RESUMO
Computed tomography (CT) has proven useful in diagnosing inflammatory and neoplastic disease of the pancreas. Neoplasms of the pancreas produce enlargement of the gland and loss of surrounding fat planes. Acute pancreatitis also produces enlargement but correct diagnosis can be made with the clinical correlation. The usefulness of CT in chronic pancreatitis depends upon the state of the disease. Distinction between an inflammatory and a neoplastic mass is not possible on the basis of a CT scan alone. CT is also useful for needle guidance for aspiration biopsy of the pancreas.

Total body computed tomography has introduced a unique method of obtaining body contours as well as anatomical representations for radiation therapy treatment planning. CT scanning combined with computerized radiation therapy treatment planning has improved accuracy and contributed greatly to the solution of complex treatment problems. CT scans can also be used to evaluate the progress of patients undergoing radiation therapy.

In this treatment planning method, information from total body scans is fed into a radiation therapy treatment computer, the Artronix PC-12 system with 16K core. By providing an accurate profile of the patients's anatomy, total body computed tomography may contribute greatly to the solution of complex treatment problems involving the head and neck, thorax and abdomen.

Lung scanning is a safe and simple procedure which, when correlated with chest roentgenograms and clinical picture, is a valuable tool in diagnosing pulmonary embolism. Pulmonary arteriography is a valuable diagnostic procedure and should be employed when serious doubt exists as to the presence or absence of pulmonary emboli. It should also be used whenever surgical treatment is under consideration.
