To assess

Measure the dimensions of the spleen and evaluate for focal abnormalities like masses or infarctions.

 

Limitations

None

 

Patient preparation

None

 

Equipment setup

Depending on the patient's body type, a transducer with a curvilinear array and a frequency range of approximately 2 to 9 MHz enables appropriate penetration and resolution.

 

Common pathology

Left upper quadrant mass or tenderness

• Palpable spleen

• Thrombocytopenia or other conditions associated with splenomegaly (portal hypertension, lymphoproliferative disorders, infiltrative disorders, infections, etc.)

• Follow up on known splenomegaly

 

Scanning Technique

A complete examination includes an evaluation of the spleen, including the left hemidiaphragm and adjacent pleural space if possible

• Deep inspiration facilitates splenic imaging.

• Extensive use of cine scans enables a more accurate assessment of focal or indeterminate findings.

• Spleen longitudinal measurement: taken from the most inferior apex to the highest point along the diaphragm, crossing the splenic hilum.

• Transverse measurements: oriented 90 degrees relative to longitudinal measurements, with callipers situated at the same level for the greatest thickness and width.

• Focal abnormalities must be documented using size measurements and colour Doppler imaging.

• Evaluate for splenic vein thrombosis and perisplenic varices using colour Doppler at the hilum and, if abnormal, spectral Doppler.
