Figure 10: (10a) A GRE T2*-weighted sagittal image reveals a complex tear of the posterior horn of the medial meniscus, having horizontal (arrows) and longitudinal (arrowhead) components. Complex tears like this are likely to be unstable.igure 6: (6a) A radial tear of the body of the lateral meniscus also appears vertical on sagittal MR images (arrow), though in the case of radial tears, the lesion is oriented perpendicular to the c-shaped fibers of the meniscus.
In brief: See a doctor, urgent. A collapsed lung (pneumothorax) is due to an air leak from the inside of the lung through the covering of the lung, out into the space between the lung and the ribs. The site of the leak has some damage, which will heal itself later.
Respiratory failure happens when not enough oxygen passes from your lungs into your blood. Your body's organs, such as your heart and brain, need oxygen-rich blood to work well. Respiratory failure also can happen if your lungs can't remove carbon dioxide (a waste gas) from your blood. Too much carbon dioxide in your blood can harm your body's organs. Diseases and conditions that affect your breathing can cause respiratory failure. Examples include. Lung diseases such as COPD (chronic obstructive pulmonary disease), pneumonia, pulmonary embolism, and cystic fibrosis.
