A description of selected MR imaging research is presented, first in terms of those developments that have already had, and will continue to have, a major influence on diagnostic radiology and then in more speculative areas.

    ABSTRACT: After an evaluation of the current situation of research in our country and establishing the concept and requisites of what is considered "quality research", this article will analyze the difficulties in carrying it out (lack of appreciation of research activity and consequent lack of necessary support and insufficient funding, lack of training for researchers, lack of continuity, among others), while trying to provide possible solutions to these problems. The important role of university hospitals will play as the backbone of translational research, coordinating research and medical practice, is also considered, together with the need to reorganize these institutions for this transcendent mission. The driving forces behind research activity in our discipline and the characteristics of radiological research are analyzed, postulating the need to return to the basics (simple, practical patient-centered research, as opposed to research based on technology) and pointing out the interest in the integration of recently constituted European organisms to promote multicenter research in medical imaging (EIBIR: European Institute for Biomedical Imaging Research).

    ABSTRACT: MR gradient systems with higher slew rates and gradient amplitude enable certain forms of imaging that are not practical with older gradient systems. These newer pulse sequences include single shot half-Fourier T2-weighted images and echo planar imaging. More important in MR imaging of the pelvis, these gradient systems benefit more conventional imaging methods such as gadolinium-enhanced 3D MR angiography, dynamic gradient echo contrast-enhanced images, and T2-weighted fast spin echo images, by shortening echo times. For most MR imaging of the pelvis, spatial resolution is paramount, and therefore sequences such as half-Fourier acquisition Turbo spin echo (HASTE) and 3D gadolinium-enhanced dynamic imaging play a less important role than in the upper abdomen. The potential of these techniques for diffusion or perfusion studies in the pelvis has not been explored.

    ABSTRACT: In this paper we describe a hardware and software environment for making available quantitative blood flow data inside and outside the magnetic resonance (MR) scanner room during MR-guided diagnostic and therapeutic interventions. The configuration allows for triggered and nontriggered examinations and provides the interventionalist with updated results within 1 second from data acquisition. The practicality of the setup and its potential for clinical and investigative purposes are demonstrated in vitro and in vivo. J. Magn. Reson. Imaging 1999;10:845–850. © 1999 Wiley-Liss, Inc.
