Traditionally these cavities are divided into four quadrants: right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ). Diagnostic imaging of these is challenging, related to the highly consistent tissue densities, which then require contrast medium use to enable differentiation/assessment.
