Measurements of Normal Lateral Ventricles in Adult Sudanese Patients Using Computed Tomography

Abstract

The lateral ventricles can be measured using Computed Tomography, we can measure the length , the width and the density of CSF .This study was carried out using CT machines in Khartoum teaching hospital and some clinical private centers, from June 2009 to December 2009. The main objective of the study is to measure the normal lateral ventricles in Sudanese patients. Seventy five Sudanese adult patients ( 35males (46.7%), 40 females (53.3%)) with different ethnic groups, 44 patients from Northern and Center of Sudan (58.7%), 3 patients from Eastern of Sudan (4%), 25 patients from Western of Sudan (33.3%), and 3 patients from Southern of Sudan (4%). the age group are ranged between (20-50) years .The patients were free from any brain diseases that affect the measurement of lateral ventricles. The patients were examined by computerized tomography using CT spiral unit, dual slices, siemens (Somatom Emotion TUO), CT spiral unit, sixteen slices, siemens and CT spiral unit, dual slices, shimadzu with the known CT protocols for brain. The measured parameters by CT include the width of lateral ventricles (Rt , Lt) at maximum posterior horn, the two hemispheres at maximum brain diameter (MBD), the level of the body of lateral ventricles (Rt, Lt) and the density of CSF which has been determined by the CT number of the fluid. Certain other variables were considered like, age, gender, tribe, body weight and the height. The analysis shows that the mean of width of right and left lateral ventricles (at maximum posterior horn), Level of the body of right and left lateral ventricles, CT- No. of cerebrospinal fluid were 1.0 ± 0.2 , 1.0 ± 0.2 , 1.1 ± 0.3 , 1.1 ± 0.3 , 9.4 ± 2.8 respectively .

The correlation between the age and all parameters (the width of right and left lateral ventricles (at maximum posterior horn), the level of the body of right and left lateral ventricles and CT- No. of CSF were insignificant giving the values of 0.8 , 0.8 , 0.8 , 0.5 and 0.2 respectively. The correlation between weight and all parameters (the width of right and left lateral ventricles (at maximum posterior horn), the level of the body of right and left lateral ventricles and CT- No. of CSF were insignificant giving the values of 0.3 , 0.6 , 0.5 , 0.08 and 0.5 respectively. The correlation between the height and the width of right and left lateral ventricles (at maximum posterior horn) were significant giving the values of 0.033, 0.022 respectively, but the correlation between the height versus the level of the body of right and left lateral ventricles and CT- No. of CSF were so insignificant giving the values of 0.9, 0.9 and 0.1 respectively. The correlation between the gender and the width of right and left lateral ventricles (at maximum posterior horn), level of the body of right and left lateral ventricles, CT- No. of CSF were insignificant giving the values of 0.6 ,0.6 ,0.9 , 0.5 and 0.1 respectively. The correlation between the tribe and the width of right and left lateral ventricles (at maximum posterior horn), level of the body of right and left lateral ventricles, CT- No. of CSF were insignificant giving the values of 0.2 ,0.4 ,0.4 ,0.3 and 0.7 respectively . The correlation between the width of right lateral ventricles (at maximum posterior horn), and left lateral ventricles (at maximum posterior horn) was significant giving the values of 0.0, 0.0 respectively. The correlation between the level of the body of right lateral ventricles and the level of the body of left lateral ventricles was significant giving the values of 0.0, 0.0 respectively The correlation between the ratio VR/HR and (age, weight, height ,gender) were insignificant giving the values of 0.6, 0.5, 0.1 and 0.8 respectively. The correlation between the ratio VL/HL and (age, weight, height, gender) were insignificant giving the values of 0.9, 0.9, 0.1 and 0.8 respectively.
