Ventilation–perfusion (V/Q) lung scintigraphy performed with 99mTc-labeled agents for both phases requires careful control of the ventilation–to–perfusion count rate relationship. This is particularly ...

Mandibular condylar hyperplasia (CH) is a complex developmental deformity resulting in asymmetries of the hyperplastic condyle. Bone scan SPECT is a sensitive and accurate method of detecting the ...

Special collimators used in imaging systems play an important part in obtaining qualified images to improve diagnosis in medicine. Methods: The primary aim of this study was to compare resolution ...

Neurodegenerative disease profoundly affects structures and pathways responsible for memory, cognition, and higher-order processing. A foundational understanding of neuroanatomy and physiology is ...

Technegas is a carbon-based nanoparticle developed in Australia in 1984 and has been in widespread clinical use, including SPECT imaging, since 1986. Although 81m Kr offers the ideal ventilation ...

Ventilation and perfusion (V/Q) lung scintigraphy has been used in the assessment of patients with suspected pulmonary embolism for more than 50 y. Advances in imaging technology make SPECT and ...

Epilepsy is one of the most common yet diverse neurologic disorders, affecting almost 1%–2% of the population. Presently, radionuclide imaging such as PET and SPECT is not used in the primary ...

Obesity, with its alarming increase among adults and children, represents a significant health problem with serious medical, social, psychologic, and economic reverberations. The burden of this ...

With new radiopharmaceuticals constantly in development, the field of nuclear medicine is ever evolving. This continuing education article reviews some of the newer, less frequently used ...

Although prostate cancer has traditionally been regarded as a disease of older men, emerging evidence suggests a shift toward diagnosis at younger ages. Increased prostate-specific antigen screening ...

In 1966, Griffith et al. used “a standard breakfast of ordinary food” labeled with chromium-51 to report the first use of gastric emptying scintigraphy (GES). As the procedure was refined over the ...
