NAEOTOM Alpha VA50 Update Training - Cardiovascular Imaging Video

Welcome to the new atom. Alpha software. V A50 update training for the new features of cardiovascular imaging. Coming up in this training, we will cover the. New cardiovascular. Imaging features in VA 50. The first new feature is a scan mode called. Flash phase spiral? Flash phase. Spiral enables an ECG triggered high pitch flash scan mode which allows for an independent control of the Z position of the ECG target phase within the scan range. This enables for example. A high. Pitch skin over the entire thorax while separately specifying the cardiac starch phase at 65% at the beginning of the heart. Protocols. That have this new scan mode include. Thorax coronary CTA with the quantum plus scan modes. Thorax, coronary, CTA alternative with quantum scan modes. Tabby with the quantum plus scan modes. Tavie alternative with quantum scan modes. With. Flash face. Spiral. You can freely adjust the beginning of the phase start using the line in the topography. Do this by simply dragging the line to the desired location where the selected phase should start. In the ECG display you can see where the line in the top program the selected start. Phase corresponds. In the actual scan range. In the scan parameters under the Physio Scan tab. The phase START option corresponds to the position of the line in the top program. The flash scan will be timed automatically to scan with the. Phase start where you. Have positioned the line in the topography. By changing the phase start to a diastolic range, the scan range and timing shift automatically. This is to ensure that the timing will be correct with where you have positioned the line and selected the phase start. The next new feature is the pure calcium reconstruction. Pure calcium is a. Spectral reconstruction, that. You can produce from a cardiac angio examination for which you injected contrast medium. A pure calcium reconstruction can then be used to perform a calcium score. Thanks to the spectral information contained in the data set, iodine can be virtually removed and any calcium. Will be left in the images for. Scoring purposes. You can use the resulting virtual non iodine images or called vni in a conventional calcium scoring method. Since this is a spectral reconstruction, it is only available with the quantum plus scan modes. With pure calcium, you need to use a monoenergetic plus 70 Kev reconstruction to ensure the proper density in the calcium. Use the kernel QR 36 since this is a spectral reconstruction. All other Recon parameters should match a traditional noncontrast calcium scoring reconstruction. For instance, A3 millimeter slice thickness and field of view size. The automatic calcium scoring application with inline results is not currently available to use with a pure calcium reconstruction. However, when you select auto tasking and local application, you can assign CPT calcium scoring to the Recon. This will automatically load this series into the calcium score application and you can then score it manually. In March 2022, a study was published in investigative radiology showing a significant improvement of pure calcium over virtual noncontrast images in calcium scoring when compared to true NONCONTRAST exams. The title of. This paper is. Coronary computed tomography angiography based calcium scoring in vitro and in vivo validation of a novel virtual non iodine reconstruction algorithm on a clinical first generation dual source photon counting detector system. Recon and go inline results, vessel specific calcium scoring. This fully automatic scoring algorithm breaks down the total calcium score to the individual coronary branches, such as the right coronary artery, left main, left anterior, descending, and circumflex. New protocols for cardiac scanning in VA 50 include. The coronary CTA stent protocols. These protocols have the high res ultra scan mode and will utilize the uhr collimation of 120 by 0.2 millimeters. With ECG. Triggering. Again, there is a routine protocol with quantum plus scan modes. As well as the alternative protocols with the quantum scan modes. It is important to keep in mind that these protocols will have longer scan times due to the smaller collimation. With this scan sequence and spiral modes. Are available, but no. Flash mode is possible. Also. There are tube limitations in maximum tube current due to a smaller focal spot size. This means that this protocol is not recommended for obese patients. The reconstructions. In this new protocol. Have no spectral. Information available. All images are. At. 3D reconstruction. However. The benefits? Are that the cardiac reconstructions can have high resolutions with slice thicknesses down to a 0.2 millimeters and kernel sharpness up to a 98. A study. Performed from the University Hospital of Zurich that is published in. Investigative radiology. Gives guidance on parameters. For cardiac UHR. You may refer to this paper. For proper scan and reconstruction parameters to. Use for optimal results. The title. Of this. Paper is. Ultra high. Resolution coronary CT angiography with photon counting detector CT. Lastly, new in V A50 is the ECG documentation option. In the reconstruction parameters under the Physio Recon tab. You can. Toggle on or off. The ECG. Documentation per. Individual reconstruction job. Now you can limit how many ECG. Series the scanner produces. Per examination.
