The number of the areas with a large magnitude was 16, including eight false areas yielded by the superposition of the two signals.
An equal sized set of 'non-settlement' grid squares were randomly selected from non-settlement Africover classes to test whether the predicted settlement maps had identified false areas of settlement [13].
Do try, if at all possible, to modulate your "What, me?" response away from the strangled "Are you insane?" end of the vocal spectrum and more towards the "false modesty" area.
Patient-related factors can also lead to systemised false hypoperfusion areas, resulting for example from stenosis of the supra-aortic trunks, which produces a longer transit time between the labelling zone and the region of interest.
When QF2 < QF1, the results of the method presented in [11] and [12] contain large false alarm areas and the locations of the tampered regions are not as clearly visible, whereas our method performs better.
Otherwise, the list would be filled with two kinds of false positives: areas infiltrated with the abandoned-warehouse-turned-high-rise, where property values easily might have shot up 2,000%, but where none of these homes really appreciated, and those filled with new construction.
A threshold adjustment method based on Monte-Carlo simulations (AFNI program Alphasim) was used to guard against identifying false positive areas of activation similar to Study 1 [30].
A threshold adjustment method based on Monte-Carlo simulations as implemented in AFNI function Alphasim was used to guard against identifying false positive areas of activation [30].
Some of the "false positive" areas seen in this study were distant from the known lesion(s) (i.e. in a different lobe or even hemisphere) and may indeed represent true areas of epilepsy-related malformations, which has been reported previously in patients with CM [28].
Subtracted images should however be interpreted in conjunction with original unsubtracted images, as misregistration due to patient motion may result in false enhancement areas.
