR and MBIR did not improve identification of the IAC in MDCT low dose images. PMID: 29791199 [PubMed - as supplied by publisher]
Iodinated contrast agents administered during computed tomography (CT) studies have the potential to cause post-contrast acute kidney injury (AKI). Prior to CT scans, in certain populations, assessment of the estimated glomerular filtration rate (eGFR) is required to identify patients at risk for adverse events after contrast administration.
Authors: Schmidt W, LiArno S, Khlopas A, Petersik A, Mont MA Abstract Due to the differences in bone morphology between demographics such as age, gender, body mass index, and ethnicity, the development of orthopaedic implants requires a large number of anatomical data from various patient populations. In an effort to assess these demographic variations, Stryker Orthopaedic Modeling and Analytics (SOMA) has been developed. SOMA is a suite of tools which utilizes a comprehensive database of computed tomography scans (CT-scans), plus associated three-dimensional (3D) bone models, allowing the user to assess population...
Abstract Bochdalek hernia (BH) is defined as herniated abdominal contents appearing throughout the posterolateral segment of the diaphragm. It is usually observed during the prenatal or newborn period. Here, we report a case of an adult patient with herniated omentum and colon due to BH that was discovered during a colonoscopy. A 41-year-old woman was referred to our hospital with severe left chest and abdominal pain that began during a colonoscopy. Her chest radiography showed colonic shadow filling in the lower half of the left thoracic cavity. A computed tomography scan revealed an approximately 6-cm-sized left...
The aim of this systematic review is to investigate diagnostic accuracy of Magnetic Resonance Imaging (MRI) scans using liver specific tissue contrast media over contrast enhanced Multi Detector CT (MDCT) in diagnoses of Hepatocellular Carcinoma (HCC) in patients with chronic liver disease.
A 14-year-old boy presented with intermittent hematochezia for 2 weeks. He reported a similar episode of hematochezia 1 year ago that was regarded as colitis. His medical history was unremarkable. Physical examination showed a nontender, soft, palpable mass at the upper right quadrant of the abdomen. His hemoglobin level was 7.3 g/dL (normal range, 13.0–16.0 g/dL). A computed tomography scan of his abdomen showed asymmetric segmental wall thickening with scattered punctuate calcification (Figure A, white arrow) and heterogeneous enhancement from the m idtransverse colon to the hepatic flexure (Figure A, black arrow).
Conclusion Binimetinib may present a new treatment option for hormone- and chemotherapy-resistant LGSOC harboring KRAS mutations.
