The correct injection of these media directly impacts whether these tests are diagnostic. CT Dual Head Pressure Injector is popular among them. Nondiagnostic results are a waste of time for the patient, the hospital workers, and the radiologist. They can also cause scheduling issues if a repeat test is required. They squander money and could subject the patient to radiation without a necessity. The worst part is that they may seriously delay therapy. Power Of The Injector: Power injectors are the only devices that can provide contrast agents at the precise timings and flow rates required to reliably produce high-quality pictures. These injectors can concurrently reduce danger when used in conjunction with gear to stop extravasation and pressure monitoring devices. However, to be successful, technologists must take into account these technologies' limits. Extravasation can occur when the jet of contrast from the injector knocks the needle out of the vein. Extravasation happens relatively seldom, and problems are often minor, but in severe situations, complications can be very bad. A manual test to see if the IV injection and the blood artery are compatible is done before the CT procedure, and the results can be used to assist avoid this from happening. This experiment may provide some subtle results. Technologists must be prepared to take action on them. Viscosity increases as concentration does. Additionally, high viscosities can result in extravasation, which, if not appropriately handled, might injure nearby tissue. Working With Machines: To ensure the safety of patients receiving a contrast-enhanced CT, people are essential while using power injectors. A non-diagnostic exam does the patient no good and only causes damage. In some circumstances, prolonged delays might be fatal. This may occur, for instance, if the CT ordered for a patient suspected of having a pulmonary embolism was non-diagnostic and the definitive diagnosis was not made for an excessively extended period. Dual-Head Injectors: Dual-head and syringeless injectors have substantially replaced single-head injectors in CT imaging. Dual-head and syringeless systems have the benefit of allowing the loading of both contrast and saline onto a single injector. Modern contrast injection systems incorporate upgrades to better handle injector protocol data, increase patient security, and streamline workflow. CT Dual Head Pressure Injector can integrate a saline flush, which guarantees complete delivery of the contrast dosage into the circulatory system and can lower the quantity of iodine required to obtain excellent imaging, in addition to providing a variety of patient safety features. Additionally, they may provide advantages including improved bolus geometry, fewer artefacts on specific CT scans, and a lower risk of contrast-induced nephropathy. A manual saline test injection is given first as part of a dual-head injection protocol to ensure that the venous access is open. This is accompanied by a power injection of a contrasting bolus and a saline chaser.   The standardisation effect is another advantage of employing a power-injected test bolus of saline. The test injections were constant with the same flow rate each time thanks to the systematic use of power injection for the test bolus as compared to manual injections, which differ from technician to technician.     http://www.medicondevices.co.in/blog/pressure-injectors-in-computed-tomography_14281.htm Wed, 15 Feb 2023 11:22:19 +0530 The watertight injector head on the CT Single Head Pressure Injector reduces damage from contrast/saline leaks and ensures secure clinical operation. An intuitive user interface, colour touch screens, automatic plunger push and pull when snapping the syringe on, and auto-detect function are further characteristics. Earlier the use of intravenous contrast media was required for many computed tomography (CT) tests to make certain organs, blood arteries, or other tissue types stand out from neighbouring structures. CT scanners used "step and shoot" technology and required lengthy scan periods up to the early 1990s. For a patient who is very out of breath and has been asked to hold their breath for 50 individual scans, it would take around 5 minutes to scan the chest, abdomen, and pelvis of an average patient with 10mm sections at 15mm centres. The radiologist performing the scan administered the initial dose of contrast by manually injecting 100 ml of contrast medium. With the contrast in the ideal circulatory phase, only a small number of images could be obtained, and there were issues with the consistency of timing and flow rates, which were very operator dependent. Modern Technology Reduces Time Slip ring technology, which was introduced, made it possible to acquire a scan as a single volume of data (using spiral or helical scanners), cutting scan times to roughly 20 seconds per body area. Nowadays, multi-detector row scanners only take a few seconds for each body region to be scanned. Nowadays, a lot of CT protocols demand multiphase scans, which involve employing a single contrast bolus to photograph a single body location at several stages of the circulatory cycle. The flow rate, volume, and timing of the injection must all be tightly controlled using new power injectors. The use of a saline bolus after the contrast has been found to have benefits in recent advancements in cardiac and angiographic CT, lowering the amount of contrast needed. CT Single Head Pressure Injectors are currently available from many manufacturers. Characteristics of CT Single Head Pressure Injector The characteristics are: ● When snapping the syringe on, an automatic plunger pushes and pulls. ● User operation trust is ensured by an intuitive user interface and a clear and crisp information display. ● The waterproof injector head design reduces damage from contrast/saline leaks and guarantees clinic operations are conducted safely. ● Bluetooth connectivity ● Separate processes for expelling and arming ensure the safety of injection. ● Warms the contrast and saline to maintain at the appropriate temperature, decreasing the negative effects on the patient. ● Reduce patient risk by displaying a real-time pressure curve and tracking pressure fluctuations. Power Injector Safety Considerations There are two key safety concerns since injections are frequently remotely initiated by the operator in the CT control room. The first entails injecting air into a vein, which could result in an air embolism in the pulmonary arteries or the cerebral circulation, which could result in a stroke. If the connecting line is not purged, there may be a few millilitres of air present, or there may be up to 100 millilitres of air if an empty syringe is accidentally used.   The second can result in damage owing to toxicity when the contrast extravasation into the surrounding tissues. This is frequently excruciatingly painful and may cause tissue breakdown.
