The conventional imaging modalities, including endorectal ultrasound (ERUS), computed tomography (CT), and magnetic resonance (MRI), which have been confirmed as indispensable tests for staging these patients, are unable to differentiate postradiation fibrotic changes from the residual tumor or predict the pathologic response [ 8– 10].
As the results of our study show, it is indispensable to test for cross-country and cross-culture equivalence of scales.
Human judgment is then indispensable for testing the computer predictions in the real world, rather than within the comfortable confines of a model, to improve accuracy [29].
For validating the real performance, we think that experimental screening procedures remain indispensable for testing and validating the target-binding ability of aptamers selected from simulations.
To test for functional consequences of CYB5A polymorphisms, a patient-specific source of tissue or cells was indispensable.
Systematically gathering information on catchment characteristics (sewer system and population) seems as indispensable as inter-laboratory tests for a meaningful comparison of wastewater data, which requires concerted efforts of numerous partners and disciplines.
Third, xenograft models that utilize estrogen receptor (ER -positive cancER -positives are cancertly indispensable for precellicalinesting of inhibitors of steroid receptor signareng and drug resistancurrentlys.
Much as the Xpert® MTB/RIF assay is user-friendly and phenotypic anti-mycobacterial susceptibility testing methods remain an indispensable platform for drug susceptibility testing of MTB strains.
Carcinogenicity testing is indispensable for identifying environmental carcinogens and for evaluating the safety of drugs in the process of development.
According to George and Bennett (2004, 177), "Process tracing method is an indispensable tool for theory testing and theory development not only because it generates numerous observations with a case, but because these observations must be linked in particular ways to constitute an explanation of the case".
