Future developments in diagnostic imaging may provide improved and more specific methods of analysing skeletal lesions, including three-dimensional methods such as SPECT/CT and PET/CT.
It may be necessary to use three-dimensional methods such as pharmacophores or docking to understand why such compounds with strong similarity do not cross-react [ 17, 53, 71].
Braque rejected the spatial conventions traditionally used to create volume and depth on the two-dimensional surface, methods such as linear perspective and the classical framing devices as used in Romantic landscape compositions.
High-resolution quadrupolar spectra can be obtained with two-dimensional (2D) methods such as multiple-quantum MAS (MQMAS) [15].
Thus, three-dimensional imaging methods, such as peripheral quantitative computed tomography (pQCT), allow a selective assessment of both trabecular and cortical bone and also estimate bone strength [ 16].
Images captured by two-dimensional (2D) methods, such as radiography, provide only a projection of bone shape and do not provide a complete picture of the patient's anatomy.
An important characteristic of linear dimensionality reduction methods such as PCA is the intuitive interpretation of components in the low-dimensional space in terms of the original dimensions.
DNA nanotechnology is a rapidly progressing field owing to the ease of producing two- and three-dimensional nanostructures through methods such as DNA origami.
To obtain higher peak capacities, comprehensive two-dimensional (2D) separation methods, such as time-based (t LC × t LC, using a combination of columns) and spatial (x LC × x LC, using a flat separation bed) have been developed.
One of the major goals of three-dimensional (3D) structure prediction methods, such as comparative modeling, threading and ab initio folding, is to elucidate function from a 3D structure.
