This study aimed to evaluate the diagnostic performance of different imaging techniques for preoperative detection of pelvic fistula. Imaging and classification of female genital abnormalities considerably pelvic floor fistulas are significant. We conducted a systematic review of the available literature to highlight the effectiveness of different radiological imaging techniques (X-RAY,U/S,CT,MRI) for the diagnosis of different types of pelvic fistulas to see the limitations of conventional scanning and testing over modern imaging techniques and to show the effectiveness of choosing one imaging modality over other depending upon multiple dynamics e.g., site and types of fistula. The controlled and regular research cases (n= 9) available in English from 2011 to 2020 were included in criteria of research. The evidence databases were used for assessment of certain studies analytically by way of PEDro scale and explicated under decision guidelines. In all relevant articles were identified and included in this systematic review. The radiological techniques showed improved diagnostic performance that established the effectiveness of imaging advancement for administration and treatment of pelvic fistula. Conventional methods have less sensitivity and specificity as compared to modern techniques. X-RAY fistulography and ultrasonography has less sensitivity and specifity as compared to CT scan but still found beneficial in the diagnosis of colovaginal, uterovesical fistula and considered as the most basic clue about the existence of a malignant fistula respectively.it is verified that MDCT is the safer accurate and offered more detailed defects in diagnosis of urogenital, urethrorectal, lower urogenital tract fistulas, upper and middle vaginal fistulas colovesical fistulas(along with X-RAY) and prostate symphyseal fistula(along with MRI).It has been concluded that MRI can access colovesical fistulas inherited vaginal fistulas and prostate symphyseal fistulas(along with CT) more efficiently. It has been concluded that diagnostic imaging for all pelvic fistula is useful, to help the physicians, particularly radiologists, in diagnosis of pelvic fistulas. The choice of imaging technique is dependent upon multiple factors. Advanced medical imaging techniques XRAY,MDCT MRI) are considered more recommended choices as compared to conventional imaging.
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. Key words: Pancreatic carcinoma, Linear metastasis, Magnetic Resonance Imaging
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
