Which one of the techniques is used for the detection of cancers?

Options

A. Magnetic Resonance imaging (MRI)
B. Radiography (X-rays)
C. Computed Tomography (CT)
D. All of these

Answer

To determine which techniques are used for the detection of cancers, we can analyze the options provided:

### Step-by-Step Solution:

1. **Understanding MRI (Magnetic Resonance Imaging)**:
- MRI is a non-invasive imaging technology that produces detailed 3D images of internal body structures.
- It is particularly useful for detecting brain tumors and assessing brain injuries.
- **Conclusion**: MRI is a technique used for cancer detection.

2. **Analyzing Radiography (X-rays)**:
- Radiography involves the use of X-rays, which are a form of ionizing radiation.
- This technique creates images of internal body structures, allowing for the identification of tumors or cancerous growths.
- **Conclusion**: Radiography (X-rays) is also a technique used for cancer detection.

3. **Exploring Computed Tomography (CT)**:
- CT scans are diagnostic imaging tests that create detailed images of internal organs.
- This technique is effective in identifying tumor formations or cancer in various parts of the body.
- **Conclusion**: CT scans are another technique used for cancer detection.

4. **Final Evaluation**:
- All three techniques—MRI, radiography (X-rays), and CT scans—are valid methods for detecting cancers.
- Therefore, the correct answer to the question is that all of these techniques are used for cancer detection.

### Final Answer:
All of the options provided (MRI, radiography, and CT) are techniques used for the detection of cancers.
