This year the Radiological Society of North America (RSNA) held its 91st annual meeting, parallel with the scientific congress and trade fair. The exhibition alone…

Dual-Source CT

X-ray computed tomography (CT) has shown an absolutely remarkable and impressive increase in its performance characteristics for many years - remarkable because the modality was declared dead in the 1980s, impressive because these developments seemed impossible to many, for technical and for physics reasons.

Radiology's leading lady

At this year's ECR in Vienna, Helen Carty, the incoming ECR 2004 president, said she felt both honoured - and rather awed - at being entrusted to lead a congress built on friendship, in which 'disparate nations of many creeds and races, rich and poor, come together to give and to share knowledge, experience and science in this nonconfrontational atmosphere'.

Robot-assisted total knee replacement

Total knee replacement (TKR) is a common procedure for treatment of severe gonarthrosis, but the outcome may be unsatisfactory due to primary malalignment of the prosthetic components. To improve precision and accuracy of this surgical procedure, CASPAR, a commercial robotic surgical system, has been adapted to assist the surgeon in preoperative planning and intraoperative execution of TKR

Its overlay-free representation of body structures and the rapid image availability make CT indispensable in the diagnostic assessment of numerous diseases, especially in emergency medicine. Modern CT systems not only offer innovative procedures for better image quality, but also reduce radiation exposure.
