Machine learning (artificial intelligence) has the potential to vastly advance medical imaging, particularly computerized tomography (CT) scanning, by reducing radiation exposure and improving image quality. AI-based methods automatically segment organs or detect and characterize pathology and have been translated out of the research environment and into clinical practice to bring automation, increased sensitivity, and new…

Foot CT PET scan

Foot pain is a common problem in the daily routine of any orthopedic surgeon. It can be a clinical symptom of many different issues, from stress fractures to tumors. Multiple imaging modalities are available to help diagnose specific types of foot pain. A single scan could diagnose the cause of foot pain better and with…

Researchers at the University of Arizona have developed a rapid, simplified method for producing radio-labeling compounds used for positron emission tomography, also known as PET scans. University of Arizona alumnus Iman Daryaei, who led the research and development of the technology, co-invented the method during his doctoral studies in the Department of Chemistry and Biochemistry….

PET CT Cancer Detection

PET/CT is a form of hybrid imaging that combines computed tomography (CT), an anatomical imaging, with positron emission tomography (PET), a functional imaging. With the prevalence of personalized medicine, the information obtained by PET/CT and several other investigations would help the oncologist decide on the best treatment modality. When a metastasis is found and the…

PET vs CT scan

Positron emission tomography(PET)is a nuclear imaging technique that uses radioactive tracers that are ingested or injected and then absorbed by body tissue. A scan will show areas of greater absorption (where more chemical activity is occurring in the body), which may indicate disease. PET scans can provide details about how well blood or oxygen travels…

Covid Safety

Many men are sporting what is being called a “Covid Beard”.  This is basically men not shaving while they are at home and not at the office, growing that manly beard. But while it is a symbol of being quarantined or stuck at home, its actually a bad idea. That is because a beard significantly…

PET and PTSD

PET scan could identify people with PTSD who are at risk of suicide according to Yale University. Brain scans may be able to tell who is at risk of suicide by identifying high levels of a certain kind of cell associated with disordered thinking, a new study suggests. Researchers at Yale University may have found…

What is a PET scan?

What is a PET scan anyway? Well, its not for your beloved pet, the P-E-T in PET scan stands for Positron Emission Tomography. A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity….

Psychoradiology

PET Scans are increasingly being used to map, identify and help psychological issues. It a recent article published in Radiology Today Magazine, research is being made as researchers from several specialties, including neurology, neuroradiology, and the emerging field of psychoradiology, are looking at imaging to help spot depression in the brain and bring a more…

PET Scans and Alzheimers

In a recently published study, researchers announced that a type of PET scan can tell whether amyloid plaques are in the brain of a living person. The scan, they said, will allow doctors to change diagnoses or treatment plans for some people. The importance of the scan In amyloid PET imaging, “tracer molecules” stick to…
