Lung Capacity01:47

Lung Capacity

56.4K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Pleura of the Lungs01:13

Pleura of the Lungs

7.6K
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Gross Anatomy of the Lungs

The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

Cancer02:18

Cancer

54.5K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?

14.5K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Cancer Vaccines01:30

Cancer Vaccines

1.1K
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

  • Radiology
  • Thoracic Surgery

Background:

  • National lung screening programs and increased CT use identify more indeterminate pulmonary nodules.
  • Biomarker-driven therapies increase the need for repeat percutaneous transthoracic needle biopsies (PTNB).
  • Preoperative nodule localization with markers facilitates minimally invasive surgery and radiation planning.

Purpose of the Study:

  • To discuss the technique and applications of image-guided percutaneous transthoracic needle biopsy (PTNB).
  • To outline patient selection criteria for PTNB.
  • To review biopsy techniques and complication management.

Main Methods:

  • Image-guided percutaneous transthoracic needle biopsy (PTNB) is described.
  • Patient selection and biopsy techniques are discussed.
  • Minimizing and managing complications are reviewed.

Main Results:

  • PTNB is a well-established technique for pulmonary nodule evaluation.
  • PTNB is crucial for diagnosis, repeat biopsies, and preoperative localization.
  • Effective complication management is essential for PTNB.

Conclusions:

  • Image-guided PTNB is a vital tool for diagnosing and managing pulmonary nodules.
  • The technique supports lung cancer treatment through accurate tissue sampling and localization.
