Three-Dimensional Time-of-Flight (3D TOF) Magnetic Resonance Angiography (MRA) and Contrast-Enhanced MRA of Intracranial Aneurysms Treated with Platinum Coils

Re: J Wikström et al. Three-Dimensional Time-of-Flight (3D TOF) Magnetic Resonance Angiography (MRA) and Contrast-Enhanced MRA of Intracranial Aneurysms Treated with Platinum Coils Acta Radiologica,49:2,190–196 Regrettably, there ate mistakes occurred in the appearance of Tables 2 and 3 and in Figure 3. The correct versions are shown below.
