CVJ stands for Craniovertebral Junction. On a CT scan, the CVJ refers to the anatomical region where the skull base meets the upper cervical spine, primarily the occiput, atlas (C1) and axis (C2). CVJ CT imaging assesses bony alignment, fractures, congenital anomalies, degenerative changes, and instability that can affect the brainstem, spinal cord, and vertebral arteries.

A cardiovascular (CV) CT scan is a non-invasive X‑ray test using computed tomography, often with intravenous contrast, to image the heart and blood vessels. It includes coronary CT angiography and calcium scoring to detect blockages, plaque, structural problems or aneurysms and to help plan treatment. The exam is quick and outpatient but involves ionizing radiation and potential contrast-related risks (allergic reaction, kidney effects).

A CV junction anomaly is a congenital or acquired abnormality of the craniovertebral junction — the connection between the skull base and the upper cervical spine (atlas and axis). These malformations (e.g., basilar invagination, atlanto‑axial instability, fusion) can compress the brainstem or spinal cord, causing neck pain, headaches, neurological deficits and balance problems. Diagnosis uses CT/MRI; treatment ranges from observation and braces to surgical decompression and fixation.

MRI of the CV junction is magnetic resonance imaging of the craniovertebral junction, including the occiput, atlas (C1), axis (C2), adjacent ligaments, brainstem and upper cervical spinal cord. It evaluates trauma, instability, congenital anomalies, infection, inflammation, tumors and degenerative disease, showing soft-tissue detail such as cord compression, edema, syrinx or ligamentous injury. Findings guide diagnosis, treatment decisions and surgical planning.

Treatment depends on cause and severity. Conservative care: analgesics, cervical immobilization (collar or halo), physiotherapy, and short-course steroids. Traction can reduce dislocation. Surgical options for instability or compression include posterior C1–C2 fusion or occipitocervical fusion, decompression (foramen magnum), and anterior odontoid resection via transoral or endoscopic endonasal approaches. Decisions are individualized, guided by imaging and neurologic status, with multidisciplinary care.
