“…MR CHOLANGIOPANCREATOGRAPHY (MRCP) is accepted as an effective imaging modality for the evaluation of biliary and pancreatic disorders (1,2). The spatial and contrast resolutions of MRCP imaging are important for detecting small pathologies, such as small stones and mural nodules in pancreatic cystic lesions, and evaluating anatomy, such as the biliary tree in a normal liver donor population.…”

Purpose:To evaluate the impact of magnetic resonance cholangiopancreatography (MRCP) imaging at 1.5T and 3.0T on image quality. Materials and Methods:Fourteen volunteers were examined at both 1.5T and 3.0T using MRCP imaging performed with a breath-held two-dimensional (2D) half-Fourier acquired single-shot turbo spin-echo (HASTE) thick-slab sequence, a free-breathing navigator-triggered three-dimensional (3D) turbo spin-echo (TSE) sequence with prospective acquisition correction, and a heavily T2-weighted (T2W) sequence with breath-held multislice HASTE. All images were scored for visualization of the biliary and pancreatic ducts, severity of artifacts, image noise, and overall image quality.Results: MRCP imaging at 3.0T yielded a significant improvement in overall image quality compared to 1.5T. We found a trend for superior visualization of the biliary and pancreatic ducts at 3.0T. Heavily T2W imaging with thin sections (1.4 mm) at 3.0T provided diagnostic images and better visualization of the biliary and pancreatic ducts than heavily T2W imaging with standard sections (2.8 mm) at 3.0T. Conclusion:Our experience suggests that MRCP imaging at 3.0T has the potential to provide excellent images. Highresolution heavily T2W imaging with a small voxel size (1.3 ϫ 1.3 ϫ 1.4 mm) at 3.0T can provide diagnostic images and allow evaluation of small pathologies of the bile and pancreatic ducts, which 1.5T MRI cannot sufficiently visualize.

“…The data collected in the metaanalysis do not allow us to determine if the sensitivity and specificity of endo-ultrasonography depends on the size of the stones. However, according to another two authors [10], the sensitivity and specificity of endo-ultrasonography does not depend on the size of stones, in contrast to MRCP and ERCP, the sensitivity and specificity of which decrease non-linearly with the dimensions of the stones in the ducts.…”

The role of endoscopic ultrasonography (EUS) in contemporary diagnosis of gastrointestinal diseases

Day by day endoscopic ultrasonography (EUS) is becoming an essential diagnostic method for the assessment of solid lesions of the pancreas, cysts, pseudocysts and cystic tumours of the pancreas, enlarged mediastinal lymph nodes, staging of gastric cancer and rectal cancer, as well as lung or subepithelial tumours in the gastrointestinal tract. The ability to use this diagnostic method presents many challenges for performing specialists, from the organisation of the EUS surgery to maintaining its activity in a proper technical aspect, as well as the continuous improvement of staff qualifications. Endoscopic ultrasonography has revolutionised the practical aspects of gastroenterological practice and oncology. Particularly, EUS-guided fine-needle aspiration biopsy (EUS-FNA) of various pathologies in the gastrointestinal tract has provided invaluable effects and opportunities. This technique is becoming more and more available in Poland, creating a unique challenge to its practice. StreszczenieUltrasonografia endoskopowa (EUS) staje się z dnia na dzień kluczową metodą diagnostyczną zmian litych w trzustce, torbieli, pseudotorbieli i guzów torbielowatych trzustki, powiększonych węzłów chłonnych śródpiersia, zaawansowania raka żołądka, odbytnicy, jak również nowotworów płuc i zmian podnabłonkowych w przewodzie pokarmowym. Technika ta stawia przed wykonującymi badanie wiele wyzwań -zorganizowanie pracowni EUS, utrzymanie jej działania na należytym poziomie technicznym czy stałe podnoszenie kwalifikacji personelu. Ultrasonografia endoskopowa zrewolucjonizowała praktyczne aspekty diagnostyki gastroenterologicznej i onkologicznej, zwłaszcza biopsja cienkoigłowa kontrolowana ultrasonografią endoskopową (EUS-FNA) różnego rodzaju zmian w obrębie przewodu pokarmowego daje nieocenione efekty i możliwości. Metoda ta jest coraz bardziej dostępna w Polsce, zwiększają się również możliwości jej praktycznego doskonalenia.

“…Furthermore, its dependency on the examiner is low, and exposure to ionized radiation can be avoided [7]. Despite these advantages, the inadequate spatial resolution needed to detect small lesions is one of its shortcomings [8]. On the other hand, the following advantages have been realized with the recent development of single shot fast spin echo and other fast pulse systems: images can be obtained by short breaths, the influence of artifacts generated by movement can be reduced, and the spatial resolution capacity and signal to noise ratio are increased [9].…”

3-dimensional magnetic resonance cholangiopancreatography (MRCP) images reconstructed using the maximum intensity projection technique were analyzed qualitatively in patients diagnosed with pancreatobiliary diseases to determine their diagnostic utility. Single shot fast spin echo (SSFSE), fast spin echo (FSE) and 3-dimensional reconstructive images were acquired from 20 patients diagnosed histologically with pancreatobiliary diseases using a 3.0T MR scanner. According to qualitative analysis, the fast spin echo images and 3-dimensional reconstructed images of the hepatic duct, gall bladder and common bile duct had a higher signal to noise ratio (SNR) than the single shot fast spin echo images. Fast spin echo images and 3-dimensional reconstructed images did not show any differences. The contrast to noise ratio of the hepatic duct, gallbladder and common bile duct on the fast spin echo images and 3-dimensional reconstructed images was higher than that of the single shot fast spin echo images. The fast spin echo images and 3-dimensional reconstructed images showed similar quality.

MR Cholangiopancreatography Versus Endoscopic Sonography in Suspected Common Bile Duct Lithiasis: A Prospective, Comparative Study

Abstract: In cases of mild to moderate suspicion of choledocholithiasis, the accuracies of endoscopic sonography and MR cholangiopancreatography are similar. Because MR cholangiopancreatography is noninvasive, it may be preferred for this indication.
