Introduction

Imagine this: you have persistent back pain or sudden abdominal discomfort. Your doctor advises a scan, but you’re left wondering — Do I need an MRI? A CT scan? Or just an ultrasound?

At Truscan Diagnostics, JP Nagar, Bengaluru, we see this confusion every single day. Most patients hear about these tests, but very few know the differences, safety, or purpose of each. Don’t worry — by the end of this article, you’ll know exactly what these scans are, when they’re used, and which one might be right for you.

The Basics: What Are These Scans?

1. Ultrasound (USG)

How it worksUses high-frequency sound waves (no radiation).

Best for:Pregnancy scans, gallstones, kidney stones, liver diseases, abdominal pain, thyroid nodules.

Advantages:Safe, painless, no side effects, affordable.

Limitations:Cannot see through bones or air-filled organs like lungs.

2. CT Scan (Computed Tomography)

How it works:Uses X-rays with computer processing to give detailed cross-sectional images.

Best for:Brain injuries, lung infections, fractures, cancers, internal bleeding, kidney problems.

Advantages:Quick (few minutes), detailed view of bones and internal organs.

Limitations:Uses radiation, so repeated scans are avoided unless necessary.

3.MRI (Magnetic Resonance Imaging)

How it works:Uses strong magnetic fields and radio waves (no radiation).

Best for:Brain, spinal cord, joints, ligaments, soft tissues, tumors.

Advantages: Extremely detailed, especially for brain, nerves, and muscles.

Limitations:Expensive, takes longer (30–60 mins), not suitable for patients with metal implants or pacemakers.

Which Test is Right for You?

Your doctor decides the test based on symptoms, medical history, and suspected condition. Here’s a simple guide:

Condition Best Test Why
Pregnancy check-up Ultrasound Safe, no radiation.
Kidney stones / gallstones Ultrasound or CT CT gives clearer stone location, USG is first step.
Head injury / stroke CT or MRI CT for emergencies, MRI for detailed brain mapping.
Joint pain / ligament tear MRI Best for muscles, ligaments, soft tissues.
Chest infection / lung cancer CT Scan Detailed view of lungs.
Tumor or cancer follow-up MRI / CT Both are used depending on location.

Frequently Asked Questions

Not always. MRI is better for soft tissues (brain, joints), while CT is better for bones, chest, and emergency cases.

For many cases like gallstones or kidney stones, yes. But if results are unclear, doctors may suggest CT

No. All three are non-invasive and painless. Only contrast scans may require an injection for better clarity.
