Optimal contrast dosage in cranial computed tomography

Comparison of different contrast dosages in adult patients with malignant gliomas studied by computed tomography indicates that 28-42 g of iodine is required for clinically diagnostic results. This can be translated into a 10 min iodine blood level of 100 mg/100 ml. Contrast doses in the range of 14 g of iodine are not satisfactory.
