MR imaging without and with gadolinium-based contrast agents (GBCAs) is an important imaging tool for defining normal anatomy and characteristics of lesions. GBCAs have been used in contrast-enhanced MR imaging…
Since their introduction, gadolinium-based contrast media are routinely used in most CNS MR imaging indications. Due to their paramagnetic effect, they significantly shorten the T1 relaxation times of the tissue…
There has been much progress in contrast enhanced neuroradiologic magnetic resonance imaging in the almost 25 years since the first gadolinium-based contrast agent was approved in the United States. Much…
Magnetic resonance (MR) imaging has become the workhorse in the imaging evaluation of the painful or clinically abnormal hip. It provides an excellent anatomic overview and demonstration of the bony…
MR imaging of the hip is frequently used in symptomatic patients before hip preservation surgery; it is used as a decision-making tool and as a planning tool. The MRI can…
After initial evaluation with radiography, magnetic resonance (MR) imaging is the most common modality used to establish the diagnosis and characterize osseous and soft tissue tumors of the hip. Tumors…
Metal-on-metal (MoM) hip arthroplasty was expected to provide benefits over metal-on-polyethylene systems. After widespread placement of MoM implants, outcomes have been disappointing. MoM implants are associated with higher serum levels…
Inflammation of the hip may be due to infectious and noninfectious causes. Furthermore, involvement is categorized based on the origin and spread to adjacent structures involving the soft tissues, the…
Magnetic resonance imaging (MRI) has become the standard imaging modality for activity-related groin pain. Lesions, including rectus abdominis/adductor aponeurosis injury and osteitis pubis, can be accurately identified and delineated in…
MR imaging, because of its multiplanar capability and superior soft tissue contrast resolution, is the preferred modality to assess osseous and soft tissue structures around the hip joint. This article…
