Introduction
CT is the primary imaging modality for many causes of acute abdominal pain and trauma due to its speed sensitivity and anatomic detail. Protocols include noncontrast and contrast enhanced phases tailored to suspected pathology. Rapid interpretation and communication with clinical teams are critical for timely management.
Acquisition and Phases
Portal venous phase imaging is commonly used for general abdominal evaluation while arterial phase is added for suspected vascular injury or active bleeding. Noncontrast scans are important for stone detection and hemorrhage assessment. Thin slice reconstruction and multiplanar reformats aid surgical planning.
Trauma and Workflow
Whole body trauma pan scans include head neck chest abdomen and pelvis to identify life threatening injuries in polytrauma patients. Coordination with trauma teams and standardized reporting templates expedite decision making. Radiation dose optimization remains important even in emergent settings.
Follow Up and Communication
Clear documentation of findings and recommended next steps supports clinical management and surgical planning. Repeat imaging decisions should balance clinical change and radiation exposure. Multidisciplinary review improves outcomes for complex cases.
