Imaging of Spinal Cord Tumors
Spinal cord tumors are rare but clinically significant, causing progressive neurological deficits. MRI is the modality of choice for diagnosis, localization, and surgical planning. 📍 Classification of Spinal Cord Tumors…
Postoperative Spine Imaging – A Radiology Guide
Spine surgery is increasingly common for degenerative disease, trauma, infection, and tumors. Imaging of the postoperative spine is often challenging but essential to distinguish expected changes from complications. 📍 Modalities…
MRI Myelography – Indications and Role
MRI Myelography is a non-invasive technique that uses heavily T2-weighted sequences to visualize the CSF spaces, spinal cord, and nerve roots without contrast injection. Unlike CT myelography, it avoids ionizing…
MRI in Degenerative Spine Disease
Degenerative spine disease is among the most common causes of back pain. MRI is the modality of choice, as it provides excellent soft tissue detail of discs, ligaments, marrow, and…
Spinal Tuberculosis (Pott’s Spine) – Imaging Features
Spinal tuberculosis is the most common skeletal manifestation of TB, usually involving the thoracic and lumbar spine. Early recognition on imaging is crucial to prevent deformity and neurological deficits. 📍…
MRI in Intracranial Neoplasms
🩺 Introduction Intracranial neoplasms range from benign extra-axial tumors (like meningiomas) to highly aggressive intra-axial gliomas. MRI is the gold standard for characterization, local staging, surgical planning, and treatment follow-up.…
Diffusion-Weighted MRI (DWI): Uses & Interpretation
🩺 Introduction Diffusion-weighted MRI (DWI) measures the random motion of water molecules (Brownian motion) within tissues. Pathological processes that alter tissue microstructure affect water diffusion, which is detected as signal…
Imaging of Soft Tissue Sarcomas
🩺 Introduction Soft tissue sarcomas (STS) are a heterogeneous group of malignant mesenchymal tumors. Imaging plays a crucial role in detection, characterization, local staging, biopsy planning, and treatment follow-up. 🖼️…
🚑 Imaging of Trauma: Acute ED CT Protocol
🩺 Introduction In acute trauma, time = life. CT has become the workhorse in emergency departments (ED) for rapid assessment of polytrauma patients. A standardized CT protocol ensures fast diagnosis…
