EFFICACY OF NAVIGATOR-TRIGGERED PACE TECHNIQUE MRCP IN CHOLEDOCHOLITHIASIS

Abstract

Aim: The navigator-triggered Prospective Acquisition Correction Enhancement technique is a method used to eliminate respiratory motion artifacts caused in magnetic resonance cholangiopancreatography examinations. The purpose of this study was to compare the diagnostic accuracy of navigator-triggered Prospective Acquisition Correction Enhancement tecnique magnetic resonance cholangiopancreatography examination with endoscopic retrograde cholangiopancreatography as a gold standard reference in presence of choledocholithiasis. 
 Materıal and Method: The diagnostic rates of magnetic resonance cholangiopancreatography examination performed with Prospective Acquisition Correction Enhancement technique in the diagnosis of choledocholithiasis were compared according to the results of the endoscopic retrograde cholangiopancreatography examination, which was accepted as a gold standard reference. 
 Results: Among 107 patients included in the study, 40 patients with magnetic resonance cholangiopancreatography and 36 patients with endoscopic retrograde cholangiopancreatography were diagnosed with choledocholithiasis. endoscopic retrograde cholangiopancreatography showed the presence of choledocholithiasis in 36 patients among 40 patients diagnosed as choledocholithiasis with magnetic resonance cholangiopancreatography. The positive predictivity value of the magnetic resonance cholangiopancreatography examination performed with the Prospective Acquisition Correction Enhancement technique was 90%, the negative predictivity value was 98.5%, the sensitivity was 97.3%, the specificity was 94.3%, and the diagnostic accuracy was 95.3%. 
 Conclusıon: We think that navigator-triggered magnetic resonance cholangiopancreatography examination obtained with Prospective Acquisition Correction Enhancement technique is a reliable method with high accuracy in the diagnosis of choledocholithiasis.
