Simpler techniques, such as MIP images can provide an overview of vascular structures, while minIP images can provide an overview of, for example, biliary obstructive changes from Klatskin tumors, or the relationship of pancreatic cystic tumors to adjacent ducts (Figures 19 and 20).
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).
Intraoperative cholangiogram, ERCP or MRCP, and MDCT images using the MinIP technique can help in the diagnosis.
Although minimum intensity projection (MinIP) and RaySum (thick MPR) have limited CTA applications, MinIP is useful for showing cardiac valves (eg, the bicuspid aortic valve), while Ray-Sum is useful for overlaying cardiovascular metallic devices with a 3D display.
Then 2-D minimum intensity projections (minIP) in the form of multiplanar reconstructions [MPR] and multiplanar volume reconstructions [MPVR] were done.
The helically acquired volumetric data is postprocessed by specially trained technologists in our dedicated 3-dimensional laboratory to generate multiplanar reconstruction images including maximum intensity projections (MIPs), minimum intensity projections (MINIPs) and curved planar reformations (CPRs).
