dki

DKI is an acronym that can refer to multiple concepts, depending on the context. This article outlines two principal uses: a political-geographical entity in Indonesia and a medical imaging technique.

DKI Jakarta refers to the Special Capital Region of Jakarta, abbreviated as DKI in Indonesian for Daerah Khusus Ibukota Jakarta. It serves as the capital and seat of government of Indonesia. The region is coextensive with the city of Jakarta and has its own provincial-level administration, headed by a governor and a regional council. It comprises five administrative cities—Central Jakarta (Jakarta Pusat), North Jakarta (Jakarta Utara), South Jakarta (Jakarta Selatan), East Jakarta (Jakarta Timur), and West Jakarta (Jakarta Barat)—and one administrative regency, Kepulauan Seribu (the Thousand Islands). As the nation’s capital, DKI Jakarta is a central hub for government, commerce, culture, and international activity, with high population density and substantial economic output.

In medical imaging, DKI stands for Diffusion Kurtosis Imaging. This diffusion MRI technique extends conventional diffusion tensor imaging by modeling non-Gaussian water diffusion, providing a more detailed view of tissue microstructure. DKI uses diffusion data acquired with multiple b-values and yields metrics such as mean kurtosis, axial kurtosis, and radial kurtosis. It can improve sensitivity to microstructural changes in white matter, gray matter, and tumors, but typically requires longer scan times and careful motion management.

Because DKI has multiple legitimate meanings, the intended interpretation depends on the surrounding text and discipline.
