However, a single SUV value will be influenced by partial volume effects and many other unknown factors, causing false negative and false positive results as seen in the results of many prior studies [ 6, 7, 9, 20, 21].
The attenuation values of small hepatic cysts can be influenced by partial volume averaging, pixel size, matrix size, kilovoltage and milliamperage of the x-ray beam, slice thickness, reconstruction algorithm, patient diameter, and pseudo-enhancement.
We use a multi-planar display to define the precise post-firing position of the LCNB track, because needle visualisation by 2D within a lesion may be somewhat more subjective and be influenced by partial-volume effects towards the periphery of the lesion that might reduce the yield for small lesions.
Presumably, samples recovered from depths of 1500 to 2000 m (<15 μmol kg−1 Δ[CO3 2−]) for the calibration equation might have been influenced by partial dissolution under low Δ[CO3 2−].
One possible explanation might be that parts of the small 4 cm3 VOI was influenced by partial volume effect (PVE) in patients with thinner parenchyma rims, which was not a problem in the calibration setting.
Smaller nodules (mean volume 71 mm) in our study were more inclined to be influenced by the partial-volume effect and had lower CT density than larger nodules (mean volume 348 and 1,259 mm) in the above-mentioned studies.
Mother's thirst and hydration needs may be influenced by exclusive or partial breast-feeding [ 21, 22].
Consistent with the sensitivity of the laser stimulation in detecting thin-fiber dysfunction (Treede et al. 2003), it seems possible that the absence of LEFs in SI and PPC may be influenced by I.W.'s partial loss of Aδ-fibers.
We note that Rd(0) = Id ~ PA is related to the total amount of scattering from red blood cells in a given voxel, which may be influenced by either hematocrit, partial blood volume, or RBC orientation (which influences backscattering due to anisotropy).
The results show that bulk petroleum composition screening methods, e.g., Iatroscan[10] (saturated and aromatic hydrocarbons, resins and asphaltenes (SARA)), are likely to be influenced by contamination. Figure 1 Partial total ion chromatogram obtained during GC-MS (selected ion monitoring) analysis of the aliphatic hydrocarbons isolated from (a) core extract petroleum and (b) diesel.
Traditionally for FDG-PET imaging, SUV is obtained at some standardized single-scan time, such as one hour after injection, which will be influenced by both the actual uptake time and partial volume effects.
