Objective: To discuss the value of second harmonic imaging in diagnosing pancreatic masses.
Methods: Forty-seven cases with pancreatic masses and thirty controls were examined with conventional ultrasonography and second harmonic imaging. Characteristics of gray scale ultrasonography, colour Dopper flow imaging and second harmonic imaging were compared.
Results: On second harmonic imaging, different pancreatic masses presented clearer than those on conventional ultrasonography, and color flow signals in and around the pancreatic masses were shown more than those on conventional ultrasonography.
Conclusion: It is of clinical value for second harmonic imaging in detecting and diagnosing deeply-located pancreatic masses which is interfered easily bygastric gases.
