Allsubjects(407patients)diagnosedashavinglowback painwereclassifiedinto3 groups:

GroupA             Normal(108)patients

GroupB             ObeseI (113)patients

GroupC               ObeseII(186)patients

VBMI groups classified in total 407 patients are as follows:

Radiological  Findings

Among 407cases,19casesarenormal,376casesarefoundas DiscDiseasesand another12 casesarefoundas incidentalfindings. Indiscdiseasescases,PID wasthemost commoncases.

Findingswhich are related with discs and spinal pathology

CONCLUSION

• According to our case study, degenerative discs disease is the most common cause especially Prolapsed Intervertebral Disc(PID).

• In addition, we can find out the incidental findings such as lower pelvis mass  and ovarian cyst. That’s why we want to suggest all the  female patients who has suffering back pain because MRI has no radiation hazards.

• Moreover, sports and daily exercises will be helpful to maintain BMI within normal range.
