[...]... Several new topics have been added, including: safety aspects of magnetic fields; fetal magnetography; new MRI techniques for cardiovascular imaging; clinical applications at ultra-high fields; interventional magnetic resonance imaging; concepts, systems, applications and new approaches in diagnostic and therapeutic MR mammography; monitoring of magnetic markers; remote-controlled drug delivery; and magnetic... electron beam tomography (EBT) In other cases – for example, that of nuclear magnetic resonance – the time taken between its discovery and subsequent application in medicine was longer Sometimes, a new method has become established in clinical practice only after having passed through a long period of in- vitro investigations and preclinical trials However, there are applications – for example, in biomagnetism... Hildanus (1560–1634), a German physician who practiced medicine in Bern, Switzerland, documented the first case of an iron splinter being extracted from a patient’s eye chamber The following is a translation of the physician’s original Latin description, titled ‘‘Of a slag splinter stuck in the cornea and its ingenious healing’’ (Hildanus, 1627): ‘ A certain farmer from the valley St Michelis, as they...
