• Analysis of clinical workflow improvements in abdominal MRI.
• Case examples illustrating the benefits in specific applications.

Main Results:

• Breath-hold imaging for liver lesions (detection, characterization, biopsy) is now more practical.
• MR cholangiopancreatography (MRCP) acquisition times have been reduced.
• Chemical shift imaging (liver, adrenal glands) is more robust and faster.
• Dynamic imaging following contrast media injection offers improved temporal resolution.
• MR angiography (MRA) benefits from faster scan times and reduced motion artifacts.

Conclusions:

• Increased MRI efficiency has revolutionized abdominal imaging.
• These advancements enable more comprehensive and faster patient examinations.
• Future developments will likely further enhance diagnostic capabilities in abdominal MRI.
