Resumo: | Background: Abbreviated Magnetic Resonance Imaging (MRI) protocols have emerged to reduce the examination time of the long protocols eliminating unnecessary pulse sequences to answer a targeted clinical question, without compromising diagnostic information. The objective of this study was to evaluate the diagnostic accuracy of an abbreviated Magnetic Resonance cholangiopancreatography (A-MRCP) protocol in patients with suspected choledocholithiasis. Methods: This retrospective study evaluated patients (ages 10+ years) that performed consecutive MRCP examination from October 2019 to June 2020, with the clinical suspicion of choledocholithiasis. Readers first evaluated the biliary tree using a four-sequence A-MRCP protocol and later reviewed the entire conventional eleven-sequence MRCP. Presence of choledocholithiasis, stone size, common hepatic duct caliber, and additional findings were evaluated. Results: One-hundred fifty-two MRI scans for 148 patients with MRCP were included (62,8% female, mean 50.9 years). The prevalence of choledocholithiasis was 32.2%. The accuracy of the abbreviated MRCP protocol for choledocholithiasis was 98,7%. There was no difference between the performance of the abbreviated and conventional MRCP image sets for detection of choledocholithiasis (kappa=0.970), with a sensitivity of 98% and a specificity of 99%. There was excellent inter-reader agreement evaluating for choledocholithiasis on both imaging sets of MRCP protocols (kappa = 0.925). Conclusions: The abbreviated MRCP protocol demonstrated excellent accuracy in diagnosing choledocholithiasis, similar to the conventional protocol, with the potential to reduce examination time and improve patient comfort. |

O objetivo do estudo foi avaliar a acur?cia diagn?stica de um protocolo abreviado de colangiopancreatografia por resson?ncia magn?tica (colangioRM) em pacientes com suspeita de coledocolit?ase. M?todos: Estudo retrospectivo, com pacientes acima de 10 anos que realizaram exame de colangioRM, entre outubro de 2019 a junho de 2020, com suspeita cl?nica de coledocolit?ase. Os observadores, radiologistas especialistas, primeiro avaliaram a ?rvore biliar usando um protocolo abreviado de colangioRM composto por quatro sequ?ncias de pulso e, posteriormente, revisaram o protocolo convencional de colangioRM de onze sequ?ncias. A presen?a de coledocolit?ase, o tamanho do c?lculo, o calibre do ducto hep?tico comum e achados adicionais foram avaliados. Resultados: 148 pacientes foram inclu?dos, sendo 62,8% do sexo feminino, com m?dia de 50,9 anos de idade. A preval?ncia de coledocolit?ase foi de 32,2%. A acur?cia do protocolo abreviado de colangioRM para coledocolit?ase foi de 98,7%. N?o houve diferen?a entre o desempenho dos protocolos abreviado e convencional de colangioRM para a detec??o de coledocolit?ase (k = 0,970), com uma sensibilidade de 98% e uma especificidade de 99%. Al?m disso, observou-se excelente concord?ncia entre observadores na avalia??o de coledocolit?ase em ambos os protocolos de colangioRM (k = 0,925). Conclus?o: o protocolo abreviado de colangioRM apresentou excelente acur?cia para o diagn?stico de coledocolit?ase quando comparado ao protocolo convencional.Submitted by PPG Medicina e Ci?ncias da Sa?de (medicina-pg@pucrs.br) on 2021-11-26T13:13:26Z No. of bitstreams: 1 Disserta??o Angela Agostini - PDF.pdf: 2720037 bytes, checksum: 032d3c385ed78fb24b4647c32c521482 (MD5)Approved for entry into archive by Sarajane Pan (sarajane.pan@pucrs.br) on 2021-11-26T20:39:00Z (GMT) No. of bitstreams: 1 Disserta??o Angela Agostini - PDF.pdf: 2720037 bytes, checksum: 032d3c385ed78fb24b4647c32c521482 (MD5)Made available in DSpace on 2021-11-26T20:50:09Z (GMT).
