T2-Weighted Liver MRI Using the MultiVane Technique at 3T: Comparison with Conventional T2-Weighted MRI

T2-Weighted Liver MRI Using the MultiVane Technique at 3T: Comparison with Conventional T2-Weighted MRI

OBJECTIVE To assess the value of applying MultiVane to liver T2-weighted imaging (T2WI) compared with conventional T2WIs with emphasis on detection of focal liver lesions. MATERIALS AND METHODS Seventy-eight patients (43 men and 35 women) with 86 hepatic lesions and 20 pancreatico-biliary diseases underwent MRI including T2WIs acquired using breath-hold (BH), respiratory-triggered (RT), and M...

T2-weighted Liver Mri at 3t Using a Blade Technique: Comparison with a Standard Rectilinear T2-weighted Sequence for Image Quality and Lesion Detection

Introduction: The quality of T2-weighted images (T2WI) of the liver in the clinical setting is often degraded by ghosting artifact from various sources of motion. This artifact can obscure the margins of the liver, intra-hepatic vessels, and focal liver lesions, lowering diagnostic utility. One study has noted that such motion within the liver is more severe at 3T compared with at 1.5T [1]. Fur...

T2*-weighted MRI technique for visualization of RF ablation lesions

Background LGE-MRI is widely used to assess cardiac RF ablation lesions. However, LGE-MRI requires contrast injection and the appearance, dimensions and visibility of lesions in LGE-MRI noticeably change with time after ablation and time after contrast injection. Recently proposed non-contrast T1-weighted (T1w) technique is only applicable to visualize acute (< 3 days) RF lesions. The main goal...

Myocardial Edema on T2-Weighted MRI

Importance of Evaluation of Ischemia/ Reperfusion Injury by Magnetic Resonance Imaging Although the advances in revascularization therapy have drastically decreased the mortality after ST-segment–elevation myocardial infarction (STEMI), the number of patients who develop heart failure after the reperfusion therapy continues to increase. More than 30% of the patients who survive STEMI develop he...
