Flat detector CT in the evaluation of brain parenchyma, intracranial vasculature, and cerebral blood volume: a pilot study in patients with acute symptoms of cerebral ischemia. Am J Neuroradiol. 2010;31(8):1462–1469. [PubMed]7. Struffert T, Deuerling-Zheng Y, Engelhorn T, et al. Drawbacks of this technique are the necessity for anaesthesia, the long investigation time and the high costs. In cases of contraindication for CMRI (CMRI-incompatible implants), the CCT can be used. Throughout the study 0.9% saline was infused at a rate of 3 ml/kg/h. BP was measured during anaesthesia.

The authors wish to thank Dr. Martin Beyerbach, Department of Biometry, Epidemiology and Information Processing, University of Veterinary Medicine, Hannover, Germany for his assistance with statistical analysis. The “ENVISION” system permits protocols that employ up to eight different phases of contrast medium infusion, wherein each phase may employ a different infusion flowrate, infusion quantity and/or infusion duration. The first slice with a visible RV lumen was identified as the apex. In the basal slice, when the pulmonary valve was visible, contours were drawn up to the junction with the valves  because the RV outflow tract should be included in the measurements. For example, an entire protocol, including short bolus, hold and remaining injection, can be stored and recalled for future use.

Thus, FIG. 3 shows that no data fields are visible in columns 214, 216 in correspondence with a fourth phase, since only three phases are being employed.

However, we welcome your feedback and encourage you to provide suggestions during this process. This is caused by the difficult definition of the RV border and especially the pulmonic and tricuspid valve.
