Percutaneous management of hepatic abscess: a perspective by interventional radiologists.

Techniques for treating hepatic abscess have evolved rapidly during the past decade. For many years, the traditional treatment was surgical drainage. The development of modern imaging modalities, such as CT and US, has not only made the diagnosis more certain, but has also introduced a variety of percutaneous treatment options.

MR angiography for preoperative evaluation of vascularized fibular grafts.

Purpose: Two magnetic resonance (MR) angiography pulse sequences, two-dimensional (2D) time of flight (TOF) and multislab three-dimensional (3D) TOF, were compared for ease of application and capability of depicting the arterial trifurcation in candidates for vascularized fibular grafts.

Patients And Methods: Both 2D TOF and multislab 3D TOF MR angiography procedures were performed to image the lower legs of 15 healthy volunteers and six patients. Three radiologists evaluated each study for the number of trifurcation vessels depicted at the knee and at the ankle, the corresponding degree of confidence, and the presence of anatomic variants.
