Native scanning is stable and fast, and a program running natively on your operating system will use the appropriate scan attributes and settings without increasing your network load".
The solution may use the best native scanning or tracking mechanism on a given device (ARKit, ARCore, Tango, Zed, Occipital, etc)., but must also store the point cloud data in a cross platform accessible database.
According to our experience, however, the performance of native scans is not necessary in the setting of renal trauma for two reasons: first, the large majority of the above-mentioned lesions are clearly recognisable also on post-contrast images; second, those lesions that might eventually be missed (i.e., small intraparenchymal or subcapsular haematomas) do not have any therapeutic consequences.
Based on the group-specific CSF, GM, and WM priors, all of the original MRI native scans were segmented.
Next, the images were smoothed with an 8-mm kernel and averaged to obtain the group-specific CSF, GM, and WM priors for later segmentation of native scans.
The threshold above the native reference scan and the delay before scanning started were 100 HU respectively 6 s for the Somatom Definition and 150 HU respective 10 s for the Somatom Definition Flash.
Today, a standard CT liver protocol typically includes an arterial and portal venous contrast-enhanced series and, when thought to be necessary, a native unenhanced scan.
Individual criteria can also require a native unenhanced scan, e.g. for the detection of calcifications and in patients with a history of transarterial chemoembolisation with iodined oil [21].
Native CAT scan missed many of these cases especially in early stage of vasospasm.
In the respective cases we performed a multiple phase contrast enhanced (CE) computed tomography (CT) including a native CT scan.
