The phrase "attenuation area" is correct and usable in written English.
It can be used in contexts related to physics, telecommunications, or environmental science, where it refers to a region where signal strength or intensity decreases.
Example: "The attenuation area around the transmitter was larger than expected, affecting the overall signal quality."
Alternatives: "signal reduction zone" or "diminution region".
The low attenuation area colored in red, which meant hard materials, were corresponding to the polymer remnant in the toluidine blue images.
To investigate the incorporation of functional lung image-derived low attenuation area (LAA) based on four-dimensional computed tomography (4D-CT) into respiratory-gated intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) in treatment planning for lung cancer patients with chronic obstructive pulmonary disease (COPD).
Emphysema-predominant COPD was defined by low attenuation area at -950 Hounsfield Units (LAA-950) ≥10%.
The low attenuation area in the nephrographic phase shows relatively high attenuation (arrow).
Chest CT scan in mediastinal window setting shows multifocal lobar consolidation containing a large low attenuation area in the right lower and middle lobe, which demonstrates extension across the fissure.
Observing the previously positioned lesion marker, detecting the frame where the focal area starts forming near the marker in terms of a well-defined attenuation area; the color might start appearing light blue and become darker (Fig. 5) 8.
The special band gap property of periodic plate structure has many potential applications in wave/vibrations attenuation areas for mechanical, aerospace and civil engineering structures.
Low attenuation areas reflecting necrosis are commonly seen.
The combination of fat attenuation areas and popcorn calcifications is considered diagnostic for hamartoma on CT [9] (Fig. 2).
The diffuse form tends to be isodense to pancreas post-contrast medium administration but may show low attenuation areas centrally [44].
Large lymph nodal masses can have a heterogeneous appearance with low attenuation areas representing necrosis, haemorrhage or cystic degeneration (Fig. 1).
