Abstract
PURPOSE
To correlate Magnetic resonance angiography (MRA) with computed tomography for the diagnosis of splanchnic artery aneurysms.
MATERIALS-METHODS
We retrospectively reviewed the MRA findings of splanchnic arteries performed in 16 patients with known splanchnic aneurysms. Sixteen patients underwent computed tomography (CT), and MRA. Conventional angiogram was performed to confirm the diagnosis in six cases. This study was conducted on a 1.5T MR Symphony system (Siemens, Erlangen, Germany). CE-MRA was performed by using a 3D RF-spoiled FLASH sequence. Acquisition of source images was performed in the coronal plane and reconstructed by means of maximum-intensity projection (MIP) post-processing.
RESULTS
Patient population included 7 men and 9 women aged from 31 to 85 years old (mean age 59.5 years old). Splanchnic aneurysms were located as follows: splenic (n=5), hepatic (n=6), celiac trunk (n=4) and gastroduodenal (n=1). In 9 cases, MRA provided results similar to CT. In 3 cases, MRA provided more accurate information on the location of the aneurysm or detected additional aneurysms. In 4 patients, a diagnosis of aneurysm was made first or only made on MRA.
CONCLUSION
This small series showed a good correlation between CT and MRA for detection and characterization of splanchnic aneurysms.
