発明の名称 (英語) ULTRASOUND DIAGNOSTIC DEVICE NEW
発明の概要(英語) An ultrasound diagnostic device 100 determines the effects of cancer treatment on a specific site of a subject on the basis of ultrasonic echo signals reflected by the subject. The ultrasound diagnostic device 100 is provided with: a first probe 11 which emits ultrasonic waves to the subject and receives an echo signal; an operation unit 8 for receiving a selection operation for the position of a specific site from a user; a second probe 12 which emits ultrasonic waves to warm the specific site; and a control unit 5 which acquires thermal property information for the specific site on the basis of an echo signal acquired before warming the specific site with the ultrasonic waves emitted from the second probe and an echo signal acquired after warming, and determines the presence or absence of a contrast agent at the specific site on the basis of the thermal property information.
従来技術、競合技術の概要(英語) BACKGROUND ART
Cancer, especially hepatocellular carcinoma (hepatoma) non-resectable as therapy, chemical therapy (transcatheter arterial chemoembolization,TACE) hepatic artery embolization has been known. TACE is, after injection of anti-cancer liver, gelatin sponge or the like is injected into the solid of the embolic material to shut off the supply of nutrients of liver cancer, liver cancer ischemic necrosis is a technique. TACE is, typically, by the catheter to inject an anti-cancer liver, a mixture of contrast agent and the anti-used (emulsion). Is an example of a contrast agent, (registered trademark) Lipiodol (iodized poppy oil fatty acid ethyl ester) is in.
