Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut It's a little-known fact that the discovery and (inadvertent) use of X-rays garnered the first ever Nobel Prize in Physics. The famous X-ray image of Dr. Röntgen's wife's hand from 1895 that sent shock waves through the scientific community looks like most modern day 2D medical X-ray images. Though it is not the newest technology, X-ray absorption...

Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana Here we will demonstrate the fundamentals of single-photon emission computed tomography/computed tomography (SPECT/CT) imaging using mice. The technique involves injecting a radionuclide into a mouse, imaging the animal after it is distributed throughout the body, and then reconstructing the produced images to create a volumetric dataset. This can...

This video demonstrates a technique for in vivo imaging of neuroinflammation in a mouse model of ischemic stroke using a TSPO-specific radiotracer. Following injection, the radiotracer binds to TSPO, a protein located on the outer mitochondrial membrane and overexpressed in activated immune cells. A PET/CT scanner detects the radiotracer's distribution and...

FAQs
During acquisition, the X-ray tube and detectors rotate around the head and record tissue-dependent attenuation from multiple angles. A computer processes these measurements and reconstructs them into detailed slices. This reconstruction converts raw transmission data into anatomical views that clinicians can examine for abnormalities involving the brain, skull, and surrounding tissues.
Different tissues attenuate X-rays to different degrees, creating measurable differences in the collected data. The computer uses those differences during reconstruction to represent anatomical structures within each slice. Because the resulting images include the brain, skull, and nearby tissues, attenuation patterns help show findings such as fractures, hemorrhage, or mass effect.
Contrast material can improve visualization of blood vessels or lesions that may be less conspicuous without enhancement. Its use adds information to the reconstructed images beyond the measurements obtained during the basic scan. Clinicians may therefore incorporate contrast when clearer assessment of vascular structures or suspected lesions is needed.
In trauma assessment, clinicians use Head CT to evaluate potential skull fractures, intracranial hemorrhage, and mass effect. These findings can indicate significant injury and help support urgent diagnostic and treatment decisions. The scan therefore contributes both structural information about the skull and information about complications affecting tissues within the head.
Head CT can assess stroke-related changes and identify intracranial hemorrhage, an important finding in acute neurological assessment. By providing detailed slices of the head, it gives clinicians imaging information that supports rapid evaluation and treatment decisions. Its role is especially relevant when neurological symptoms require prompt investigation.
Beyond trauma and stroke-related findings, clinicians can use Head CT to assess hydrocephalus and mass effect, along with abnormalities involving the skull and surrounding tissues. These applications extend the method across several urgent neurological presentations. The reconstructed slices help relate a suspected condition to the anatomy affected and guide clinical decision-making.
