cystoscopy
cross - sectional imaging using x - rays.
magnetic imaging for detailed organ views.
basic imaging using radiation.
uses sound waves to create images of organs.

Explanation:

• Ultrasound: It is a medical imaging technique that uses high - frequency sound waves. These sound waves are emitted into the body, and when they encounter different tissues (with different acoustic properties), they are reflected back. The machine then processes these reflected waves to create an image of the internal organs. So, it matches with "Uses sound waves to create images of organs."
• CT Scan (Computed Tomography): It takes multiple X - ray images from different angles around the body. Using computer algorithms, these 2D X - ray images are combined to create cross - sectional (slice - like) images of the internal structures. Hence, it matches with "Cross - sectional imaging using X - rays."
• MRI (Magnetic Resonance Imaging): It uses a strong magnetic field and radio waves. The magnetic field aligns the hydrogen atoms in the body's tissues. When radio waves are applied, these atoms emit signals. The machine detects these signals and, through complex calculations, creates detailed images of the organs, especially useful for soft - tissue imaging. So, it matches with "Magnetic imaging for detailed organ views."
• X - ray: It is a form of electromagnetic radiation. When X - rays pass through the body, different tissues (dense tissues like bones absorb more X - rays, while less dense tissues like soft tissues allow more X - rays to pass through) create an image on the X - ray film or detector. It is a relatively basic form of imaging compared to CT and MRI in terms of the level of detail and the type of information it provides, and it matches with "Basic imaging using radiation."

Answer:

1. Ultrasound - Uses sound waves to create images of organs.
2. CT Scan - Cross - sectional imaging using X - rays.
3. MRI - Magnetic imaging for detailed organ views.
4. X - ray - Basic imaging using radiation.
