[Computerized tomography studies in the assessment of radiogenic pneumopathy in an animal experiment]
Abstract:
An animal experimental study was conducted in 56 piglets exposed to radiation to establish new assessment criteria on radiogenic pneumopathy by employing computed tomography for diagnosis. The accurately measurable density changes in the lung parenchyma exposed to radiation appear invariably as soon as a dose-dependent threshold value is exceeded. Tolerance limits can be determined for 60Co and neutron irradiation in different fractions and single doses, the enhancement of lung density being correlated with the irradiation dose. It is not possible to establish a volume-dependent decrease in the tolerance dose. Likewise, there is no radiation-promoted co-reaction of adjacent pulmonary tissue not subjected to irradiation exposure. These results apply to the experimental animals used in the study.

Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
