The role of MR imaging in the evaluation of children with large, deep, or infiltrative soft tissue masses is to characterize and determine the extent of the lesion for treatment planning. There are a small number of soft tissue tumors with MR imaging appearances characteristic enough to allow a specific diagnosis, obviating biopsy. In the remaining cases with nonspecific imaging appearances, MR imaging is used for anatomic staging, but tissue sampling is still required for determining histology and grading.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D009140	Musculoskeletal Diseases	Diseases of the muscles and their associated ligaments and other connective tissue and of the bones and cartilage viewed collectively.	Orthopedic Disorders,Musculoskeletal Disease,Orthopedic Disorder
D009221	Myositis Ossificans	A disease characterized by bony deposits or the ossification of muscle tissue.	Fibrodysplasia Ossificans Progressiva,Myositis Ossificans Progressiva,Progressive Myositis Ossificans,Progressive Ossifying Myositis
D009455	Neurofibroma	A moderately firm, benign, encapsulated tumor resulting from proliferation of SCHWANN CELLS and FIBROBLASTS that includes portions of nerve fibers. The tumors usually develop along peripheral or cranial nerves and are a central feature of NEUROFIBROMATOSIS 1, where they may occur intracranially or involve spinal roots. Pathologic features include fusiform enlargement of the involved nerve. Microscopic examination reveals a disorganized and loose cellular pattern with elongated nuclei intermixed with fibrous strands. (From Adams et al., Principles of Neurology, 6th ed, p1016)	Neurofibromas
D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
D002675	Child, Preschool	A child between the ages of 2 and 5.	Children, Preschool,Preschool Child,Preschool Children
D003560	Cysts	Any fluid-filled closed cavity or sac that is lined by an EPITHELIUM. Cysts can be of normal, abnormal, non-neoplastic, or neoplastic tissues.	Cyst
D005218	Fat Necrosis	A condition in which the death of adipose tissue results in neutral fats being split into fatty acids and glycerol.	Steatonecrosis,Fat Necroses,Necrosis, Fat,Steatonecroses
