Plain Magnetic Resonance (MR) in the Assessment of Patients With Acute Abdomen
Plain Magnetic Resonance (MR) in the Assessment of Patients With Acute Abdomen
At present, CT is the gold standard in the assessment of patients with acute abdomen. Yet,
 one CT of the abdomen exposes patients to a radiation dose equivalent to several years of
 background radiation. MR can be expected to yield the same information without ionizing
 radiation, but tends to be more time consuming. In this study, patients with nontraumatic
 acute abdominal pain referred to CT of the abdomen by the department of surgery will also
 have performed an additional MR scan covering the entire abdomen with few fast imaging
 sequences in approximately 15min. CT is the diagnostic test. The MR scan is only used for
 scientific purposes. It will be evaluated by a radiologist blinded for the results of the CT
 scan. Fourteen days after admission, a final diagnosis is established based on clinical,
 peroperative, pathological and lab. findings. The performance of CT and MR will then be
 compared. The investigators hypothesize that MR can provide a diagnostic accuracy comparable
 to CT.
