Angiographic imaging

Figure 4 Anti-angiogenic activity of 1 and 3. (A) Angiographic images of the developmental CAM (EDD 9) treated with 0.9% NaCl (control) and 1 and 3 (150 pM/day). The vasculature is visualized by FITC-dextran fluorescence angiography (25 mg/kg, 20 kDa, XCK = 470 nm, Xem = 520 nm).

C) The typical angiographic image (a,b) and normal coronary tree (c,d). 

Fig. 7.6a-c. Planar scintigraphy shows a focal high uptake area that could be interpreted as tumoral (a). Fusion images demonstrate that the uptake is placed outside the liver, in a vascular structure (b). A retrospective review of the angiographic images shows contrast accumulation, thus also MAA accumulation in a vascular stump located between the catheter and the coils (c)... 

Fig. 8.11. Significant embolization by SIR-Spheres leads to a rarefication of blood flow following therapy as shown in these angiographic images immediately before and after the treatment (both images were obtained with a roughly similar contrast agent flow rate)...

Until the 1990s, C-arm systems for real-time angiographic imaging used to rely on X-ray image intensi-fiers (XRIIs). Although optimized over decades, this technology has a number of inherent disadvantages that... 

Fig. 16.8a,b. Helical versus axial acquisition, a A detector with a total z-axis coverage of less than 16 cm needs to be propagated along the heart in order to cover the volume of interest for coronary angiographic imaging, b This can be achieved either conventionally with a helical acquisition as on the lefior in a stepping... 

Fig. 2.5.10a-d. Unenhanced MR images shows a colorectal metastasis in the right liver lobe (a). Angiographic imaging after chemoembolization showed a second lesion (arrow) and high lipiodol uptake in the treated lesions (b). After the third course of TACE, shrinking of the lesion could be archived (c). Contrast-enhanced MR imaging after 8 weeks shows necrosis (arrow) of the lesion (d). Nevertheless, residual tumor in the periphery cannot be excluded definitely...

The vascular information from cine PC acquisitions may be displayed as simple angiographic images (similar to cine gradient-echo images) in which all flow is bright or as phase map images in which the flow... 

Fig. 4.2.19a,b. Axial MIP (a) and coronal VR (b) CT angiographic images show a stenosis (arrows) of the hepatic artery, with periportal edema and parenchymal infarcts in the left lohe (diffuse and inhomogeneously hypodense regions)...
