Rationale of imaging Clinical data of the patient. ERCP/MRCP Biliary colic Ultrasound Epigastric pain with high serum amylase CT Flank pain with haematuria US NECT/IVP jaundice US Focal hepatic lesion No biliary duct dilatation Biliary dilatation Triphasic CT/MRI Pre/hepatic haundice ERCP/MRCP
Plain abdominal films Stones detection. Calcifications. Air under diaphragm.
Bony lesions :Lytic lesion in upperlumbar vertebra .
Abdominal trauma On evaluation, urgent life-threatening injuries, such as a large hemoperitoneum, a large or tension pneumothorax, or active arterial extravasation, should be sought out first. This should be followed by a thorough interrogation for injury of the abdomen and pelvis: liver and right paracolic gutter; spleen and left paracolic gutter; upper abdominal organs, arterial tree; retroperitoneum; small bowel, colon, and mesentery.
liver trauma 4-cm-thick subcapsular hematoma associated with parenchymal hematoma
Renal injury Subcapsular and perinephric haematoma.
Splenic trauma Splenic lacerations with perisplenic haematoma
Clinical evaluation of the patient is the first step in the diagnosis. Choose the appropriate imaging modality.
