Additionally, the limits of the system have been demonstrated as a method for micro-scale visualizations and dense medium imaging.
For instance, in the case of a dense breast, further imaging modalities such as three-dimensional mammography (digital breast tomosynthesis), ultrasound or magnetic resonance imaging will help facilitate a definitive diagnosis.
Tumor spheroids are often too dense to image through directly, and requires destructive pre-imaging preparations such as cryo-section.
CT scans are good at imaging dense materials such as blood and bone, so surgeons will use them if, for example, they are concerned about bleeding in the brain, trauma or tumours that could involve bones.
Contemporary medical technology makes it possible to acquire dense data from imaging of the human body.
Ideally, such tools should have high sensitivity and specificity, as well as being noninvasive, capable of detecting microcalcifications, capable of imaging dense breast tissue, and available to a large patient population at a reasonable cost.
It may be owing to their dense connectivity that imaging changes are seen first in the thalamus and striatum, which then progress to involve other regions in a vulnerable neuronal network.
His technique extracts previously unavailable information about crustal structure and paves the way for the wider application of VDSS to Earth imaging using dense seismic arrays, or a system of seismometers deployed with dense spacing, according to SIMON KLEMPERER, a professor of geophysics and Liu's doctoral research adviser.
Due to the low sensitivity of mammography in women with dense breast tissue, other imaging modalities have been introduced in breast cancer screening including ultrasonography and magnetic resonance imaging (MRI).
Lithographic imaging produced dense lines as small as 3 μm.
