Cancer and active inflammation can cause increased use of oxygen and sugar. metabolic activity is the use of the oxygen and sugar. ... without a discrete dominant hypermetabolic lesion likely physiologic. ... what does is mean on pet scan there is opacity with weak activity could still be inflammatory in origin but neaplasms cannot not be ...


I also note that in the IMPRESSION section the only areas mentioned are the areas with hypermetabolic activity, not the areas with 'physiologic uptake'. I did see this when I first looked at the report but I assumed it was normal to have a physiologic uptake of glucose. Now I see it is not labled 'no abnormal uptake'.


The total uptake in the brain is approximately 6 % of the injected dose. Normal lymphatic tissue may display low to moderate FDG uptake in the head and neck region. This is seen in the lingual and palatine tonsils and at the base of the tongue because of physiologic activity associated with the lymphatic tissue in Waldeyer’s ring.


Research has repeatedly shown that exposure to regular, frequent bouts of physical activity stimulates physiological and metabolic changes that benefit health. It is helpful to classify these as either (a) chronic effects, that is, adaptations to training acquired over weeks or months, or (b) short-term, acute responses to each individual session of activity.


Esophageal adenocarcinoma in a 52-year-old man who was referred for presurgical evaluation. Axial PET scan (b) demonstrates an intense focus of metabolic activity (arrowhead) (cf ,,,, Fig 15). If no clinical information were available, it would be unclear whether this focus represented physiologic FDG uptake in the distal esophagus or a ...


In our study, increased muscle activity was frequently seen on 18 F-FDG PET scans (12.5%). We found common patterns of physiologic muscle uptake in 5 general anatomic regions. Most common areas of increased uptake were the head and neck, thorax, and upper extremities.


There are a number of lines of evidence linking glucocorticoids to both metabolic and psychiatric disorders. For one, glucocorticoid resistance—the inability to respond to the physiological concentrations of the hormones—has been found in more than 50 percent of mood disorder cases, which are known to be triggered by various types of stress.


I had Melanoma stage 3 in 2007 on right lower calf. Had large excision and SLNB. SLNB showed one node was positive. All Cat Scans and ultra sound have been good. I had a Pet Scan done this week. Findings: Head/face Focal ssymetric hypermetabolism is inseperable from the right parotid and inferior right auditory canal, suv 5.0. physiologic FDG uptake is seen in the visualized


Physiological activity refers to the normal function of an organism. It may refer to specific organs or the organism as a whole. The act of a human eating, sleeping or even thinking is considered a physiological activity.


metabolic activity of tissue. This primer is written primarily for practicing radiologists with only residency training in nuclear medicine and who are now interpreting PET/CT studies. It is intended as a succinct guide to practicing radiologists for interpretation of the images, as well as a
