This patient underwent a routine non contrast Spectral brain scan immediately after an interventional procedure to check for intracranial hemorrhage.
The monochromatic 65 keV image shows a hyperdense area.
Using Spectral analysis, the VNC image shows the hyperdense area still present indicating this area has no iodine, confirming an intracranial hemorrhage.
The iodine map fusion image and Iodine (Water) basis material image confirms the result seen in the VNC image.

Deep Learning Spectral CT Angiography of the carotid arteries. Spectral DLR enables improved assessment of lumen stenosis in the presence of calcified plaque—through improved opacification of the injected contrast with low monochromatic images, and reduced calcium blooming artifacts with high monochromatic images. The range of 101 monochromatic energy levels (35-135 keV) can be visualised in real time through an image slider, including on the PACS.
