hoofdCT

HoofdCT, short for hoofd computed tomography, is a diagnostic imaging test that uses X-rays to create cross-sectional images of the head, including the brain, skull, and surrounding structures. Performed on a multidetector CT scanner, a non-contrast head CT is the most common initial study in acute settings. Contrast-enhanced studies, such as CT angiography or CT perfusion, may be added when vascular pathology or detailed brain tissue assessment is needed.

Indications include acute head trauma to detect fractures or bleeding; suspected intracranial hemorrhage; evaluation of suspected stroke to quickly distinguish hemorrhagic from non-hemorrhagic events; sudden severe headache suggestive of subarachnoid hemorrhage; altered consciousness; hydrocephalus or mass effect due to lesions.

Benefits include rapid acquisition, wide availability, and high sensitivity for acute bleeding. It is crucial for triage and guiding treatment decisions, such as surgery or thrombolysis planning.

Limitations include reduced sensitivity for very early ischemic changes, small bleeds, or certain posterior fossa abnormalities. It uses ionizing radiation, and contrast-enhanced studies carry risks of allergic reactions and kidney injury in susceptible patients.

Preparation is minimal: remove metal objects; inform staff about pregnancy, allergies, and kidney disease. After the exam, patients may resume normal activities unless contrast was used, in which case hydration is advised and monitoring for reactions is standard.

Results are reported as findings or absence of acute pathology, including hemorrhage, fracture, edema, mass effect, or midline shift, influencing urgent management.
