Jabi E. Shriki MD, Presenter: Nothing to Disclose

The following teaching points will be emphasized: Minimum intensity projection (MinIP) reformatting is a technique for depicting low attenuation or low signal intensity structures within a volume of tissue. This technique has particular utility in thoracic imaging in depicting a wide range of pathology, and can be applied to CT or MRI. MinIP is commonly useful in depicting airways in order to show normal bronchi, variants of normal anatomy, and pathological conditions affecting the airways. Normal and variant anatomy and disease states of the bronchi will be reviewed. MinIP is also useful in evaluating the pulmonary parenchyma in demonstrating areas of lucency or low signal intensity, which can either be due to air trapping or decreased perfusion. Various diseases which can result in oligemia or air trapping will be discussed. MinIP can also be used to demonstrate other structures which are low in signal intensity or attenuation within a background of hyperattenuation or high signal, such as dissection flaps within a contrast-filled lumen.

Techniques for MinIP reformatting of imaging studies: the basics of MinIP. MinIP in the depiction of the airways. MinIP in the evaluation of the lung parenchyma. MinIP for demonstration of low attenuation or low signal intensity structures within a "bright" background.
