Ultrasound is not only used for diagnostic purposes but it also can be applied therapeutically so far that?nowadays high-intensity focused ultrasound (HIFU) even represents a novel non-invasive treatment modality for various solid tumors. HIFU works by causing selectively deep tissue destruction of target lesions within the body without harming adjacent and overlying structures. In this article, we present an overview on both the mode of action and requirements for a HIFU treatment as?well as on the safety and the current status of indications and possible applications with regard to benign and malignant gynecological diseases. Based on numerous studies and original articles, HIFU proved to be an effective and low-risk treatment option particularly for uterine fibroids and adenomyosis, but it also seems to be effective for breast fibroadenomas or even for breast cancer in special cases and other rare entities.
The purpose of this report is to describe the ultrasonographic features of hepatic inflammatory myofibroblastic tumour (IMT). This tumour presented as an area of periportal soft-tissue infiltration. Because periportal infiltration is a common feature in both IMT and other malignant tumours of the hepatic portal, histological examination should be considered before final diagnosis and treatment.
Intratumoural flow signals favour a malignant tumour. The absence of flow signals is a frequent finding in benign lesions but does not rule out malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
