Here are some common types of scans:

Imaging Scans
1. CT (Computed Tomography) Scan: Uses X-rays and computer technology to produce cross-sectional images.
2. MRI (Magnetic Resonance Imaging) Scan: Uses magnetic fields and radio waves to produce detailed images.
3. Ultrasound Scan: Uses high-frequency sound waves to produce images.
4. PET (Positron Emission Tomography) Scan: Uses small amounts of radioactive material to produce images of internal structures.
5. Mammography: A type of X-ray imaging used to produce detailed images of the breast tissue.

Diagnostic Scans
1. Bone Density Scan (DXA): Measures bone mineral density to diagnose osteoporosis.
2. Thyroid Scan: Uses radioactive iodine to evaluate thyroid function.
3. Gallbladder Scan: Uses radioactive material to evaluate gallbladder function.
4. Renal Scan: Uses radioactive material to evaluate kidney function.

Specialized Scans
1. Angiogram: Uses X-rays and contrast material to visualize blood vessels.
2. Echocardiogram: Uses ultrasound waves to produce images of the heart.
3. Colonoscopy: Uses a flexible tube with a camera to visualize the colon.
4. Endoscopy: Uses a flexible tube with a camera to visualize internal organs.

These scans help healthcare professionals diagnose and treat various medical conditions.
