Aims And Objectives
- To compare MDCT findings with USG findings in patient with acute abdomen.
- To compare results of MDCT findings with operative findings / clinical outcome of patients.
Materials and Methods: Fifty patients with signs and symptoms suggestive of acute abdominal pain referred from various wards and outpatient departments were included in the study. Patients with acute abdominal pain were evaluated with both ultrasonography and computed tomography and the results were evaluated and compared.
Results: In our study Majority of cases were of pancreatitis, ureteric calculus and cholecystitis. USG diagnosis was consistent with Final diagnosis in 70% (35patients) of cases out of 50 patients. Diagnosis of MDCT was consistent with final diagnosis in 47patients with accuracy of MDCT in current study of 94%.USG findings were compared with MDCT findings and USG findings were in concordance with MDCT findings in 37 patients (74%). MDCT findings were compared with operative findings and 33 patients were operated out of 50 cases, among 33 operated cases, operative findings were similar in 28patients(84%). Pre CT diagnosis was compared with Post CT diagnosis and it was found that diagnosis was changed in 14 patients(28%) and diagnosis remained unchanged in 36cases (72%). Next Pre-CT management strategy was compared with actual Post-CT management strategy. In our study, after doing CT, management strategy was changed in 19patients (38%cases).
Conclusion: From our study, it could be concluded that MDCT is an effective imaging modality with results that have a positive effect on the management of many patients with acute abdominal pain. Radiation exposure is a drawback of MDCT but US may serve as an initial diagnostic test. CT may then be reserved for patients with non-diagnostic US results.
