Comparison of 1.0 M gadobutrol and 0.5 M gadopentate dimeglumine-enhanced MRI in 471 patients with known or suspected renal lesions: results of a multicenter, single-blind, interindividual, randomized clinical phase III trial.

The purpose of this phase III clinical trial was to compare two different extracellular contrast agents, 1.0 M gadobutrol and 0.5 M gadopentate dimeglumine, for magnetic resonance imaging (MRI) in patients with known or suspected focal renal lesions.

[Imaging of tumours of the adrenal gland].

For differentiation of benign and malignant adrenal lesions, sensitivities and specificities of 85-100% can be reached by unenhanced computed tomography (CT)-methods, chemical shift techniques in magnetic resonance imaging (MRI), delayed enhanced CT-techniques, and by evaluation of wash-out curves in contrast enhanced CT or MRI. An increasing number of adrenal lesions that are detected on imaging studies for indications unrelated to the adrenals can be immediately characterized by delayed series nowadays. According to excellent results of CT and MRI in characterization of adrenal masses, the indications for fine needle aspiration biopsy have already regressed as well as complications associated with this invasive technique.

[Middle field and low field magnetic resonance tomography in wrist injuries].

Purpose: To evaluate the diagnostic value of magnet resonance imaging in comparison of a dedicated 0.2-T unit and a 1.0-T unit in patients with clinically suspected scaphoid fractures and other wrist fractures.
