Dermatofibrosarcoma protuberans

  Clinical history: 50-year old man with progressively enlarging left upper arm mass for one year   Diagnosis: Dermatofibrosarcoma protuberans   Imaging techniques: Imaging of the left upper arm was performed on a 3T MR system (Skyra, Siemens). (A) Coronal T2-weighted TIRM (TR/TE 2734/38), (B) axial T1-weighted TSE (TR/TE 500/12ms), and (C) axial T2-weighted TSE […] [...]

Clinical Neurological Imaging on an Open Bore MRI System (MAGNETOM Espree)

An open bore MRI has the practical advantage of accommodating large or claustrophobic patients. Unfortunately, until the advent of the 1.5T MAGNETOM Espree, “open” was often synonymous with inferior image quality. However, in addition to the large 70 centimeter bore, the Espree system offers advanced coil combinations using the Total imaging matrix (Tim) and isocenter imaging technology. Together, these features allow for performance of advanced neuroimaging protocols in new clinical populations. [...]
