Purpose
Manifestations of cystic fibrosis in the pancreas are gaining in clinical importance as patients live longer. Conventional ultrasonography and point shear wave elastography (pSWE) imaging are non-invasive and readily available diagnostic methods that are easy to perform. The aim of this study was to perform conventional ultrasonography and obtain pSWE values in the pancreases of patients with cystic fibrosis and to compare the findings with those of healthy controls.
Methods
27 patients with cystic fibrosis (13 women/14 men; mean age 27.7 ± 13.7 years; range 9–58 years) and 60 healthy control subjects (30 women/30 men; mean age 30.3 ± 10.0 years; range 22–55 years) underwent examinations of the pancreas with conventional ultrasound and pSWE imaging.
Results
Patients with cystic fibrosis have an echogenic pancreatic parenchyma. We found cystic lesions of the pancreas in six patients. pSWE imaging of the pancreatic parenchyma gave significantly lower shear wave velocities in patients with cystic fibrosis than in the control group (1.01 m/s vs 1.30 m/s; p < 0.001).
Conclusions
Using pSWE imaging in vivo, we have shown that the pancreas is considerably softer in patients with cystic fibrosis than in a healthy control population.
