The oldest form of imaging. They are excellent for looking at dense structures like bones or finding foreign objects [17, 31].

Uses powerful magnets and radio waves—no radiation involved! It is the gold standard for looking at soft tissues like the brain, muscles, and ligaments [17, 19].

Using imaging (like live X-rays or ultrasound) to guide minimally invasive procedures, such as placing stents or treating tumors [26, 36].

Using high-energy radiation to treat diseases like cancer [36]. 🛠️ The Common Imaging Modalities

The most important part. This is the radiologist's professional conclusion and diagnosis based on the findings [7, 10]. 💡 Quick Tip for Students

Different "tools" are used depending on what the doctor needs to see. Here are the four most common types of scans:
