Dynamic studies with radionuclides.
Scintigraphy, the visual display of radioactivity, shows the size, shape and structure of the organ being studied. This information should be complemented with dynamic studies which will indicate the distribution of the radioactivity in the organ in relation to time. Dynamic studies must be performed with external detectors and the gamma camera. Circulation (systemic, pulmonary or cerebrospinal fluid) can be studied depending on the method of administration and the radionuclide used. The indicators are the same as for arteriography. Regional distribution of ventilation can be studied using radioactive gases. Regional distribution of ventilation of the lungs and mucociliary clearance can also be studied using inhaled particles. Dynamic studies do not replace but only supplement scintigraphy. They should be quantitated to obtain objective information.
