Radionuclide localization of massive pulmonary hemorrhage
Abstract:
Lung scans with technetium sulfur colloid were performed in ten patients with life-threatening hemoptysis and nondiagnostic chest roentgenograms. Localized deposition of radionuclide was demonstrated in five of the six patients who were studied during active bleeding. These abnormalities were confirmed bronchoscopically in four patients, and lung scans provided clinically useful information regarding the bleeding site that had not been available from the medical history, physical examination, or chest roentgenogram. Evaluation with radionuclide scanning may complement bronchoscopic and roentgenographic studies in selected patients with massive pulmonary hemorrhage.

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...
