MRI-guided ultrasound therapy relieves symptoms in patients with uterine fibroids

01.12.2004


Also helps some patients avoid hysterectomy



MRI-guided ultrasound therapy is an effective way to treat women with uterine fibroids, improving their quality of life and avoiding hysterectomy, a new study shows. The study reviewed the use of MRI and the ExAblate 2000, a device that was recently approved by the Food and Drug Administration.

About 25% of women have uterine fibroids with a substantial proportion of these experiencing symptoms, said Dr. Wladyslaw Gedroyc of St. Mary’s Hospital and the Imperial College School of Medicine in London. These symptoms include abdominal pain, bladder irritability and menstrual irregularities, he said. These patients are commonly treated with surgery. However, "our study of 109 patients found that combining MRI and ultrasound can be a viable alternative to a hysterectomy or myomectomy."


Patients in the study answered a quality of life questionnaire before then after the MRI-ultrasound procedure. "Overall there was a significant improvement in the quality of life scores in 80% of the patients," six months following the procedure, said Dr. Gedroyc. He added that updated results are being analyzed, but "at 12 months post procedure the improvements and changes are predominately maintained."

The procedure includes using MRI to plan the treatment and guide the treatment as it is being done. Focused ultrasound destroys the fibroid tissue. The procedure is "completely non-invasive and can be done as an outpatient procedure. In addition the whole process is very safe with very few side effects," Dr. Gedroyc said. One patient had sciatic nerve damage with pain and mild weakness, but this resolved itself quickly. One patient was kept overnight because she had a reaction to the sedation she was given, Dr. Gedroyc said. "There were several instances where patients had prolonged menstrual bleeding, but this was not any different than what they had experienced before the procedure so this was probably secondary to the underlying problem rather than a result of the treatment," he said.

The success of this procedure in treating uterine fibroids might be just the beginning, said Dr. Gedroyc. "It points the way forward to the utilization of this technology in other areas such as the treatment of solid organ malignancies," he said.

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
