Gamma Knife® (radiocirugía estereotáctica) - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: Gamma Knife, también conocido como radiocirugía estereotáctica, es un tipo de tratamiento por radiación que se utiliza frecuentemente para tumores cerebrales. También puede utilizarse para otras afecciones de la cabeza. Gamma Knife es un procedimiento quirúrgico no invasivo que no requiere incisiones, cortes a través de la piel. En su lugar, una máquina se enfoca y envía con precisión alrededor de 200 haces de radiación a un área objetivo dentro de la cabeza. La radiación solo mata las células anormales sin afectar el tejido normal que se encuentra alrededor de ellas. Gamma Knife se utiliza para tratar tumores cerebrales pequeños, malformaciones en los vasos sanguíneos y afecciones nerviosas que son difíciles de alcanzar o demasiado riesgosas para tratar con otros métodos. El armazón craneal de Gamma Knife tiene cuatro clavos o tornillos. Después de adormecer el cuero cabelludo, el médico adhiere el armazón craneal con los tornillos. El armazón evita el movimiento de la cabeza y ayuda a guiar los haces de radiación. Con el armazón craneal en su lugar, se realiza un estudio por imágenes como IRM o TC para determinar el tamaño, la forma y la ubicación exactos del objetivo que debe tratarse. El equipo de tratamiento utiliza los estudios por imágenes y un software avanzado para crear un plan de tratamiento. Luego, el paciente se acuesta en la camilla de Gamma Knife. Se coloca un casco de radiación sobre el armazón craneal. El casco contiene agujeros que solo permiten el paso de la radiación programada del plan de tratamiento. Con el casco en su lugar, se desliza la camilla hacia la unidad de radiación. Este procedimiento es silencioso e indoloro. Demora entre unos minutos y una hora o más, según el tamaño y la forma del área de tratamiento. Los efectos sobre el tumor ocurren durante un período de tiempo después del procedimiento. Para obtener más información, consulte a su médico.

What attorneys say about MLA and The Doe Report:
"Whether it's demonstrating a rotator cuff tear, neck movement a few milliseconds after rear impact, or a proposed lumbar fusion, the Doe Report represents an instant on-line database of medical illustration for health-care and legal professionals.

Illustrations can be purchased 'as is' or modified within hours and sent either electronically or mounted on posterboard. An illustration is worth a thousand words, as juries perk up and look intently to capture concepts that are otherwise too abstract. Start with good illustrations, a clear and direct voice, a view of the jury as 12 medical students on day one of training, and your expert testimony becomes a pleasure, even on cross examination. An experienced trial lawyer should also emphasize these illustrations at the end of trial, as a means of visually reinforcing key concepts covered.

As a treating physician, I also use these accurate illustrations to educate my own patients about their medical conditions. The Doe Report is an invaluable resource, and its authors at MLA have always been a pleasure to work with."

"I have a medical illustration created by Medical Legal Art at the beginning of every case to tell the client's story, usually before I depose the defendant doctor. The work product and cost-efficiency are outstanding. It is a situation where, as a trial lawyer, I don't leave home without it."

"This past year, your company prepared three medical illustrations for our cases; two in which we received six figure awards; one in which we received a substantial seven figure award. I believe in large part, the amounts obtained were due to the vivid illustrations of my clients' injuries and the impact on the finder of fact."

"Thank you for the wonderful illustrations. The case resulted in a defense verdict last Friday. I know [our medical expert witness] presented some challenges for you and I appreciate how you were able to work with him."
