Abstract:

In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we have not a good prognosis in metastatic tumors but post-operative follow up and brain CT scan established the effect of laser on resection and evaporation and diminution of mass effect in tumor lesions.

Non-Rigid Registration of Liver CT Images for CT-Guided Ablation of Liver Tumors

CT-guided percutaneous ablation for liver cancer treatment is a relevant technique for patients not eligible for surgery and with tumors that are inconspicuous on US imaging. The lack of real-time imaging and the use of a limited amount of CT contrast agent make targeting the tumor with the needle challenging. In this study, we evaluate a registration framework that allows the integration of di...

Preliminary experience with MR-guided thermal ablation of brain tumors.

PURPOSE To evaluate the feasibility of a technique of MR-guided stereotactic radio frequency ablation, which was developed as a minimally invasive treatment for brain tumors, and to determine MR characteristics and sequential evolution of radio frequency lesions created to ablate brain tumors. METHODS Fourteen lesions in 12 patients with primary and metastatic brain tumors were treated with t...

PET and MRI-guided focused ultrasound surgery for hypoxic-tissue ablation combined with radiotherapy in solid tumors

Background: The rationale was to develop an ablation approach to destroy regions of tumor resistant to radiation and thus reduce the time required for whole tumor ablation, while improving overall tumor control after radiotherapy. Materials and Methods: The system is composed of a micro positron emission tomography (mPET), 7T magnetic resonance imaging (MRI), and a customized MRI-compatible foc...

Image-Guided Percutaneous Ablation of Renal Tumors

Renal tumors account for more than 50,000 new cases annually in the United States with a rising incidence (Chow et al., 1999). This is mainly because of an increase in diagnosis due to widespread use of cross-sectional imaging (Pantuck et al., 2001). Renal cell carcinoma constitutes 4% of all adult malignancies (American Cancer Society, 2008) and about 70 to 80 percent of patients presenting wi...

CT-guided microwave ablation through the lungs for treating liver tumors near the diaphragm

Purpose To explore the short-term efficacy and safety of CT-guided microwave ablation (MWA) for treating liver tumors near the diaphragm. Results The complete response (CR) rate for CT-guided MWA through the lung was 94.7% (124/131). The incomplete response (ICR) rate was 5.3% (7/131), of which 6 patients with ICRs achieved CRs after MWA. The CR rate for Group I was higher than Group II (99.0...
