A method for obtaining an index for non-invasively identifying NASH is provided. A NASH determination method comprising a method for acquiring free radical consumption speed information by non-invasively detecting a redox reaction in a liver of a test animal in real time, comprises a step (1) of obtaining free radical concentration data by applying a magnetic resonance method to the liver as a measurement target after administering a probe into a body; a step (2) of obtaining imaging information by processing the obtained free radical concentration data; and a step (3) of obtaining a free radical consumption speed by kinetically measuring the imaging information over time, and comprises a step of determining whether or not the test animal has NASH, based on the free radical consumption speed information obtained through application to the test animal.

Free radical consumption speed information acquisition method and NASH determination method

A puncture assistance system provides information on a collapse state of a blood vessel to be punctured, caused by pressing action of an ultrasonic probe, when ultrasonic images of the blood vessel are acquired. A puncture assistance systemincludes: vascular diameter detecting meansfor detecting a vascular diameter during acquisition of the ultrasonic images from an ultrasonic diagnostic device; puncture assistance information generating meansfor generating puncture assistance information for determination of whether or not puncture is allowed to be performed based on a collapse state of a blood vessel B caused by pressing action of an ultrasonic probeagainst skin S by comparing a current vascular diameter detected by the vascular diameter detecting meanswith a standard vascular diameter stored in advance; and a monitorthat presents the puncture assistance information.
