Imaging of the portacaval space
Abstract:
The portacaval space is a relatively narrow region between the portal vein and the inferior vena cava that is usually well seen on cross-sectional abdominal imaging studies [1]. Various structures, including normal anatomic variants and extension of diseases from adjacent organs, can be detected within this space [1-3]. An awareness of the types of normal and abnormal structures can prevent misinterpretation and aid in evaluating the spread of malignant diseases. We describe the appearances of these entities within the portacaval space on several types of images.

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...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
