The Pulmonary Circulation and Gas Exchange

Three-dimensional magnetic resonance imaging has several advantages over the 2-dimensional technique. It makes the visualisation of non-planar structures easier and, along with that, volume measurements; although less important for straight forward radiological diagnosis, this is very useful for treatment planning, the teaching of anatomy and notably the development of magnetic resonance angiography. Until recently though, it has generally been too complicated and time consuming to produce and present three-dimensional data for it to be of practical use. However recent advances in technology have, to some ".
