Comparison of the rebuilding effects of different computed

Background: Based on the images generated from two multi-slice computed tomography (CT) scanners we intended to compare the five-line sign of normal interlobular fissures produced on axial or oblique maximum intensity projection (MIP) reconstructions using different algorithms

The diagnostic contribution of CT volumetric rendering

Such details may require the use of oblique or curved reconstructions (e g to visualize the path of a winding vessel or duct) or more complex methods such as maximum intensity projection (MIP) minimum intensity projection (MinIP) surface-shaded volume rending (SS-VRT) and virtual DOI: 10 4103/0971-3026 63043

What is MIP reconstruction?
The examination may be acquired and reconstructed at 1.0mm slice thickness - or smaller, and reconstruction intervals to allow for better characterization of small lung nodules [ 50]. Maximum intensity projection (MIP) reconstruction is a technique that may be useful to increase the sensitivity for lung nodule detection [51-55].
What is the difference between contrast-enhanced CT chest and MIP reconstruction?
Contrast-enhanced CT chest was performed on a multi-slice scanner. MIP reconstruction was performed on the workstation. The MIP images were evaluated and reported by a radiologist having more than three years of experience in reporting chest CT scans.
What is MIP imaging?
The MIP imaging technique produces a single image that is a projection of highest density of the image encountered by X-ray beam when it is traversing a stack of certain images that usually are preselected images having a variable depth [ 13 ].
Is MIP compared to CAD based on nodule size?
Overall, MIP and CAD performed similar - ly (p= 0.3563–0.0776) regardless of nodule size or CT dose protocol. MIP performance was independent of nodule composition (sol- id or ground-glass) for both standard and mi - crodose CT (p= 0.15–0.24).

Introduction
Positron emission tomography/computed tomography (PET/CT) is a widely used multimodality imaging method that provides metabolic information for oncological and non-oncological disease management (1). Steady improvements in detector design and architecture, as well as implementation of time-of-flight (TOF) and point spread function (PSF) correction ...

Discussion
Our study showed that digital PET/CT provides improved image quality and outperforms analog PET/CT, especially for MIP, sharpness, and noise with increased detectability at equal or less acquisition duration and injected activity. Up to date, only few studies evaluated in clinical practice, the differences of image quality and lesion detectability ...
Conclusion
In summary, our study demonstrated in a large cohort an improvement of image quality and lesion detectability with a digital PET/CT system. Future studies should assess the impact of these changes on clinical management.

Do MIP re-constructions improve the sensitivity of chest CT scans?

settings where CAD is not available, MIP re- constructions remain a valuable adjunct to the interpretation of chest CT scans for increasing sensitivity, with the advantage of significantly lower false-positive results.

Are MIP reconstructions a substitute for CAD systems?

satisfaction-of-search effect in phantoms con- taining two lesions, our findings suggest that MIP reconstructions might deliver similar sen - sitivities in a screening population and thus be able to serve as a substitute for CAD systems. Furthermore, MIP reconstructions are feasible without requiring more expensive CAD soft- ware solutions.

How is image reconstruction done?

Image reconstruction is done at thin slices (1.5 mm) at high-spatial-frequency algorithm which can be contiguous or overlapping. Post-processing tools including minIP and MIP to be used to assess low attenuation lesions and micronodular infiltration, respectively.
