However, single photon emission computed tomography (SPECT) imaging with the current agents is vulnerable to artifacts associated with soft tissue attenuation, proximal gastrointestinal activity, image quality, and suboptimal sensitivity and is limited by the degree of first-pass myocardial extraction.
The vulnerable small artifacts were removed from their showcases and hidden in storerooms in the basement, which was then walled up, banning any access to the lower floors.
However, it is vulnerable to artifacts – false GC-rich or AT-rich motifs frequently match TRANSFAC entries with the same nucleotide composition.
Extremely vulnerable to motion artifacts, resting state fMRI represents a decisive test for non-invasive head restraint systems.
The most important and vulnerable of the artifacts on the floor is the last column left standing from the twin towers, which is covered with graffiti spray-painted by first responders, rescuers and recovery workers.
This minimum filter step tends to lower the SNR estimate in flat areas near edges that are most vulnerable to ringing artifacts from compression.
For instance, CMOS sensors may suffer from skew on moving objects or scenes if its shutter speed is too slow, while CCD sensors are vulnerable to smearing artifacts when bright light sources overload a column or row of pixels.
A "near-universal" security breakdown was also blamed, leaving the artifacts vulnerable to theft.
Furthermore, some brain regions, especially the MTL, are difficult to assess using echo-planar imaging (EPI) because they are highly vulnerable to susceptibility artifacts [73].
However, slower acquisitions potentially make IV-OCT imaging more vulnerable to motion artifacts (e.g., cardiac motion) [ 5].
