Image-guided tumor ablation: standardization of terminology and reporting criteria--a 10-year update.

Image-guided tumor ablation has become a well-established hallmark of local cancer therapy. The breadth of options available in this growing field increases the need for standardization of terminology and reporting criteria to facilitate effective communication of ideas and appropriate comparison among treatments that use different technologies, such as chemical (eg, ethanol or acetic acid) ablation, thermal therapies (eg, radiofrequency, laser, microwave, focused ultrasound, and cryoablation) and newer ablative modalities such as irreversible electroporation. This updated consensus document provides a framework that will facilitate the clearest communication among investigators regarding ablative technologies.

Magnetic resonance-guided focused ultrasound for patients with painful bone metastases: phase III trial results.

Background: Pain due to bone metastases is a common cause of cancer-related morbidity, with few options available for patients refractory to medical therapies and who do not respond to radiation therapy. This study assessed the safety and efficacy of magnetic resonance-guided focused ultrasound surgery (MRgFUS), a noninvasive method of thermal tissue ablation for palliation of pain due to bone metastases.

Methods: Patients with painful bone metastases were randomly assigned 3:1 to receive MRgFUS sonication or placebo.

Pain palliation in patients with bone metastases using MR-guided focused ultrasound surgery: a multicenter study.

Background: Noninvasive thermal ablation using magnetic resonance (MR)-guided focused ultrasound (MRgFUS) has been shown to be clinically effective in uterine fibroids, and is being evaluated for ablation of breast, liver, and brain lesions. Recently MRgFUS has been evaluated for palliation of pain caused by bone metastases. We present the clinical results of a multicenter study using MRgFUS for palliation of bone metastases pain.

Palliative treatment of painful bone metastases with MR imaging--guided focused ultrasound.

Purpose: To evaluate the safety and initial efficacy of magnetic resonance (MR) imaging-guided focused ultrasound for the palliation of pain caused by bone metastases in patients in whom standard available treatments had been ineffective or not feasible.

Materials And Methods: Informed consent was obtained in 11 patients (seven women, four men; average age, 58.6 years) with pain related to non-weight-bearing bone metastases who were subsequently treated with MR imaging-guided focused ultrasound in this research and ethics board-approved study.

Chest tube drainage under radiological guidance for pleural effusion and pneumothorax in a tertiary care university teaching hospital: Review of 51 cases.

Background: Chest tube drainage under radiological guidance has been used with increasing frequency as a treatment option for pleural effusions and pneumothoraxes.

Objective: To evaluate the safety and usefulness of pleural drainage under radiological guidance for pleural effusion and pneumothorax in a tertiary care university teaching hospital.

Methods: A retrospective study of cases of chest tube placement under radiological guidance over a 12-month period in a university hospital.

MR imaging-guided focused ultrasound surgery of breast cancer: correlation of dynamic contrast-enhanced MRI with histopathologic findings.

Purpose: To assess the value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameters to monitor residual tumor following non-invasive MRI-guided focused ultrasound surgery (MRIgFUS) of breast tumors.

Methods: DCE-MRI data were acquired before and after the MRIgFUS treatment of small breast tumors (d < 3.5 cm) for 17 patients.

Feasibility of magnetic resonance imaging-guided focused ultrasound surgery as an adjunct to tamoxifen therapy in high-risk surgical patients with breast carcinoma.

Purpose: To evaluate the feasibility of treating breast neoplasms with use of magnetic resonance (MR) imaging-guided focused ultrasound (US) surgery.

Materials And Methods: Twenty-four female patients, each with a single biopsy-proven breast carcinoma, who were considered to be at increased surgical risk or who had refused surgery underwent MR imaging-guided focused US surgery as an adjunct to their chemotherapeutic regimen of tamoxifen. Follow-up included routine studies to rule out metastatic disease and MR studies with and without contrast material infusion in the treated breast (10 days and 1, 3, and 6 months after the treatment session).

MR imaging-guided focused US ablation of breast cancer: histopathologic assessment of effectiveness-- initial experience.

Purpose: To evaluate the effectiveness of noninvasive magnetic resonance (MR) imaging-guided focused ultrasonographic (US) ablation of breast carcinomas.

Materials And Methods: Before undergoing tumor resection, 12 patients with invasive breast carcinomas were treated with MR imaging-guided focused US ablation consisting of multiple sonications of targeted points that were monitored with temperature-sensitive MR imaging. The patients were treated with either one of two focused US systems.

Helical CT with CT angiography in assessing periampullary neoplasms: identification of vascular invasion.

Purpose: To determine the accuracy of helical computed tomography (CT) with CT angiography in identifying vascular invasion by periampullary neoplasms and to assess the added value of CT angiography.

Materials And Methods: Sixty-nine patients suspected of having periampullary neoplasms were examined. Images from dual phase helical CT with CT angiography were compared with surgical findings in 36 patients.
