Application of diffusion weighted Magnetic Resonance Imaging (MRI) of the brain at the Kenyatta National Hospital
Abstract
Aim: To demonstrate the spectrum of findings (intensities) at Diffusion
Weighted Imaging (DWI) of different brain pathology using the l.5T
PhillipsIntera MRIscanner.
Method: This was a Hospital based prospective study at Kenyatta
National Hospital (KNH) at the Radiology Department using
questionnaires, and MRI images. A random sampling was applied to
get the patients who underwent brain scan and had a diagnosis as per
theclinical and MRIfindings.
The signal intensities of brain lesions on diffusion Weighted Imaging
were documented. The intensity of the lesion was also described on
other sequences e.g. TIW, T2W, FlAIR, e.t.c. The diagnosis was made
from both the history and the MRI appearances of the lesions.
The data collected from the patients/MRI records was entered in a
Microsoft access database and exported to a specialised statistical
package for analysis with an assistance of a Bio-statistician.
Results:
The results are presented in summarised tables; graphs and form the
platform for the conclusion and recommendations. Among the lesions
described are infarcts, tumours, demyelinating disorders and infective
processes. This is further described in the methodology.
