Which biomedical technique is commonly used in detection of breast tumour ?

Options

A. MRI
B. CT-scan
C. U.S.G.
D. X–ray imaging

Answer

**Step-by-Step Solution:**

1. **Understanding Breast Tumors**: Breast tumors are abnormal growths in the breast tissue and can be benign (non-cancerous) or malignant (cancerous). Breast cancer is the most common cancer among women globally.

2. **Identifying Biomedical Techniques**: The question asks for the biomedical technique used to detect breast tumors. The options provided are MRI, CT scan, USG, and X-ray imaging.

3. **Evaluating the Techniques**:
- **MRI (Magnetic Resonance Imaging)**: This technique uses magnetic fields and radio waves to create detailed images of organs and tissues. While it can be used for breast imaging, it is not the first-line technique for breast tumor detection.
- **CT Scan (Computed Tomography)**: This imaging technique combines X-ray images taken from different angles and uses computer processing to create cross-sectional images. It is not typically used for breast tumor detection.
- **USG (Ultrasonography)**: Also known as sonomammography, this technique uses sound waves to produce images of the inside of the breast. It is commonly used to evaluate palpable masses and as a follow-up for abnormal mammogram results.
- **X-ray Imaging**: While mammography is a specific type of X-ray used for breast imaging, it is not referred to simply as X-ray imaging.

4. **Conclusion**: Among the options provided, the most commonly used biomedical technique for the detection of breast tumors is **USG (Ultrasonography)**.

**Final Answer**: USG (Ultrasonography)
