Abstract:
The purpose of this study is to compare contrast-enhanced three-dimensional (3D) magnetic resonance (MR) portograms to Doppler sonography in detection of portal venous abnormalities. Thirty-five consecutive patients, who were suspected of having portal venous system abnormalities, were examined with MR portography and Doppler sonography. Vascular abnormalities were identified in 27 of 35 patients. There was statistically significant agreement between the results of MR portography and Doppler sonography. The major limitation of contrast-enhanced 3D MR portography was its inability to provide objective hemodynamic data regarding flow direction and flow pattern.

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...
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...
