The reconstruction result of 3B shows many inconsecutive point structures, while the reconstruction result of FID3B shows improved image continuity and is much more consistent with the real structure.
First patient images also show improved grey/white matter contrast.
This images of collagen organisation showed improved detail compared to images generated with SHG, which is currently the most effective method for viewing three-dimensional collagen organisation in tissues.
Despite these limitations, the ToBE dCTAs showed improved image quality of especially the small intracranial arteries as compared to the standard dCTAs.
In a recent study, the D-SPECT® system was compared to a conventional SPECT camera, showing improved image quality, comparable incidence of extracardiac activity, and achieving a reduction in absorbed dose to 1 mSv for a single injection [ 38].
In conclusion, this study showed that 4D dynamic CTAs derived from 320-slice CTP scans using the total bolus extraction (ToBE) method show improved image quality of the large extradural and all intradural arteries as compared to standard 4D dynamic CTAs derived using the subtraction method.
Image-derived input functions showed improved agreement with arterial measurements after a scale correction.
External beam radiation therapy combined with interstitial/intracavitary 3D-image-guided HDR-brachytherapy showed improved local tumor control relative to traditional 2D-HDR-BT with acceptable toxicity levels.
They found that the 3.0 T images showed significantly improved muscle-fat contrast, vessel-fat contrast, lymph node border delineation and total image quality, thus suggesting that this may allow more accurate detection of small positive lymph nodes.
When compared to SyN-based image registration, the SPM8 approach showed improved global results on the brain area (Figures 1 and 2).
