MR bone imaging
Background/introduction Bone is highly relevant to focused ultrasound therapy, both as a potential treatment target and because it interferes with treatment of other organs such as the brain. It is challenging to image cortical bone using MRI, however, due to low water density and fast signal decay in bony tissues. Ultrashort echo time (UTE) imaging is a specialized MR technique that allows the...
متن کاملMR imaging in staging of bone tumors
For staging of bone tumors, TNM and Enneking's systems are used with some differences. Magnetic resonance imaging is particularly useful for defining the extent of high-grade tumors, including transcortical and intertrabecular infiltration and periosteal extension. The concepts of compartment and curative surgical margins are important for bone tumor staging.
متن کاملAsymmetric temporal bone pneumatization: an MR imaging pitfall.
A healthy 44-year-old woman was evaluated neurologically because she had had dizziness without vertigo and right facial pain for several months. The pain was not typical for trigeminal neuralgia, and she had had no loss of hearing. Physical examination showed no abnormalities. Cranial MR imaging was ordered for evaluation of the cerebellopontine angle. Axial MR images showed apparently normal e...
متن کاملMR Imaging Features of Extraspinal Plasmacytoma of Bone
mas, are malignant neoplasms arising from a single clone of plasma cells. They are commonly found in the axial skeleton; especially in the spine, pelvis, and skull and are characterized as expansile osteolytic bone lesions on radiography (1). The MR imaging findings of plasmacytoma or multiple myeloma located in the spine has been well described, but nonspecifically (2, 3). Plasmacytomas usuall...
متن کاملA MR imaging procedure to investigate tarsal bone mechanics
In the current work, a magnetic resonance (MR) imaging procedure to evaluate quasi-static motion of the calcaneus, cuboid, navicular, and talus is presented. It is focused on the applicability of a newly developed foot loading and positioning device. For that purpose, tarsal bone positions of three healthy subjects in a pronated and a supinated foot excursion under bodyweight were repeatedly me...
