PURPOSE To retrospectively evaluate a respiratory-triggered diffusion-weighted (DW) magnetic resonance (MR) imaging sequence combined with parallel acquisition to allow the calculation of pure molecular-based (D) and perfusion-related (D*, f) diffusion parameters, on the basis of the intravoxel incoherent motion (IVIM) theory, to determine if these(More)
BACKGROUND Real-time 3-dimensional echocardiography (RT3DE) is superior to 2D echocardiography in assessing left ventricular (LV) volumes and ejection fraction (EF), but its feasibility is limited by multibeat acquisition, which requires an optimal breath-hold and a regular heart rhythm. We sought to evaluate the accuracy and feasibility of single- and(More)
To evaluate both in vivo and in phantom studies, dose reduction, and image quality of body CT reconstructed with model-based iterative reconstruction (MBIR), performed during patient follow-ups for lymphoma. This study included 40 patients (mean age 49 years) with lymphoma. All underwent reduced-dose CT during follow-up, reconstructed using MBIR or 50 %(More)
OBJECTIVE This study was to determine the long-term outcomes of arterial pelvic embolization for intractable postpartum hemorrhage and particularly its effect on menses, fertility, and outcomes of subsequent pregnancies. STUDY DESIGN Fifty-six consecutive patients who underwent emergency pelvic arterial embolization for severe postpartum hemorrhage(More)
PURPOSE To determine if intra-voxel incoherent motion diffusion-weighted imaging (IVIM-DWI) parameters, including free molecular-based (D) and perfusion-related (D*, f) diffusion parameters, correlate with the degree of tumor necrosis and viable tumor in colo-rectal cancer (CRC) metastasis. MATERIALS AND METHODS Fifteen patients referred for resection of(More)
RATIONALE The pathophysiology of acute chest syndrome (ACS) in patients with sickle cell disease is complex, and pulmonary artery thrombosis (PT) may contribute to this complication. OBJECTIVES To evaluate the prevalence of PT during ACS using multidetector computed tomography (MDCT). METHODS We screened 125 consecutive patients during 144 ACS episodes.(More)
OBJECTIVE MRI has become the primary tool for assessment of myocardial inflammation in patients with suspected acute myocarditis. Optimal diagnostic performance is achieved with late gadolinium-enhanced sequences, but cine balanced steady-state free precession (SSFP) MRI sequences are routinely used to evaluate cardiac function. Our aim was to prospectively(More)
OBJECTIVES The aim of this study was to compare left ventricular longitudinal strain (LS) evaluated by 2-dimensional echocardiography with cardiac magnetic resonance (CMR) in cardiac amyloidosis (CA), establish correlations between histological and imaging findings, and assess the prognostic usefulness of LS measurement and CMR. BACKGROUND CA is a(More)
Understanding the levator ani complex architecture is of major clinical relevance. The aim of this study was to determine the feasibility of magnetic resonance (MR) fiber tractography with diffusion tensor imaging (DTI) as a tool for the three-dimensional (3D) representation of normal subdivisions of the levator ani. Ten young nulliparous female volunteers(More)
OBJECTIVE FDG PET has been recognized as an efficient imaging technique for the treatment of oncology patients. However, false-positive results can occur. The purpose of this study is to describe three oncology patients with persistent FDG up-take around inguinal mesh prostheses that occurred up to 10 years after the surgical repair of inguinal hernias and(More)
