To complicate matters further, these diagnostic modalities are difficult to obtain in most centers 24 h a day [1].
However, these modalities are difficult to perform on the patient with AAD due to the immense pain associated with this condition.
Viability is limited, so long term effects of treatment modalities are difficult to assess.
For most physicians, selecting the appropriate diagnostic modality is difficult.
In contrast to predation intensity, measuring, characterizing and comparing modality is difficult, even more so without clear categories and definitions.
Furthermore, categorizing each case specifically based upon the type of uterus preserving treatment modality is difficult since there are varying degrees of placental attachment abnormalities and varying amounts of the placenta which adhere abnormally to the uterus.
The Impulsion modality was difficult (high rates of failure) and the speed-accuracy trade-offs predicted by Fitts' law were absent (bow-shaped patterns as function of target amplitude instead of logarithmic increase).
In this study, the evaporative method was combined with conductive techniques, namely cooling blanket, gastric, colonic and bladder lavage with iced saline, and intravenous administration of chilled solutions; thus the relative contribution of each modality was difficult to assess.
However, due to the intrinsic limitations of some imaging modalities, it is difficult to accurately reconstruct catheters.
