This article illustrates changes in the underlying physics concepts related to increasing the
main magnetic field from 1.5 T to 3T. The effects of these changes on tissue constants and …

OBJECTIVE. MRI is the most accurate noninvasive method available to diagnose disorders
of articular cartilage. Conventional 2D and 3D approaches show changes in cartilage …

Balanced steady‐state free precession (SSFP) techniques provide excellent contrast
between myocardium and blood at a high signal‐to‐noise ratio (SNR). Hence, SSFP …

Gradient‐echo sequences are widely used in magnetic resonance imaging (MRI) for
numerous applications ranging from angiography to perfusion to functional MRI. Compared …

Refocused steady‐state free precession (SSFP) imaging sequences have recently regained
popularity as faster gradient hardware has allowed shorter repetition times, thereby reducing …

Refocused steady‐state free precession (SSFP) is limited by its high sensitivity to local field
variation, particularly at high field strengths or the long repetition times (TRs) necessary for …

Balanced steady‐state free precession (SSFP) imaging sequences require short repetition
times (TRs) to avoid off‐resonance artifacts. The use of slab‐selective excitations is …

Fetal and neonatal MR imaging is increasingly used as a complementary diagnostic tool to
sonography. MR imaging is an ideal technique for imaging fetuses and neonates because of …

Magnetic resonance (MR) imaging is finding an ever-growing role in the evaluation of a
wide range of conditions in the abdomen. No longer confined to problem solving regarding …

Background—Magnetic resonance (MR)–guided coronary artery stent placement is a
challenging vascular intervention because of the small size of the coronary arteries …
