Sentence examples for attenuation density from inspiring English sources

Gamma-ray attenuation density.

One group has measured a transmural perfusion ratio during adenosine stress CT (subendocardial attenuation density/subepicardial attenuation density) to detect myocardial perfusion abnormalities with a sensitivity/specificity of 86%/92% on a per-patient analysis [33].

The age model is further tuned to LR04 δ18O curve using gamma ray attenuation density (GRA) since it reflects diatom contents that are higher during interglacial high-stands.

The radiological diagnosis of acute IS included brain computed tomography; that is, a new finding of low attenuation density in the focal or diffuse brain area.

Computed tomography (CT) can show areas of reduced attenuation density at the level of the periaqueductal grey matter and the medial portion of the thalami but, in most cases, is negative in the acute phase of WE [ 3, 58].

Pathological diagnosis significantly affected the frontal but not temporal lobe myelin attenuation: myelin density was most reduced in VaD compared to AD and DLB, which still significantly exhibited lower myelin density compared to ageing controls.

In particular, both ocean and sediment sound speeds were randomized, the sediment attenuation and density were randomized, and the depth of the ocean/sediment interface was randomized.

Splicing is usually performed onboard using physical properties such as magnetic susceptibility (MS), gamma-ray attenuation (GRA) density, natural gamma-ray radiation (NGR), and the lightness and color of sediments measured immediately after drilling.

After scanning the phantoms, the "ratio value" (R-value) was defined as the ratio of the low to high energy attenuation for density and thickness.

In that study, the analysis of the pulmonary morphology was performed by a technique involving measurement of the CT attenuation (pulmonary density) using a fast spiral scanner.

Finally, although our study raises concerns about the use of high attenuation lung density thresholds alone for the classification of ILA, our study does not exclude the possibility that measures of increased lung density could provide additive clinical information.
