Rapid Sequence MRI Analysis of Acute Abdominal Pain

Abstract

Aim: The aim of this study was to evaluate the diagnostic performance of non-contrast rapid sequences (RAMRI) visualization on cases who were clinically diagnosed as having acute abdominal pain (AAP). Materials and Methods: Forty-six patients were chosen from 2850 patients who were admitted to the emergency service between January 2016-January 2019 because of sudden onset abdominal pain and could not get a computerized tomography analysis. A 1.5 Tesla magnetic resonance (MR) device (GE Signa Hi-Speed, Milwaukee) was used for analysis. Coronal and axial T2-weighted single-shot fast spin-echo series were used as scan protocol. No intravenous, oral or rectal contrast material was used. The cases were identified as positive (+) or negative (-) by MRI. The cases who had symptoms related with AAP, were considered as positive (+), and the cases who did not have symptoms or had symptoms which were not related with AAP, were considered as negative (-). Results: Of the patients, 26 (56.5%), were female and 20 (43.5%) were male. The median age was 38.65 (18-86) years. The treatment methodology was surgery for 25 cases (54%) and conservative for 21 (46%) cases. The operative group (surgically treated) included 24 MR (+) and one MR (-) cases. There was a harmony between the clinic and MRI data of all members in non-surgical group. The accuracy of the study was calculated as 95.6% (44/46). The sensitivity of RAMRI was calculated as 96% for operative group and 100% for non-operative group. Conclusion: A successful diagnostic performance was achieved by non-contrast RAMRI in cases with AAP.

Causes of acute abdomen, preferred imaging methods, and prognoses in geriatric patients presenting to the emergency department with abdominal pain

“…Although MRI is used less frequently in the initial diagnosis 5 , today there are studies on its importance in the diagnosis of acute abdomen 12,13 . In this study, no patient underwent an MRI examination in the emergency department.…”
