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...

A method of functional imaging of mouse brown adipose tissue (BAT) is described in which cold-stimulated uptake of 18F-Fluorodeoxyglucose (FDG) in BAT is non-invasively assessed with a standardized micro-PET/CT protocol. This method is robust and sensitive to detect differences in BAT activities in mouse models.

FAQs
The reconstruction process translates detector measurements of X-ray attenuation into cross-sectional slices. Because the tube collects data as it rotates around the patient, the computer can represent differences in how tissues weaken the beam from multiple angles. Clinicians can review individual slices or combine them into three-dimensional views to examine anatomy, injury, or disease.
Iodinated contrast can improve the visibility of blood vessels and soft tissues during a scan. Its use helps clinicians distinguish structures that may be less apparent without contrast, supporting assessment of vascular disorders and other clinical findings. The contrast-enhanced images add information to the reconstructed views rather than replacing the underlying measurements collected by the scanner.
Radiation exposure is an important consideration because CT uses X-rays to generate its measurements. Clinical practice therefore requires appropriate justification before scanning, balancing the expected diagnostic value against exposure. This principle is especially relevant when clinicians choose CT for rapid assessment of suspected trauma, stroke, cancer, infection, or vascular disorders.
The scanner collects measurements while an X-ray tube rotates around the patient, and detectors record how the beam is attenuated from multiple angles. A computer then reconstructs those data into slices that can be examined separately or combined into three-dimensional views. This workflow gives clinicians several ways to assess the same region for anatomical or pathological findings.
Clinicians use CT scan imaging when rapid, detailed assessment is needed for conditions such as trauma, stroke, cancer, infection, and vascular disorders. The method can show anatomy and disease-related findings in cross-sectional views, helping support clinical evaluation. Its broad use reflects the ability to inspect both individual slices and combined three-dimensional representations.
Beyond diagnostic assessment, CT images can guide biopsies and support planning for surgery or radiation treatment. Cross-sectional slices help identify relevant anatomy, while three-dimensional combinations provide an additional view for organizing an intervention or treatment approach. In this way, the imaging output can contribute to both evaluation and decisions about subsequent clinical care.
