Contrast-enhanced sonography with Sonazoid as a new diagnostic tool for splenic hamartoma: a single case report
We report a case of non-symptomatic splenic hamartoma in a 40-year-old woman detected as an abdominal tumor by screening ultrasonography. The tumor was 4 cm in diameter, round, slightly hypoechoic, and associated with a cystic lesion. The tumor region was stained on enhanced computed tomography with prolonged enhancement, while the cystic lesion was not. The mass appeared as mainly isointense with partial hyperintensity on T1-weighted and as a mixed hypo- and hyperintense region on T2-weighted magnetic resonance images. 99mTc-labeled colloid scintigraphy demonstrated uptake in only the tumor region. CEUS with Sonazoid...

Splenic cystic lymphangioma with atypical ultrasound findings
We describe the case of an isolated splenic cystic lymphangioma affecting an elderly female patient. The patient was asymptomatic and the blood tests were normal. The tumor appeared on gray-scale ultrasound as an inhomogeneous, mostly hyperechoic septated mass, which is atypical for a cystic lymphangioma. Contrast-enhanced ultrasound and contrast-enhanced computed tomography suggested the benign nature of the tumor and narrowed the diagnosis. The tumor received histopathological confirmation after splenectomy. Various CT and MRI findings in splenic lymphangiomas have been described, but very few reports regarding CEUS exis...

Weighted Capon beamformer combined with coded excitation in ultrasound imaging
Abstract Background Capon-based beamformers are well-known methods to improve the SNR and quality of medical ultrasound images. Furthermore, they can improve the resolution of the images unexpectedly more than conventional DAS beamformers. Another method used in radar, sonar, and ultrasound imaging to increase the SNR is coded excitation with linear frequency-modulated signal (chirp). Method In this paper, we illustrate that the combination of coded excitation with a Capon beamformer provides better resolution and higher SNR. However, this combination su...

Prenatal diagnosis and postnatal outcome of persistent right ductus arteriosus: a report of three cases
Abstract The ductus arteriosus is a fetal vascular connection between the main pulmonary artery and aorta that diverts blood away from the pulmonary bed. Left and right ductus arteriosi emerge from embryological aortic arches. In normal embryologic cardiac development, both right aortic and ductal arches regress and the left ones persist. Persistent right ductus arteriosus (rDA) is one of the congenital anomalies of the ductal arch. In this paper, we report three cases of persistent right ductus arteriosus with right aortic arch.

The lobar approach to breast ultrasound imaging and surgery
Abstract Breast cancer is a lobar disease in the sense that, at the earliest stages, the cancer is structurally confined to a single sick lobe. The subgross morphology of breast carcinoma is often complex, as multiple invasive foci are frequently present and the ductal system often contains an extensive in situ component. Adequate preoperative visualization of all of the malignant structures within the affected breast and preoperative mapping of the lesions in relation to the surrounding normal structures are essential for successful image-guided breast surgery and therefore are key factors in assuring adequate lo...
