F.A.S.T. ULTRASOUND

INDICATIONS:

Medical Necessity: Evaluate for intraperitoneal or pericardial fluid
Structures studied: Hepatorenal space, splenorenal recess, pericardial space, and pelvic views.

REQUIRED IMAGES:

3 Components to a FAST Exam (include each as clinically indicated) : Abdomen, Cardiac, Thoracic

1.) Abdomen

  • RUQ - include hepatorenal space, sub-diaphragmatic space, and inferior edge of the liver

  • LUQ -  include splenorenal space, sub-diaphragmatic space, left paracolic gutter

  • Pelvis - transverse and sagittal views

2.) Cardiac

  • Obtain any one of the Parasternal Long Axis, Apical 4 Chamber, or Subxiphoid Views

 

3.) Thoracic

  • Anterior Chest - Right and Left

  • Lateral Inferior Chest, Coronal View - Right and Left

    • Visualize Diaphragm and Spine.  These can be obtained concurrent with abdominal RUQ and LUQ views

 

HOW TO SCAN - FAST

1.) Video in the longitudinal plane, fanning through Morrison’s pouch (hepatorenal space) to include the inferior tip of the liver/inferior pole of right kidney.

2.) Video clip fanning through the bladder in both the longitudinal and transverse planes. 

3.) Video clip in the longitudinal plane scanning through the spleen and kidney. Must include diaghram, spleno-renal space, and inferior tip of the spleen/lower pole of left kidney.

4.) Video clip of the subxiphoid cardiac view in the transverse plane.

5.) If subxiphoid view is techniquely inadequate, a video clip of the parasternal long axis will suffice. 

6.) Obtain one static representative image.
