Spindle cell lipoma of the mediastinum: a differential consideration for liposarcoma.

Spindle cell lipoma is a benign lesion most commonly found on the posterior neck and shoulders. It shares many imaging characteristics with liposarcoma, including the presence of adipose and soft tissue elements. Although its benign nature precludes the necessity of surgical resection for treatment, surgery is often required for tissue diagnosis.

Parallel imaging of the abdomen.

Parallel imaging holds great potential for improving the quality of diagnostic abdominal MRI. The increased imaging speed afforded by parallel imaging can be translated into the obvious benefits of reduced scan time with set resolution and coverage, improved spatial resolution with set imaging time and coverage, increased anatomic coverage for a set imaging time and resolution, or some combination of the above. Additionally, the reduction in scan time can also allow some sequences that normally require multiple breath-holds to be performed with only one, or simply make breath-hold imaging possible for more patients.
