| description | Introduction: Hamstring avulsion injury can be defined as
improper functioning of the hamstring muscles due to external
stress or strain. The detachment of hamstring muscular region
from the tendons occurs under severe conditions. Magnetic
Resonance Imaging (MRI) is used as a diagnostic tool to study
the region of injury. Histogram analysis is a special type of image
processing technique used to describe the changes in the gray
levels of the images based on the abnormalities.
Aim: To analyse the region of Hamstring avulsion injury in MRI
slices using histogram.
Materials and Methods: Hamstring avulsion injury MRI slices
were obtained from an authorised database, Radiopeadia
for analysis. Histogram of each slice of the MRI image was
determined. Statistical features were derived from the histogram
of each slice which was used to identify specific slice of MRI with
high intensity avulsion injury. MRI slice with high intensity was
determined for further processing and analysis of the injury. For
further accurate identification of the high intensity slice in the MRI
slices, statistical features of the slice histogram were obtained.
These features were used to define the exact high intensity slice.
Results: Histograms of 10 slices of an image were compared
to obtain the slice with high intensity region. After comparison,
slice four described the high intensity which defines the affected
region of hamstring muscle. For further detailed study, statistical
values were derived from the histogram. These values were
significant for all the 10 slices but highly significant for the slice
four. Slice four was further analysed to confirm all the details
about the nature of the affected region of injury in hamstring
muscle.
Conclusion: Histogram defines the intensity variations of the
pixels which mainly illustrate the nature of abnormalities, injuries
or recognition of any region in the human body. Histogram based
statistical values were used to analyse the abnormality or injury.
These features were used in different ways for diagnosis and
analysis of various abnormalities or disorders. Thus, Histogram
and statistical features derived from the histogram from the MRI
slices of hamstring avulsion injury were compared to identify
the slice that possess high intensity region for the identification
of the injury and its characteristics. |
