ABSTRACT
Background:
Pancreatic cancer is a
fatal disease with high mortality rate. Imaging
has a significant and decisive interplay in the diagnosis process and in
staging of the patients with carcinoma. Thus MRI detection of linear
metastasis in patients with pancreatic carcinoma is of great importance.
Objective:
The purpose of the study
was to find out the diagnostic accuracy
of MRI in the detection of linear metastasis in patients with pancreatic
carcinoma
Methodology:
Systematic literature
search was conducted by the help of following search engines: Google scholar,
PubMed, NCBI, Medline and Medscape databases from 1999 up to 2020 for names or
pancreatic carcinoma, MRI, diagnostic accuracy of MRI in carcinoma, management
of motion artifact in MRI, RADAR sequence for motion compensation in MRI. Only
those studies were included in this review study which showed the role MRI
detection in the patients with pancreatic carcinoma. Total 33 studies were
selected and evaluated for the current study. All data extracted from them was
further analyzed through meta-analysis.
Results: According to literature MRI detection
technique is responsible in the detection of linear metastasis in pancreatic
carcinoma. The diagnostic accuracy of the test was high with four out of five
studies indicating diagnostic accuracy greater than 90%. Moreover, the sensitivity
and specificity of the technique is high i.e. above 0.80 and 0.78 respectively.
Thus MRI stands as the significant and accurate marker for the detection of
metastasis especially in the case of pancreatic adenocarcinoma.
Conclusion:
The reviewed literature indicated that MRI possesses high diagnostic
accuracy for detection of pancreatic carcinoma. The sensitivity and specificity
of MRI was also high. The results indicated that the use of MRI may help in
early detection of Pancreatic Cancer.
