Comparative study of Sensitivity of Ultrasonography and Multiple Detector Computed Tomography in diagnosing various causes of Non Traumatic Acute Abdomen

Abstract

An observational prospective study was performed on 240 patients, presenting with non traumatic acute abdomen, using USG (WIPRO P3 and GE Voluson 730 Pro) and MDCT (Siemens somatom emotion 16) . Pre-designed proforma were used to collect all the relevant information which included patient data, clinical finding, provisional clinical diagnosis, laboratory reports, USG and MDCT findings and final diagnosis following surgery/histopathologically or biochemically. The diagnosis made by USG and MDCT were compared with final diagnosis and their sensitivities in diagnosing different causes of non traumatic acute abdomen were calculated and compared with each other. MDCT proved to be a superior modality in terms of sensitivity for all patients of acute abdomen except in cases of hepatobiliary& gynaecological pathologies. In gynaecological pathologies there was not much statistical difference between sensitivities of USG and MDCT and for hepatobiliary causes USG proved to be a superior modality.
