Abstract:
The results of planar perfusion scintigraphy, SPECT and CT were evaluated quantitatively and compared with each other in 47 patients with thoracic tumours. SPECT was superior to conventional scintigraphy in respect of morphological information. Quantitative evaluation of the function data derived from SPECT permits a more detailed anatomical recognition of perfusion inhomogeneity due to the tumour and can distinguish between central and peripheral tumour growth. Comparison between CT and SPECT showed good morphological agreement between the two.

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...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
