MR-guided neurolytic celiac plexus ablation: an evaluation of effect and injection spread pattern in cancer patients with celiac tumor infiltration.

Objective: The purpose of this study was to evaluate the feasibility, the initial accuracy, and the effects of the MR-guided neurolytic celiac plexus ablation as a method to treat cancer-induced chronic abdominal pain.

Methods: Thirteen celiac plexus ablations were performed for 12 patients. A 0.

Liver tumor laser ablation - increase in the subacute ablation lesion volume detected with post procedural MRI.

Background: The use of image-guided thermoablative methods in liver tumor treatment has expanded rapidly due to encouraging results and advanced imaging. However, little is known about the treatment-induced tissue response and effects on imaging findings during the subacute post procedural period.

Purpose: To study the development of subacute ablation zone volume with magnetic resonance imaging (MRI) after laser-mediated liver tumor thermal therapy.

MRI-guided percutaneous laser ablation of small renal cell carcinoma: Initial clinical experience.

Background: The number of detected small renal cell carcinomas (RCCs) has been rising, largely due to advances in imaging. Open surgical resection is the standard management of small RCCs; however, imaging-guided percutaneous ablative therapies have emerged as a minimally invasive treatment alternative, especially for patients who are poor candidates for surgery.

Purpose: To evaluate the initial clinical experience of magnetic resonance imaging (MRI)-guided percutaneous laser ablation of small RCCs.

MRI-guided percutaneous nephrostomy: a feasibility study.

The purpose of this study was to assess the feasibility and safety of magnetic resonance imaging (MRI)-guided PCN in an open-configuration low-field MRI system. Eight patients were prospectively enrolled in the study. The degree of the dilatation of the renal collecting system varied from minimal to severe.

Feasibility of MR imaging-guided percutaneous drainage of pancreatic fluid collections.

Purpose: To assess the feasibility and safety of magnetic resonance (MR) imaging-guided percutaneous drainage of pancreatic fluid collections in an open configuration low field MR imaging system.

Materials And Methods: Ten patients with pancreatic fluid collections were examined prospectively. Five of the fluid collections were symptomatic pseudocysts and five were pancreatic abscesses.

Arterial embolization and prophylactic catheterization for the treatment for severe obstetric hemorrhage*.

Background: To evaluate indications, efficacy, and complications associated with arterial embolization and prophylactic balloon catheterization in the management of obstetric hemorrhage at a university hospital.

Methods: Twenty-two women underwent arterial embolization between February 2001 and November 2003 for the treatment for primary postpartum hemorrhage resulting from abnormal placentation (n=11), uterine atony (n=7), paravaginal laceration (n=3), and disseminated intravascular coagulopathy (n=1). Blood loss was between 3.

Interventional and intraoperative MRI at low field scanner--a review.

Magnetic resonance imaging (MRI) is a cutting edge imaging modality in detecting diseases and pathologic tissue. The superior soft tissue contrast in MRI allows better definition of the pathology. MRI is increasingly used for guiding, monitoring and controlling percutaneous procedures and surgery.
