Figure 1

Range of radio‐density representing ovine brain tissue and CSF. Normal distribution of the Hounsfield units (HU) representing the radio‐densities of ovine brain tissue (HU range of brain tissue) and those of ovine cerebrospinal fluid (HU range of CSF) (n = 72). Mean HU of brain tissue = 39.7; SD = 5.3; 99.9% confidence interval [24; 56]. Mean HU of CSF = 5.6; SD = 5.8; 99.9% confidence interval [−12; 23]. [Correction added on 04 September 2018, after first online publication: mean HU and SD values have been corrected.]
