Computerized tomography in the assessment of diseases of the thorax: a critical review.

Many diseases of the chest wall, heart, mediastinum, pleura, and lungs can be successfully imaged by CT. Radiotherapy ports can be calculated and transcutaneous biopsies can be monitored. In future, it is conceivable that by studying the numerical data within these areas of diseased and healthy lung it may be possible to more closely correlate pulmonary function with radiographic images. It is hoped that lung volumes extravascular lung water, blood flow patterns, and many more physiological parameters may become open to elucidation by CT.

Computerized tomography in the assessment of diseases of the thorax.

Many of the diseases of the chest wall, heart, mediastinum, pleura and lungs can be successfully imaged by computerized tomography. Radiation therapy ports can be calculated and transcutaneous biopsies monitored. This paper deals with the many uses that we have had for computerized tomography in assessing diseases within the chest and thorax.

Computerized tomography in pulmonary sarcoidosis.

Six patients with documented pulmonary sarcoidosis were selectively studied with the ACTA scanner. The CT scans were correlated with the standard chest radiographs of these patients. CT scans readily confirmed adenopathy, calcification, and pleural disease. Likewise, diffuse and isolated parenchymal disease was detected and in some cases unexpected lung involvement was noted.

Direct coronal computerized tomography.

The computerized tomographic examination is routinely performed in the axial plane. However, with several available CT units images in the coronal plane are easily obtained. These images are especially useful in the diagnosis of diseases of the facial bones, sinuses, orbits and parasellar area. This paper describes one year's clinical experience with direct coronal computerized tomography.

The radiology of transsphenoidal hypophysectomy: a review of 100 cases.

This report describing the radiology of transsphenoidal hypophysectomy based on a review of 100 consecutive surgical procedures. Preoperative laminographic evaluation of the sphenoid sinus is an important aid in planning the most direct surgical approach to the pituitary. It is also useful in defining the many anatomic structures that may be injured inadvertently at the time of surgery. Intraoperative radiography or fluoroscopy is helpful in identifying the sella floor and as an aid in preventing loss of orientation within a capacious sinus. Various changes occur within the sphenoid sinus following surgery, some transient and others persistent. The surgical defect is usually difficult to identify on routine roentgenograms but is clearly visible on lateral laminography. A persistent soft tissue mass within the sinus is usually a manifestation of fascia and fat placed as a seal within the sinus.

Preoperative laminagraphic evaluation of the sphenoid sinus for transsphenoidal surgery.

In recent years the transethmoidal and transnasal approaches to the pituitary gland have become increasingly popular. In each case, detailed preoperative analysis of the anatomy of the sphenoid sinus and its boundaries is crucial in facilitating entry to the pituitary fossa and in reducing intraoperative complications. Certain operative difficulties and complications are the result of the marked variability in the anatomy of the sphenoid bone and its sinus. These include: loss of orientation within a capacious sinus; perforation of the carotid artery or cavernous sinus; injury to the optic nerve or ophthalmic artery; and violation of the subarachnoid space with resultant pneumocephalus or cerebrospinal fluid rhinorrhea. Pneumatization develops originally within the presphenoid, beginning anteriorly and proceeding posteriorly. Around the time of puberty the pneumatization usually penetrates up to the spheno-occipital synchondrosis. Dense bony septa remain within the sinus along the plane of fusion of the various sphenoidal segments. Preoperative laminagraphy of these ridges and septa is extremely helpful in planning the safest and most direct route to the sella. Laminagraphy is preferable to routine skull films because the septal detail is unobscured by overlying facial structures. Pleuridirectional laminagraphic motion (circular or hypocycloidal) is preferred to linear motion because of the clarity and detail that they provide.
