Disease diagnostics and molecular imaging are challenging subjects to pharmacologists and drug delivery scientists. The advent of nanotechnology and imaging techniques has helped us to understand the disease prognosis and yielding an efficient treatment. Imaging techniques have been a significantly improving science. A combination of nanotechnology and imaging improved the specificity, accuracy, and sensitivity for molecular imaging. Moreover, such combination is being applied in diagnosis and treatment of cancer or heart and brain diseases. For example, iron oxide nanoparticles and MRI. To improve selectivity, targeted nanocarriers with imaging techniques have been investigated. These techniques may be used to load therapeutic agents that can improve diagnosis and treatment of ailments. In the near future, such combination of technologies may lead to better, selective, and sensitive treatment modalities.
