This guide explains common imaging terms, patterns, and follow-up questions so you can better understand your radiology report. Always confirm important findings with your radiologist or treating clinician.

Introduction

The meniscus is a C-shaped cartilage pad in the knee joint. Meniscus tears are common orthopedic injuries diagnosed with T2 or PD weighted MRI sequences.

MRI Visual Clues for Meniscus Tears

  • Abnormal High Signal Touching the Joint Surface: The golden standard for a tear on MRI is a white line inside the black meniscus triangle that extends to the upper or lower boundary.
  • Morphological Distortion: The meniscus appears frayed, displaced, or significantly smaller than expected.
