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...

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...

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
Different tissues attenuate, or weaken, X-rays by different amounts. The rotating source and detectors measure these differences from multiple directions, creating data that the computer can use to distinguish internal structures. In cancer research, this attenuation-based contrast helps reveal abnormalities and supports assessment of a tumor’s location, size, and relationship to nearby anatomy.
Computer reconstruction allows the collected measurements to be viewed in multiple planes and assembled into three-dimensional models. These views provide complementary perspectives on a lesion and surrounding structures rather than limiting interpretation to one image orientation. That flexibility supports more detailed anatomical assessment during tumor characterization and planning of biopsies or treatments.
Anatomic CT can show where a tumor is located, how large it is, and how it relates spatially to surrounding tissues. Examining these structural features helps researchers and clinical teams characterize abnormalities within their anatomical context. The resulting information can also establish a basis for comparing later scans and identifying changes over time.
The process begins with rotating X-ray measurements collected around the body region of interest. A computer then reconstructs those measurements into cross-sectional images, which can be reviewed in different planes or as three-dimensional models. Researchers use the resulting anatomical views to locate abnormalities, evaluate tumor structure, and support study-specific assessment of disease.
By showing a tumor’s position, dimensions, and relationship to nearby tissues, anatomic CT supplies anatomical information for planning an intervention. These images can help identify the abnormal region that requires attention and clarify its surrounding context. In cancer research, that information supports biopsy guidance and treatment planning without relying only on an isolated structural finding.
Anatomic CT can be used to monitor structural changes across time by comparing findings from different examinations. Changes in tumor size or other visible anatomical features may contribute to evaluating therapeutic response. This longitudinal role also supports disease characterization, because repeated imaging shows how the observed anatomy evolves during the research or treatment period.
