Dynamic Sequential MR Imaging of Focal Liver Lesions

Dynamic enhancement of upper abdominal organs in normal volunteers with MRI and effects of contrast dose reduction

“…These numbers differ from those reported by Hammed et al [9], but in their protocol, scanning was repeated only every 30 s during the first 2 min and then every 60 s for up to 10 min. In the present study, peak liver enhancement occurred approximately 50 s after injection, and this was comparable to the results reported by Shmiedl et al [10]. In fact, liver enhancement is mainly dependent on portal vascularization.…”

Correlation of three-dimensional gradient echo dynamic MR imaging with CT during hepatic arteriography in patients with hypervascular hepatocellular carcinomas: Preliminary clinical experience

“…Index terms: magnetic resonance; contrast enhancement; liver neoplasm; three-dimensional image; dynamic study THE VALUE OF DYNAMIC MAGNETIC RESONANCE (MR) imaging has been reported for the diagnosis of liver tumors, particularly hepatocellular carcinomas (HCC) (1)(2)(3)(4)(5)(6)(7)(8)(9). Stress has been imposed on the importance of detecting early enhancement of the tumors which would represent their hypervascularity as observed on angiography (7)(8)(9).…”

Contrast enhancement of the gastrointestinal tract on MR images using intravenous gadolinium-DTPA

“…Intravenous contrast enhancement does not have the detrimental effect of increasing peristaltic motion which may occur with oral contrast, particularly when osmotic agents are also used. Intravenous administration of gadopentetate dimeglumine has established a proven safety record over a considerable time period [15], and it also provides enhancement of other abdominal viscera which has been found to improve detection of a variety of pathologic conditions throughout the abdomen [16][17][18][19].…”
