Abstract:
Spinal arachnoid cysts (AC) are intraspinal extramedullary loculated cerebral spinal fluid collections. They are relatively uncommon lesions. Spinal AC often cause symptoms such as pain, weakness and radiculopathy. In this pictorial essay we demonstrate the main radiological features of spinal AC, as well as symptoms and complications associated with them. We also describe the main differential diagnoses.

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...
