It can be used when discussing common practices or methods that are typically shown or illustrated in a particular context.
Example: "In scientific studies, the results are usually demonstrated through various statistical analyses."
Alternatives: "are typically shown" or "are commonly illustrated".
Since the cavities are created by tissue necrosis within nodules or masses, their radiographic features are usually demonstrated as annular rings with variable wall thickness.
Myofibroblasts are usually demonstrated by the presence of alpha smooth muscle actin (SMA) expression, and their presence has also been shown to predict for disease recurrence across a number of tumour types (Surowiak et al, 2007; Tsujino et al, 2007).
In a patient presenting with suspected or confirmed liver metastasis from colorectal cancer, there are a number of questions that are frequently asked by members of this multi-disciplinary team: Focal liver lesions are not uncommon in the patient with colorectal cancer, and are usually demonstrated at staging or follow-up CT.
The safety is usually demonstrated by means of a performance assessment.
After i.v. contrast medium administration, a peripheral rim of enhancement is usually demonstrated and a central area of low attenuation may be clearly visible (Fig. 1).
The impact of soluble metal ions in aquatic and terrestrial ecotoxicological tests is usually demonstrated by comparing the effect of nanomaterials against the corresponding soluble salts [16],[16],[16].
Restricted diffusion is usually demonstrated in the projections and wall of the fungal abscess, referred to as "intracavitary projections", and represent the fungal organism itself.
The duration of DM and the degree of glycaemic control are mostly related to the development of DR. NPDR is usually demonstrated late in the first decade of the disease.
In addition to the high device performance, it is noteworthy that the deposition area of the single-crystalline organic nanoribbon arrays in this work (50 cm2) is much larger than that in the previous reports, in which a small area of lower than 10 cm2 was usually demonstrated [39].
This is usually demonstrated by using tumour response as the indicator.
This is usually demonstrated by appropriate correlations with other measures [ 4].
