Abstract:
A 67-year-old female presented with an acute compression fracture with an intravertebral vacuum cleft (IVC) sign of the T12 vertebra. Her bone scan demonstrated a cold defect of the fractured vertebra. Although the IVC sign is related to vertebral osteonecrosis, to the best of our knowledge, a cold defect on a bone scan has not been reported in an acute compression fracture with an IVC sign. In this case review, various imaging findings of osteonecrotic compression fractures are discussed along with a review of the current literature.

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...
