Transthoracic Needle Biopsy - Medical Animation
Your doctor may perform a transthoracic needle biopsy, or TNB, to diagnose disease in or near your lungs. The lungs are located in the chest cavity. Between the surface of the lungs and the chest wall are two layers of tissue called the pleura. One layer, the visceral pleura, is attached to the lung itself, while the other layer, the parietal pleura, is attached to the chest wall. A small amount of fluid in the pleural space, which is the space between the two layers, allows the lungs to smoothly expand and contract with each breath. Transthoracic needle biopsies may be ordered to diagnose conditions such as asthma, lung cancer, pneumonia, and chest injuries. Before your procedure, you may be given medications to suppress coughing. Your doctor may use various imaging techniques, such as a CT scan or ultrasound, to help him or her precisely locate the target of your biopsy and guide the insertion of the needle. Your skin will be cleaned at the site where the needle is to be inserted, just above one of your ribs. To help you relax you may receive a mild sedative, and a local anesthetic will be used to numb the area. A typical procedure takes less than 30 minutes. To begin, your doctor may make a small incision in your skin where the needle will be inserted. Then, while you hold your breath and remain as still as possible, your doctor will insert the needle through your skin and chest wall. You may feel pressure and then a quick, sharp pain when the needle reaches the surface of your lung. Your doctor will quickly obtain the sample of fluid or tissue and withdraw the needle. A chest x-ray or other imaging technique will be used to make sure your lung has not collapsed. The recovery time is usually very short. You will go home on the same day as the procedure unless there is a complication.

What attorneys say about MLA and The Doe Report:
"I just wanted to let you know that after several days on trial, I settled [my client's] construction accident case for $4.5 million. Immediately after the jury was discharged, I spoke with several jurors who told me that they really appreciated the medical illustrations for their clarity in dealing with [my client's] devastating injuries. They also expressed their gratitude in being able to read from a distance all of the notations without difficulty. Obviously, the boards were visually persuasive. I am certain that this contributed to our successful result."

Michael Gunzburg, Esq.
Attorney at Law.
New York, NY

"Thank you for the splendid medical-legal art work you did for us in the case of a young girl who was blinded by a bb pellet. As a result of your graphic illustrations of this tragic injury, we were able to persuade the insurance company to increase their initial offer of $75,000.00 to $475,000.00, just short of their policy limits.

We simply wanted you to know how pleased we were with your work which, to repeat, was of superlative character, and to let you know that we would be more than willing to serve as a reference in case you ever need one. Many thanks for an extraordinary and dramatic depiction of a very serious injury which clearly "catapulted" the insurance company's offer to a "full and fair" amount to settle this case."

"[Your staff] was extremely efficient, cooperative and gracious and [their] efforts produced a demonstrative exhibit that we used effectively throughout our trial. The jury verdict of $3,165,000.00 was, in no small measure, due to the impact of the demonstrative evidence. You may be sure that we will call again."

"I wanted to take some time out to let you know what a wonderful job you did with the 'collapsed lung/fractured rib' illustrations. They were both detailed and accurate. My medical expert was comfortable working with them and he spent at least an hour explaining to the jury the anatomy of the lungs, the ribs and the injuries depicted in the illustrations. Needless to say, the jury was riveted to the doctor during his testimony.

The jury returned a verdict for $800,000.00 and I'm sure we would not have done so well if not for the visualizations we were able to put forth with your assistance. Lastly, my special thanks to Alice [Senior Medical Illustrator] who stayed late on Friday night and patiently dealt with my last minute revisions."
