Application of 3D Power Doppler Ultrasonography in Soft Tissue Neoplasms

Soft-tissue tumor differentiation using 3D power Doppler ultrasonography with echo-contrast medium injection.

BACKGROUND We aimed to evaluate the ability of 3-dimensional power Doppler ultrasonography to differentiate soft-tissue masses from blood flow and vascularization with contrast medium. METHODS Twenty-five patients (mean age, 44.1 years; range, 12-77 years) with a palpable mass were enrolled in this study. Volume data were acquired using linear and convex 3-dimensional probes and contrast medi...

Application of immunohistochemistry to soft tissue neoplasms.

CONTEXT Soft tissue tumors are composed of numerous and complex diagnostic entities. Because of this complexity and the recognition of an intermediate malignancy category including some tumors with a deceptively bland histologic appearance, soft tissue tumors may represent a major diagnostic challenge to the general practicing pathologist. OBJECTIVE To correctly diagnose soft tissue tumors wi...

Application of 3D Ultrasonography in Detection of Uterine Abnormalities

Differentiation of benign and malignant superficial soft-tissue masses using grayscale and color doppler ultrasonography.

BACKGROUND This study was performed to evaluate the usefulness of high-resolution grayscale and color Doppler ultrasound to distinguish benign from malignant soft-tissue masses on the basis of ultrasonographic patterns. METHODS We enrolled 398 female and 420 male patients aged 1-104 years (mean, 49.8 years). All presented with a palpable nodule or mass located superficially in the body. Each ...
