“…Not all arteries are visualised due to their anatomic position, including CA, SMA and IMA [25,59]. Computerised topographic angiography and magnetic resonance angiography are precise, objective and repeatable [66,99] but method they apply (3-dimensional reconstruction of vessels filled with contrast material) is probably superior for lumen rather than diameter estimation. Also they are usually performed at diseased populations, are relative expensive and not widely available.…”

“…Our results are also similar to those of Kopka et al (19), who correlated MRA with digital subtraction angiography in 60 patients and found that small accessory arteries were missed at MRA in 3/60 patients. Small-caliber aberrant hepatic arteries are generally ligated at transplantation surgery, and their presence usually does not impact the preoperative planning for arterial anastomosis performed at transplant surgery (4).…”

Purpose:To determine the feasibility of using a multiphasic magnetic resonance (MR) examination to evaluate the hepatic arterial anatomy and parenchyma in patients awaiting orthotopic liver transplantation (OLT). Materials and Methods:Twenty consecutive patients awaiting OLT underwent multiphasic MR (using a T1-weighted 3D gadolinium-enhanced gradient-echo (GRE) sequence and two separate injections of contrast material) and computed tomography (CT) imaging; both imaging studies were performed within a 1-week period for each patient. Quantitative and qualitative assessment of the hepatic arterial system on MR data was performed. Two independent observers classified the hepatic arterial anatomy and evaluated the hepatic parenchyma from the MR data. The prospective CT interpretation was used as the gold standard.Results: Overall qualitative rating of hepatic arterial system-to-background contrast on MR data was good to excellent (average pooled score of 2.00 Ϯ 0.27), with no significant difference between the two observers after the first or second injections of contrast material. Classification of hepatic arterial anatomy by MR angiography (MRA) and CT angiography (CTA) was concordant in 85% (17/20) of patients and discordant in 15% (3/20) of patients. Focal parenchymal lesions were detected in 25% (5/20) of patients by MR and CT; however, two lesions in one patient with multiple lesions were detected only with MR. Conclusion:Multiphasic T1-weighted 3D gadolinium-enhanced MR examination can provide comprehensive evaluation of the hepatic arterial anatomy and parenchyma in patients awaiting OLT. MR may offer an advantage over CT in the detection of focal parenchymal lesions.

Purpose: With the advances in the new image techniques and 3D modeling, angiography computed tomography (A-CT) has become a very useful image to study vessels. Prevalence of Celiac Trunk (CeT) variations is common, and have a clinical relevance in preoperative planning. Our objective was to describe prevalence of CeT variations in a study population in Cali, Colombia. Methods:A retrospective study with a database was made from a selection of A-CT 3D images from January 1, 2012 to September 30, 2014, from which the CeT could be visualized. Patients under 18 were excluded, also with no 3D A-CT, or not Colombian. Frequencies, percentages were calculated using Excel and STATA software.Results: A total of 252 patients were selected, from which 10 were excluded. The most common causes of performing the A-CT were pathologies of the Aorta, followed by studies for transplantation of the kidney or liver. Variations were found in 71 (30%) patients. The most common variation was the origin of the inferior phrenic artery from the CeT in 43 (60%) patients, followed by accessories arteries to the liver in 11 (15%) patients, and the presence of a hepato-splenic trunk in 8 (11%) patients. Conclusion:Prevalence of CeT variations in our study population was higher than that reported in other studies. The use of image techniques, such as 3D A-CT, could help the surgeon or the interventional radiologist identify these variations, preventing catastrophic complications, and making safer surgeries for our patients.
