Free-breathing radial volumetric interpolated breath-hold examination vs breath-hold cartesian volumetric interpolated breath-hold examination magnetic resonance imaging of the liver at 1.5T

Figure 1 Bar plot showing the estimated mean score and 95%CI of each image quality parameter for radial volumetric interpolated breath-hold examination and cartesian volumetric interpolated breath-hold examination. VIBE: Volumetric interpolated breath-hold examination; rVIBE: Radial VIBE; cVIBE: Cartesian VIBE.

Figure 2 Magnetic resonance imaging of the abdomen in a 68-year-old male performed to follow-up a microcystic serous cystadenoma of the pancreas. The patient had an atrial septal defect closure device in place. Axial pre-contrast rVIBE (A), pre-contrast cVIBE (B), post-contrast rVIBE (C), and post-contrast cVIBE (D) show a hemangioma in the right liver (white arrows) with better margin delineation on pre- and post-contrast cVIBE than on pre- and post-contrast rVIBE. A radiating streak artifact in the central liver (black arrows) was seen only on pre- and post-contrast rVIBE images. VIBE: Volumetric interpolated breath-hold examination; rVIBE: Radial VIBE; cVIBE: Cartesian VIBE.

Figure 3 Magnetic resonance imaging of the abdomen in a 40-year-old male performed to follow-up after resection of an adrenocortical carcinoma. Axial pre-contrast rVIBE (A), pre-contrast cVIBE (B), post-contrast rVIBE (C), and post-contrast cVIBE (D) show improved hepatic vessel delineation on pre- and post-contrast cVIBE compared to pre- and post-contrast rVIBE images. VIBE: Volumetric interpolated breath-hold examination; rVIBE: Radial VIBE; cVIBE: Cartesian VIBE.

Figure 4 Magnetic resonance imaging of the abdomen in a 53-year-old female with breast cancer performed to follow-up of a pancreatic cyst. Axial pre-contrast rVIBE (A), pre-contrast cVIBE (B), post-contrast rVIBE (C), and post-contrast cVIBE (D) show superior lesion conspicuity of a tiny hepatic cyst in segment 7 of the liver (white arrows) on pre- and post-contrast cVIBE compared with post-contrast rVIBE images. The lesion was not identified on the pre-contrast rVIBE image. The pre- and post-contrast rVIBE images also illustrate a smooth radiating artifact (black arrow) in the left liver. VIBE: Volumetric interpolated breath-hold examination; rVIBE: Radial VIBE; cVIBE: Cartesian VIBE.

Figure 5 Magnetic resonance imaging of the abdomen in a 61-year-old female with breast cancer performed to further characterize an incidentally-detected left adrenal nodule. Axial pre-contrast rVIBE (A), pre-contrast cVIBE (B), post-contrast rVIBE (C), and post-contrast cVIBE (D) images show good -quality images for all four sequences. The pre-contrast rVIBE image again produced a smooth radiating artifact (white arrow) in the liver. VIBE: Volumetric interpolated breath-hold examination; rVIBE: Radial VIBE; cVIBE: Cartesian VIBE.
