**Core Concept**
The best investigation to detect rupture of silicon breast implants involves imaging techniques that can accurately visualize the implant and surrounding tissue. **Magnetic Resonance Imaging (MRI)** is highly sensitive for detecting implant ruptures.
**Why the Correct Answer is Right**
MRI is the most accurate method for detecting silicone breast implant ruptures, especially intracapsular ruptures, where the silicone gel leaks out of the implant but is still contained within the fibrous capsule. This is because MRI can distinguish between the silicone gel and the surrounding tissue, allowing for clear visualization of any leakage.
**Why Each Wrong Option is Incorrect**
**Option A:** Ultrasound is less sensitive than MRI for detecting implant ruptures, especially for intracapsular ruptures.
**Option B:** Mammography is not the best modality for detecting silicone implant ruptures as it is primarily used for breast tissue evaluation.
**Option D:** CT scans are also less sensitive than MRI for this specific purpose.
**Clinical Pearl / High-Yield Fact**
Remember, MRI is the gold standard for evaluating silicone breast implant integrity, particularly for detecting ruptures that may not be clinically apparent.
**Correct Answer:** D. MRI. Magnetic Resonance Imaging
