Characterization of Bone and Soft Tissue Tumors at MRI
MRI protocol Optimal characterization of musculoskeletal tumors at MRI involves certain basic requirements. High-resolution, small-field-of-view axial T1-weighted spin-echo and fatsuppressed T2-weighted fast (turbo) spin-echo images should be obtained through the entire tumor. T1-weighted images are critical in showing the presence of fat or hemorrhage within a mass; distinguishing normal marro...
متن کاملMRI of Soft Tissue Tumors and Tumor Mimickers
Magnetic resonance imaging (MRI) has become a vital part of the routine work up of a patient with a suspected soft-tissue tumor of the musculoskeletal system. Unlike for bone lesions, plain radiography and CT are of little help in evaluating noncalcified tumors in soft tissue. True multiplanar capability and unparalleled capacity for softtissue contrast make MRI superbly suited to this particul...
متن کاملMetastatic Soft Tissue Tumors
Between 1998 and 2007, we treated 157 patients with malignant soft tissue tumors. Patients with obvious lymph node metastasis, metastasis from bone or soft tissue sarcoma, and with obvious advanced stage disease which had multiple metastases were excluded from the present analysis. Finally, sixteen of the 157 patients were diagnosed to have soft tissue metastasis from carcinomas or hematopoieti...
متن کاملSoft tissue tumors: Elastofibroma
The etiology of this lesion remains unclear. It seems likely that the pseudotumor mass is the product of abnormal elastogenesis rather than of degeneration of preformed fibers. It has been suggested that repeated trauma by mechanical friction of the scapula against the ribs may induce the tumorlike process, since there is an increased prevalence in persons having a history of hard manual labor....
متن کاملOncologic PET/MRI, part 2: bone tumors, soft-tissue tumors, melanoma, and lymphoma.
With integrated whole-body PET/MRI, a novel metabolic-anatomic imaging technique recently has been introduced into clinical practice. This review addresses PET/MRI of bone tumors, soft-tissue sarcoma, melanoma, and lymphoma. If PET/MRI literature is not yet available for some types of tumors, potential indications are based on available PET/CT and MRI data. PET/MRI seems to be of benefit in T-s...
