Abstract
According to one embodiment, a medical image diagnostic apparatus includes an imaging unit, an image generation unit, and a display unit. The imaging unit images a subject injected with blood vessel contrast enhancement particles and diseased tissue contrast enhancement particles. The blood vessel contrast enhancement particles have the first particle size larger than the gap of vascular endothelial cells under the EPR effect. The diseased tissue contrast enhancement particles have the second particle size smaller than the gap. The image generation unit generates a medical image associated with an imaging region of the subject based on output data from the imaging unit. The display unit displays the medical image.
Claims28
A medical image diagnostic apparatus comprising:
- a medical imager configured to image a subject who has been injected with blood vessel contrast enhancement particles for contrast enhancing a blood vessel and diseased tissue contrast enhancement particles for contrast enhancing a diseased tissue and generate output data, the blood vessel contrast enhancement particle having a first particle size larger than a gap of vascular endothelial cells under an enhanced permeability and retention (EPR) effect, and the diseased tissue contrast enhancement particle having a second particle size smaller than the gap;
- processing circuitry configured to
- generate, using the output data, a medical image representing an imaging region of the subject, and
- distinguish pixel values of the medical image corresponding to the blood vessel contrast enhancement particles from pixel values corresponding to the diseased tissue contrast enhancement particles to generate data associated with a blood vessel contrast-enhanced by the blood vessel contrast enhancement particles and data associated with the diseased tissue contrast-enhanced by the diseased tissue contrast enhancement particles;
- and
- a display configured to display the medical image, wherein the displayed medical image includes the data associated with a blood vessel contrast-enhanced by the blood vessel contrast enhancement particles and the data associated with the diseased tissue contrast-enhanced by the diseased tissue contrast enhancement particles.
