Three-dimensional spiral CT cholangiography in patients with suspected obstructive biliary disease: comparison with endoscopic retrograde cholangiography.

Abstract

Spiral CT cholangiography allows accurate assessment of the biliary system in patients with suspected obstructive biliary disease.

Diagnostic Accuracy of MRCP as Compared to Ultrasound/CT in Patients with Obstructive Jaundice

“…US has been always considered the first choice technique in the study of biliary obstructive disease, due to its accessibility, speed, ease of performance and low cost [4]. Traditional Computed Tomography (CT) scan is usually considered more accurate than US for helping determine the specific cause and level of obstruction [5]. Both ultrasound and CT scan are regarded as safe and non-invasive procedures in evaluating the status of the biliary tract.…”

CT biliary cystoscopy of gallbladder polyps

“…CTVEGB can clearly show the size, configuration, location, surface and base of gallbladder polyps in accordance with color ultrasound, [1][2][3][4][5][6][7] , is capable of detecting biliary calculus, tumor, anomaly and dilatation of the biliary tract and protruding lesions with a bigger size. However, limited by the concentration of contrast medium, small polypous lesions are easily obscured and thus escaping detection by OCCT.…”

“…Axial CT data could be reconstructed into two-dimensional multi-planar or three-dimensional (3D) volume-rendered images using workstations and imagerendering software [1] . This CT technology combined with the administration of IV cholangiographic contrast agents could produce diagnostic images of the biliary tract [2][3][4][5][6][7]9,10,14] , and has been used for diagnosis of obstructive biliary disease, choledochocele, choledocholithiasis and aberrance bile ducts. The main limitation of this technique is that the rate of allergic reactions and renal or hepatic toxicity (or both) are relatively high due to by these contrast agents.…”

“…Since Klein et al [1] in 1993 reported the computed tomographic cholangiography using spiral scanning and 3D image processing, many lesions of the biliary tract have been studied [2][3][4][5][6][7][8][9][10][11][12][13][14] . In 1994 CT virtual endoscopy (CTVE) was introduced, its application in obtaining organ images has been described extensively [15][16][17][18][19][20][21][22][23][24][25][26][27][28] .…”

Expectations from imaging for pre-transplant evaluation of living donor liver transplantation

“…Yeh et al [46] also found eMRCP inferior to CTCh in visualization of second order bile ducts. Some studies have shown complete agreement between CTCh and endoscopic retrograde cholangiopancreatography [47,48] . MR imaging of the biliary ducts in general is better suited in the evaluation of pathological states wherein biliary ductal dilatation occurs secondary to obstructing calculi or masses [49] while normal caliber bile ducts of potential donors are better demonstrated with CTCh.…”
