[Imaging tests in acute abdominal pain].

Area of Science:

• Gastroenterology
• Radiology
• Emergency Medicine

Context:

• Acute abdominal pain presents a significant diagnostic challenge due to its extensive differential diagnosis.
• Some causes of abdominal pain are serious and life-threatening, necessitating prompt and accurate diagnosis.
• The medical history is crucial for guiding the selection of appropriate diagnostic investigations.

Purpose:

• To outline the diagnostic utility of various imaging modalities for acute abdominal pain.
• To emphasize the importance of clinical history in guiding diagnostic test selection.
• To differentiate the roles of plain abdominal X-ray, ultrasound, and CT scans.

Summary:

• Plain abdominal X-rays offer limited diagnostic efficiency, primarily used when perforation, obstruction, or foreign body ingestion is suspected.
• Abdominal ultrasound is the preferred imaging test for suspected biliary tract pathology, complicated renal colic, and gynecological conditions.
• Abdominal computed axial tomography (CT) is highly sensitive and specific for most causes of abdominal pain but should be reserved for select cases.

Impact:

• Improved diagnostic accuracy for acute abdominal pain.
• Optimized utilization of imaging resources in emergency settings.
• Enhanced patient outcomes through timely and appropriate diagnosis and treatment.
