Table 2.

Comparison between different diagnostic modalities.

Accuracy Specificity Sensitivity Indication Limitation
MDCT 40–50% 60–90% 50–90% Basic staging study Lacks accuracy in neo- adjuvant and follow – up setting
MRI 70–80% 70–90% 55–75% Similar benefits to MDCTNewer modalities (DWI sequence, newer contrast agents) have the potential to increase accuracy Not widely availableSome of its characteristics are still under investigationExpensive
EUS 50–80% 80–90% 70–80% Accurate for regional lymph nodesAddition of FNA offers tissue confirmation Inadequate for distal metastasesOperator – dependentInherent limitations in certain anatomic areas
PET 30–40% 40–50% >90% High sensitivityDetects distant metastases with higher sensitivity than other modalities Inadequate for loco – regional diseaseHigh rate of false positive resultsExpensiveNot widely available
