Core Concepts Of Cranial CT

This module introduces the essential principles of head CT imaging and explains how axial acquisition slice thickness and reconstruction algorithms influence visualization of brain structures. It describes how technologists evaluate gray white differentiation ventricular size sulcal patterns and bone detail. The content highlights the importance of selecting appropriate protocols for trauma stroke headache and postoperative evaluation. It also explains how patient motion can significantly degrade image quality and how immobilization and communication reduce this risk. The module emphasizes the importance of reviewing images for hemorrhage mass effect midline shift and sinus pathology. By understanding how head CT protocols are designed technologists can support rapid accurate diagnosis in urgent and routine settings.

Protocol Selection And Dose Considerations

This section explains how to tailor head CT protocols based on clinical indication. It describes how to adjust slice thickness kernel selection and exposure parameters to balance image quality and dose.

Patient Preparation And Workflow

This section focuses on preparing patients for head CT including communication strategies positioning techniques and safety considerations for contrast enhanced studies.
