Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [ 1 ] [ 2 ] It also contains the stromal vascular fraction ( SVF ) of cells including preadipocytes , fibroblasts , vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages .
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [ 1 ]
[8] [9] The variation of body fat distribution resulting from normal growth is influenced by nutritional and hormonal status dependent on intrinsic differences in cells found in each adipose depot. [10] Mesenchymal stem cells can differentiate into adipocytes, connective tissue, muscle or bone. [1]
Brain positron emission tomography is a form of positron emission tomography (PET) that is used to measure brain metabolism and the distribution of exogenous radiolabeled chemical agents throughout the brain. PET measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream.
It consists mainly of loose areolar and fatty adipose connective tissue and is the layer that primarily determines the shape of a body. [medical citation needed] In addition to its subcutaneous presence, superficial fascia surrounds organs, glands and neurovascular bundles, and fills otherwise empty space at many other locations.
To better visualize the anatomy, post-processing of the images is common. [54] Most common are multiplanar reconstructions (MPR) and volume rendering. For more complex anatomies and procedures, such as heart valve interventions, a true 3D reconstruction or a 3D print is created based on these CT images to gain a deeper understanding. [62] [63 ...

Whole-body PET scan using 18 F-FDG (fluorodeoxyglucose). The normal brain and kidneys are labeled, and radioactive urine from breakdown of the FDG is seen in the bladder. In addition, a large metastatic tumor mass from colon cancer is seen in the liver. PET scanning with the radiotracer [18 F]fluorodeoxyglucose (FDG) is widely used in clinical ...
