Abstract

Objectives: Evaluating the role of CT scanner 64 multidetector in diagnosing of pancreatic head tumor.
Subjects and methods: 57 patients were diagnosed of pancreatic head tumor on MSCT 64 multi-detector and were
operated with pathology result confirmed from January 2012 to December 2012 in Viet Duc hospital.
Results: The sensitivity, specificity, fault negative rate, accurate diagnosis and positive predictive value of MSCT 64
detectors in definite diagnosis were 96%, 100%, 3.4%, 98%, and 100% respectively. The sensitivity, specificity, fault negative rate,
accurate diagnosis and positive predictive value of MSCT 64 detectors in local invasive diagnosis were 74%, 87%, 26%, 86%,
and 94% respectively. The evaluation vascular invasion were with the Se of 75%, Sp of 95%, FNR of 25%, ACC of 85%, PPV of 88%.
The value of metastasis diagnosis were with Se of 57%, Sp of 85%, FNR of 43%, ACC of 71%, PPV of 72%. Accuracy of surgery
technique proposing was 87.7%.
Conclusion: CT scanner 64 multi-detector has high sensitivity and specificity in definitive diagnosis, evaluating the invasion and
proposing the diagnosis possibilities.
