Plain chest roentgenograms may be normal or show nonspecific abnormalities during the frequent febrile episodes that occur in patients after bone marrow transplantation. In this group, ultrafast 10-mm and 3-mm high-resolution CT scans were prospectively performed in 33 patients to determine if ...
High-resolution computed tomography(CT) shows focal areas of consolidation in the right upper lobe and mild bilateralemphysema(Fig. 1). High-resolutionCTafter intravenous administration ofcontrast materialand using soft tissue windows shows localized areas of low attenuation within the consolidation that ...
The scan mode uses a pitch of 3.2 to acquire a spiral CT data set of the complete thorax in less than 1 second with a temporal resolution of 75 ms (scan parameters: 128 x 0.6 mm collimation, 0.28 seconds gantry rotation time, 370 mAs at 100 kV [15 patients] and 320 mAs at 120 ...
12,31 Furthermore, a predominantly vasogenic edema tends to leave the brain tissue well preserved after resolution, as is demonstrated in HACE by the usual complete clinical recovery and normalization of MRI. Cytotoxic edema, in contrast, is generally not so benign.12 The actual mechanism of ...
High-resolution peripheral computed tomography (HR-pQCT) was developed to image bone microarchitecture in vivo at peripheral skeletal sites. Since the intr
Grating-based phase-contrast computed tomography (gbPC-CT) is a promising alternative imaging method solving the low soft tissue contrast without the need of any contrast agent. While highly sensitive measurements are possible using conventional X-ray sources the spatial resolution does often not ...

being used in this study has a total of 64 - the better the picture resolution. A computer then uses these slices to reconstruct highly detailed, 3-D images of the heart and surrounding arteries. In cardiac imaging, a patient is injected with a contrast solution to increase the visual ...
In contrast, stent lumen visibility was significantly lower for all other modes without any difference from conventional CT, suggesting that the benefits of enhanced stent visibility are primarily attributable to the resolution effect and not of other benefits of photon-counting. Similarly, using a ...
