Optocardiography and Electrophysiology Studies of Ex Vivo Langendorff-perfused Hearts
Published on: November 7, 2019
Abstract:
A method of postmortal contrast cardioventriculography on the isolated heart is presented. The cardiac ventriculi are filled with 20% barium sulphate on the gelatinous base. The roentgenologic study is made before and after the selective filling of each ventricle with contrast medium, as well as on the transversal sections of the heart, providing the possibility to assess the character of hypertrophy and dilatation, the volume and the ventricular cavities of the heart. The informative value of the method is enhanced when it is combined with the postmortem coronarography, volume-weight and planimetric cardiometry.

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...
