Imaging methods | Advantages | Disadvantages |
---|---|---|
MRI | Provide excellent spatial resolution and soft tissue contrast; visualize of intricate anatomical details; without ionizing radiation damage | Expensive; excluded patients with magnetic metal |
CT | Provide precise anatomical layer information; good imaging capability for hard tissues | Low soft tissue resolution; ionizing radiation damage |
Ultrasound | Provide blood flow velocity information; Good penetrative ability; high safety | Hard to image vascular structure; unable to provide functional imaging; low image contrast |
PAI | Provide functional information; High resolution and high contrast; deep-tissue optical ability | Strong dependence on tissue optical properties; safety of contrast agents |
DSA | Provide precise vascular structure and branches; assess blood flow dynamics; Evaluate interventional procedures effectiveness | Invasive; large amount of contrast agents |
