How to Diagnose Cholecystitis

Ultrasound is the most common and accurate method for diagnosing cholecystitis. This non-invasive imaging test allows doctors to examine the gallbladder for signs such as thickened gallbladder walls, gallbladder swelling, or the presence of gallstones—key indicators of inflammation. Compared to other diagnostic tools, ultrasound is fast, safe, and cost-effective.

In some cases, CT scans and MRI may also be used to evaluate gallbladder health, although they are generally more expensive and less accessible than ultrasound. While CT scans can provide detailed cross-sectional images, MRI offers a more detailed view without radiation exposure. However, these methods are typically reserved for more complex cases or when ultrasound results are inconclusive.

When it comes to detecting small stones or bile duct issues, MRI and MRCP are especially valuable. MRCP, or Magnetic Resonance Cholangiopancreatography, is a specialized type of MRI that provides detailed images of the bile ducts and pancreatic duct. This technique is particularly useful when symptoms strongly suggest gallstone disease but have not been detected through ultrasound.

For patients experiencing clear symptoms of gallstones, MRCP is often recommended for a definitive diagnosis. It helps doctors identify issues in both the gallbladder and bile ducts, ensuring a comprehensive evaluation and guiding appropriate treatment decisions.
