  2. Percutaneous Nephrolithotomy (PCNL)

  3. Ureteroscopy

  4. Laser Lithotripsy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Extracorporeal Shock Wave Lithotripsy (ESWL) revolutionized kidney stone treatment by using high-energy shock waves to break down kidney stones non-invasively.

Multiple choice

What is the basic principle behind the operation of a magnetic resonance imaging (MRI) machine?

  1. Electromagnetic induction

  2. Nuclear magnetic resonance

  3. X-ray imaging

  4. Ultrasound imaging
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

MRI machines utilize the principle of nuclear magnetic resonance, where certain atomic nuclei, such as hydrogen, align with an external magnetic field and emit radio waves when exposed to radiofrequency pulses.
