Abstract:
Cristal deposit disorders are characterised by cristal deposits in hyaline and fibrocartilage, in synovium, capsule, ligaments and tendons and periarticular soft tissue. Calciumpyrophosphatedihydrate (CPPD), hydroxyapatite (calcific tendinitis) and uric acid arthropathies are the most common cristal deposit diseases. Radiography is still the number one image modality for initial imaging and the identification of cristal-induced inflammatory arthropathies. Differentiation between the entities of cristal deposit arthropathies can be challenging. Clincial and radiological findings may overlap in different cristal deposit arthropathies, owing a certain diagnosis difficult.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
