Anatomical MR imaging of long bones: Comparative performance of MRI at 1.5 T and 3 T

Cardiovascular MR imaging at 3 T: opportunities, challenges, and solutions.

Although 3-T magnetic resonance (MR) imaging is well established in neuroradiology and musculoskeletal imaging, it is in the nascent stages in cardiovascular imaging applications, and there is limited literature on this topic. The primary advantage of 3 T over 1.5 T is a higher signal-to-noise ratio (SNR), which can be used as such or traded off to improve spatial or temporal resolution and dec...

MR Diagnosis of Bone Metastases at 1.5 T and 3 T: Can STIR Imaging Be Omitted?

OBJECTIVE To date, no prospective comparative study of the diagnostic value of STIR versus T1-weighted (T1w) sequences at both 1.5 T and 3 T has been performed with special focus on the detectability of bone metastases. MATERIALS AND METHODS 212 oncological patients had a whole-body MRI at 1.5 T and/or at 3 T. The standard protocol comprised STIR and T1w sequences. All patients who showed typ...

In vivo Mr imaging at 21.1 T

In vivo magnetic resonance (Mr) imaging and spectroscopy are expanding our capability to observe and investigate many biomedical processes without invasive interventions. The unique 900-Mhz ultra-wide bore (uWB) 21.1 tesla magnet built at the Magnet lab in Tallahassee provides unprecedented opportunities to examine living systems. in this report, we present our first experiences and the results...

Comparison of conventional 3-T MRI and 1.5-T MR arthrography of femoroacetabular impingement (FAI)

Cardiovascular MRI at 3 T & Beyond

In recent years the high and ultra-high magnetic field MRI scanners have started to leave the confinement of specialized and research oriented laboratories and progressively are entering the clinical use. There are several reasons to justify the progressive increase of the field such as better quality of images that is better spatial resolution, better signal to noise and contrast to noise rati...
