Contrast-enhanced images were obtained using 600 mg/kg BW of iodinated non-ionic contrast medium (Iopamidolo Iopamiro, Bracco Imaging S.p.A.) that was injected into a cephalic vein with a power injector through an IV catheter. All studies were acquired in helical scan mode and with a slice thickness of 1 mm. General anesthesia was maintained by mechanical ventilation with isoflurane (Vetflurane Virbac, Carros, France). The dog was premedicated with an IM injection of 0.2 mg/kg/BW methadone (Synthadon ATI Bologna, Italy) and was intubated following induction with IV propofol. On the same day, a computed tomography (16-raw multidetector CT unit Aquilon, Toshiba Medical Systems Corporation, Tokyo, Japan) was performed to better visualize the TEF features. The procedure also showed a normal esophageal structure and function with a normal transit bolus speed. Fluoroscopy, however, failed to reveal the passage of contrast medium from the esophagus ventrally to the tracheal lumen. The dog was restrained in right lateral recumbency and a liquid contrast agent was administered using a catheter tipped syringe. The dog was given 15 mL of a 50:50 mixture of non-ionic iodinated contrast medium and water (Iopamidol, Gastromiro Bracco Imaging S.p.A., Milan, Italy). To further investigate the defects in the esophageal and tracheal walls, a fluoroscopic examination was performed 5 d later (Ziehm Vista Instrumentarium imaging Ziehm GMBH, Nurnberg, Germany). The BAL cultures were negative for aerobic and anaerobic bacteria.Įndoscopic visualization of the emergence of the guidewire through the esophageal opening of the TEF (arrow). In-house cytological examination revealed a neutrophilic inflammation. A bronchoalveolar lavage (BAL) of the right caudate lobe was performed with a 1 mL/kg BW bolus of sterile warm saline solution (0.9% NaCl). A round defect was noted in the tracheal wall at the tracheal bifurcation ( Figure 2A) a small amount of viscous yellow secretion along with moderate hyperemic bronchial mucosa were detected. Pulse oximetry, electrocardiogram (ECG), and blood pressure were monitored throughout the procedure. Anesthesia was maintained with propofol, a 0.3 mg/kg BW per minute constant rate infusion (CRI). Anesthesia was induced with fentanyl (Fentadon Eurovet Animal Health, Bladel, Netherlands), 2 μg/kg body weight (BW), IV, and propofol (Propovet Zoetis, Rome, Italy), 4 mg/kg BW, IV bolus. An IV catheter was placed in the cephalic vein and the dog was pre-oxygenated. The dog was anesthetized and underwent bronchoscopy with a flexible video nasal gastroscope (EG270-N5 diameter 5.9 mm Fujinon, Magione, Perugia, Italy). This also means you'll have to switch the settings back to normal when playing a day mission.Lateral thoracic radiograph showing mild broncho-interstitial pattern in the caudal lung lobes and dilatation of thoracic esophagus. ![]() Be warned, doing so will make the strait non-goggle vision worse and maybe even the NVG worse, but at night the non-goggle stuff is not as important, and there are some NVG settings adjustment mods that you can use to compensate, though most of these will turn off randomly, it seems. Until BI fixes this with the thermals or someone makes a gamma, contrast, brightness, and saturation adjustment dedicated to thermal, you'll have to mess with either your monitor(s) settings, graphic card color adjustments, or Arma 3 video adjustments, or some combination. ![]() ![]() This becomes an issue due to inadequacies of your monitor, the fact we don't see the foot or shoulder of the visual dynamic range as well as the middle, or both these issues in combination. That curve on a graph looks like kind of an S on its side, with a long middle section. ![]() What some people experience as this problem, and admittedly it affects some thermal modes/iterations worse than others, is because BI puts the limited contrast range of the thermal stuff at one end of the whole available visual dynamic range curve rather than either putting it comfortably in the middle or synthetically stretching it out.
