VR, MIP, MinIP and Ray-Sum are applied to convey fetal spatial detail and structural relationships (Figures 5 and 6).
RaySum, MinIP and VR techniques can be applied to determine fetal position.
MinIP images can also depict the lumina of the airways.
For example, spindle cell sarcoma mediastinal invasion with near complete occlusion of the left main stem bronchus is better depicted by curved reformatted, oblique, coronal, MinIP and 3-dimensional VR images, compared with the acquired axial images (Figure 3).
These reconstructions provide better anatomic definition of key structures commonly affected by locally invasive pancreatic neoplasms (Figure 7), including thin-slab MIPs of the celiac origin, portal and splenic veins; CPRs of the superior mesenteric vein and artery, hepatic artery, gastroduodenal artery, splenic artery, distal common bile duct and pancreatic ducts; thin-slab MINIPs
of the pancreatic ducts; and, coronal MPRs in the plane of the main portal vein through the entirety ofthepancreas.
