What is a CT Scan? A machine whirs in an arc around a patient, snapping a rapid-fire series of x-rays from different angles. These x-ray snapshots are combined by a computer to produce virtual cross-section images of the body. These are called CT scans, which stands for computed tomography (computer-generated cross-sectional images). CT Scans Compared to Ultrasounds and MRIs When the CT scan was first introduced in the 1970s it caused something of a revolution in medicine, allowing doctors to see the inner structure of the body in a way that had been previously hidden – without surgery. Parents often wonder which is ...

This study has terrific significance and could be extremely important,” Harbut, clinical professor of internal medicine at Wayne State University and Michigan State University, told The Mesothelioma Center at Asbestos.com. “We’re going after this one with great guns.” The study is part of a new partnership between Owlstone Medical — the Breath Biopsy inventor in the United Kingdom — and the International Association of Heat and Frost Insulators and Allied Workers, a building trade union that covers the United States and Canada. Early Diagnosis Still a Rarity The first part of the study ...

We report the case of a 19-year old man who presented to our institution with a history of pain of one week in the ulnar side of the left wrist and continuous pressing sensation in the palm. According to patient, there was no history of acute hand trauma. The conventional roentgenograms did not show the fracture and computerized tomographic (CT) scanning demonstrated a complete fracture of the hook of the hamate. The patient was given a surgical intervention and the hamate bone was reduced through a palmar skin incision. After surgery, the operated hand was immobilized in a wrist brace and the patient was put on a rehabili...

In this study, we aim to determine significant impact on radiation dose as a result of mis-centering during CT head examination. The scanning was performed by using Toshiba Aquilion 64 slices multi-detector CT (MDCT) scanner and dose were measured by using calibrated ionization chamber. Two scanning protocols of routine CT head; 120 kVp/ 180 mAs and 100 kVp/ 142 mAs were used represent standard and low dose, respectively. As reference measurement, the dose was first measured on standard cylindrical polymethyl methacrylate (PMMA) phantom that positioned at 104 cm from the floor (reference isocenter). The positions then we...

FinnertyAbstractPhysiological conditions can alter the performance of electrochemical sensors through complex interactions arising at the tissue matrix and electrode interface. Understanding this relationship is a prerequisite to the eventual deployment of these sensors in vivo. Herein, we investigate the ability of energy dispersive X-ray (EDX) analysis to monitor silicone oil levels within carbon paste electrodes (CPE). We correlate these findings with scanning electron mic...

CONCLUSIONS: The new proposed approach yielded good performance on spectral CT material decomposition, which could establish guidelines for multi-material decomposition approaches based on the deep learning algorithm. PMID: 31177260 [PubMed - as supplied by publisher]

ConclusionThis is the first case in the literature to describe a post-laminectomy pseudarthrosis leading to a significant sagittal malalignment in a patient with ochronotic spondyloarthropathy. Management of such a case is challenging as the spine is partially ankylosed; therefore, a long construct is advisable to avoid ankylosing disorders related complications.

Publication date: Available online 3 June 2019Source: PolymerAuthor(s): Arnold Wilbers, Ander Biguri, Jennifer Schillings, Joachim LoosAbstractIn general, fiber reinforced polymer materials are being used in case of challenging mechanical requirements. Important parameters determining performance of such polymer composites are properties of the components as well as the quality of the fiber-polymer interface. For example, porosity or voids particularly at the interface will influence the overall performance of the composite negatively. Therefore, it is of importance to know the actual porosity value to e.g. calculate and p...

The first attempts to calculate the diffraction efficiencies of gratings in the soft X-ray range were made on a scalar model. The results were simple analytical equations, that always severely overestimated the performance of real objects. In this respect, computer programs were found to be more successful, which rigorously consider all diffracted and refracted waves. Consequently soft X-ray gratings are presently optimized using these tools, which requires rather extensive calculations for any instrument optimization as general trends are not immediately obvious. Here it will be shown that the results of the rigorous calc...

Yesterday I went to the hospital to see an orthopedic surgeon who told me to use my left hand as much as possible from now on, so this morning I thought I’d give typing with two hands a try, even though my arm is still in a sling, of course, and I’m not supposed to move my left shoulder at all. Yep, yep, yep, this works…for a short post, anyway… The orthopedist told me that my fracture is borderline for surgery. I’d actually been told the same thing last Monday, so I knew surgery might be in the picture. Aggghhhh!!! For a moment, yesterday, I froze… When I told her about my smoldering...
