Cerebral Magnetic Resonance Spectroscopy at 1.5T and 3T

MR spectroscopy is a powerful technique that adds metabolic information to routine MRI brain examinations. Through four cases, this article provides tips for performing cerebral MRS. Examples of additional information using this technique include differentiating cerebral neoplasms from abscesses and distinguishing solitary primary cerebral neoplasms from solitary cerebral metastatic deposits. [...]

Assessment of Tumor Extension and Improved Localization for Planning and Nerve Sparing Radical Prostatectomy

The potential of state-of-the-art MRI at 3 T, in prostate imaging without the use of an endorectal coil, is discussed in this article. Two clinical cases are presented, with MRI in each instance able to improve both therapy planning and surgical outcome. [...]

Comprehensive MRI-Based Staging of Rectal Cancer. Beneficial Combination of Local High- Resolution Imaging and a Moving-Table Platform for Simultaneous Detection of Metastasis

The evolution of sophisticated surgical repair procedures for the treatment of isolated, focal traumatic or degenerative cartialge lesions has created the need for accurate, non-invasive assessment of the repair tissue. MRI depicts well subchondral bone and bone marrow, allowing examination of repair tissue and its interface with parent cartilage and complications of repair surgeries such as graft hypertrophy and delamination.
