摘要:

To interpret mediastinal abnormalities, an understanding of the reflections produced by the various areas of lung in contact with the mediastinum is mandatory. In this prsentation many of the normal mediastinal reflections are reviewed and correlated with anatomic and CT demonstrations. Emphasis is placed on the similarities and dissimilarities of these reflections and their relationships to mediastinal structures or coronal mediastinal planes. Abnormal examples of these reflections are included, as well as the frequency with which the normal reflections may be seen.

摘要:

Refinements of computer software permit electronic reconstructions of CT sagittal, parasagittal, and coronal planes, which have markedly improved our understanding of the relations among mediastinal structures, most of which present a vertical course, as well as between focal lesions and adjoining structures.

摘要:

A determination of the anatomic extent of tumor is important in planning appropriate invasive diagnostic procedures and treatment in patients with bronchogenic carcinoma. In most situations, plain radiographs provide useful anatomic information, but CT is necessary for detailed evaluation. Although some plain film and CT findings strongly suggest that a tumor is unresectable, they are usually nonspecific, and biopsy correlation is necessary before the patient is denied an attempt at a surgical cure. Also, in the light of recent advances in the surgical treatment of lung cancer, some lesions formerly thought to be unresectable because of local or regional metastases are being effectively treated. Close communication between the radiologist and surgeon is necessary in the appropriate management of these patients.

摘要:

The mediastinum is commonly involved with disase in patients with Hodgkin's and non-Hodgkin's lymphomas. The involvement may be permeative, or individual groups of nodes may be enlarged. The parietal nodes of the mediastinum may also be abnomal with either type.Precise mapping of all disease is important when radiation therapy is to be a major component of treatment planning.Detection of relapse following mantle irradiation is frequently dependent on having a new comparative baseline after the distortions of mediastinal contours consequent to radiation treatment have stabilized.

摘要:

Which imaging procedure is best for the diagnosis of the superior vena cava (SVC) syndrome is subject to considerable debate. Available imaging procedures include the plain chest film. SVC phelbography, scintiangiography, digital phlebography, CT digital phlebography, and CT. In our experience the combined technique of contrast CT axial images, followed by a CT digital phlebogram, is the most infomative, cost-effective, and least invasive method available.

摘要:

Acute mediastinal diseases most often result from penetrating or blunt trauma and from iatrogenic injuries related to the misplacement of tubes and catheters. The commonest chest film findings of mediastinal disease include mediastinal contour alteration, such as obliteration of normal structures mediastinal widening, and pneumomediastinum. Characteristic mediastinal findings injury to specific mediastinal structures are presented.
